Australian startup Cortical Labs is building computer chips that use biological neurons extracted from mice and humans, Fortune reports.

The goal is to dramatically lower the amount of power current artificial intelligence systems need to operate by mimicking the way the human brain.

According to Cortical Labs announcement, the company is planning to build technology that harnesses the power of synthetic biology and the full potential of the human brain in order to create a new class of AI that could solve societys greatest challenges.

The mouse neurons are extracted from embryos, according to Fortune, but the human ones are created by turning skin cells back into stem cells and then into neurons.

The idea of using biological neurons to power computers isnt new. Cortical Labs announcement comes one week after a group of European researchers managed to turn on a working neural network that allows biological and silicon-based brain cells to communicate with each other over the internet.

Researchers at MIT have also attempted to use bacteria, not neurons, to build a computing system in 2016.

As of right now, Corticals mini-brains have less processing power than a dragonfly brain. The company is looking to get its mouse-neuron-powered chips to be capable of playing a game of Pong, as CEO Hon Weng Chong told Fortune, following the footsteps of AI company DeepMind, which used the game to test the power of its AI algorithms back in 2013.

What we are trying to do is show we can shape the behavior of these neurons, Chong told Fortune.

This Startup's Computer Chips Are Powered by Human Neurons - Futurism

Skin Stem Cells Comments Off on This Startup’s Computer Chips Are Powered by Human Neurons – Futurism | April 2nd, 2020

Just before Christmastime, Howard Federoff got a tip from Washington: There was a new virus in China. And this one could be bad.

News report of the virus had not yet appeared. Federoff, a neuroscientist, was briefed because years before, he was vetted as part of a group he didnt give a name for the group to consult for the US government on emerging scientific issues. His day job, though, was CEO of Aspen Neurosciences, a Parkinsons cell therapy startup that days before had come out of stealth mode and gave word to investors they were hoping to raise $70 million. That, Federoff realized, would be difficult if a pandemic shut down the global economy.

I started thinking rather early onThere might be something on the horizon that we dont fully understand, Federoff told Endpoints News. We knew that if something did change, it could change rather quickly.

Operating with insight and knowledge other biotechs lacked access to, Federoff went into overdrive trying to close before Covid-19 hit the US, and he emerged today with $70 million in Series A funding led by OrbiMed. The other investors included Frazier Health Partners, Sam Altman and ARCH Venture Partners, the VC whose leader Robert Nelsen became one of the earliest and most prominent voices calling for change.

Weve had long conversations, Federoff said of him and Nelsen.

With the Series A, Federoff has convinced A-list investors to back one version of a long-sought solution to Parkinsons. Aspen will use stem cells grown from Parkinsons patients own skin tissue to grow dopamine neurons that can be implanted into the brain and hopefully replace the degenerating neurons. The idea has been around for decades, with the first transplant occurring in the 80s, but it was never scaleable. The technology to produce stem cells on demand didnt exist.

The company has a rival in BlueRock, which uses donor stem cells and which Bayer acquired in August at a valuation of $1 billion.

Over the winter, though, the investor hunt became less about pitching the science which Federoff says everyone agreed was promising than about beating the clock and investors rising worries about the economy. He prepared to work fast, turning an early meeting with Frazier at the JP Morgan Healthcare Conference into a pivotal one. As the months passed, he phoned investors multiple times a day to keep funding on track.

They were already in from the standpoint of the science, Federoff said. I could tell that there was a growing weariness about whether all that they had previously considered as part of their own respective portfolios outside of Aspen would all be possible.

The money he secured will help fund their Phase I trial on Parkinsons and a second program that uses a form of gene therapy to implant stem cells that have a genetic marker for Parkinsons edited out. The plan had been to start a trial in 2021, but Federoff knows there are no more guarantees.

At this time its not clear what Covid-19 will do to projections, he said.

'There was a growing weariness': Rushing against a pandemic clock, Aspen Neurosciences secures $70M Series A - Endpoints News

During the last 20 years, a large body of research has accumulated on the beneficial effects of infrared light in the range of 600 to 1000 nm. Infrared light can activate mitochondria, which in turn stimulate second messenger systems, DNA transcription, and growth factors.1,2 As a result, new synapses are formed, circuits regrow, and pluripotent stem cells differentiate into neurons.

Animal studies have shown that infrared photobiomodulation (PBM) may reduce the size and severity of brain injury and stroke, as well as diminish damage and physiological symptoms in depression, posttraumatic stress disorder (PTSD), Parkinson disease, and Alzheimer disease.1,3-6 Michael Hamblin, PhD, from the Wellman Center for Photomedicine at Massachusetts General Hospital in Boston, a leader in the field, describes PBM as the use of red or near-infrared light to stimulate, heal, regenerate, and protect tissue that has either been injured, is degenerating, or else is at risk of dying.1

Generally in medicine we shy away from the word heal when referring to the brain, and regenerate stirs vague recollections of Frankenstein. Nevertheless, early findings in mouse models of brain injury and disease have spawned a different sort of monster in the commercial world. The internet is now loaded with companies offering infrared LED helmets or pads for the treatment of traumatic brain injury (TBI) and other brain disorders, often based on exaggerated claims about healing the brain. Exorbitant prices in the thousands of dollars are charged for a device that can be made for less than $30. As a result, the public is misled and the potential scientific benefits of infrared light are sullied.

It is time to separate fact from fiction. Yes, infrared light can induce the cellular events described here, reduce the size of stroke injury or TBI in mouse models, and protect neurons from neurotoxins. But is treating a human with a 0.5-W LED the same as treating a mouse? Certainly not! When it comes to infrared light treatment, it is all a matter of getting there: the infrared light must be able to penetrate all the overlying tissue to reach the brain.

Can Infrared Light Reach the Brain?

Can 0.5-W LEDs penetrate human scalp and skull to reach the brain? The answer is No.2 My colleague, Larry Morries, DC, and I showed that these LEDs did not even penetrate 2 mm of human skin. In contrast, our laser device, which emits infrared light in the range of 10 to 15 W, was able to effectively penetrate human tissue. We found that 33% of our 10-W infrared laser energy penetrated 2 mm of human skin and delivered from 1.2% to 2.4% of the energy from our device 3 cm into the brain. These data were replicated in a study by Juanita Anders, PhD, and colleagues at the Uniformed Services University of Health Sciences.7

The human scalp and skull provide a significant barrier. Infrared light energy needs to be in the range of 0.9 to 15 J/cm2 at the target tissue to activate mitochondria and other cellular events.2-3,8-9 Even if a 0.5-W LED only had to penetrate the skull to reach the surface of the brain, it could only deliver 0.0064 J/cm2, or 1/140th of the minimum energy necessary to induce PBM.10 No energy would be expected to reach the depths of the brain needed to treat stroke, Parkinson disease, Alzheimer disease, or many brain injuries. Although more than 40% of the incident light from a light source may penetrate mouse skull, only 4.2% penetrates human skull.8,10

There is a hairier problem facing LED devices: human hair blocks infrared light. More than 98% of infrared light can be blocked by 2 mm of hair (ie, 9.764 W of a 10-W beam of 810 nm infrared light is absorbed by human hair).11 If 98% of the energy from a 0.5-W LED is absorbed by hair, 80% to 90% is absorbed by 2 mm of skin, and 96% of incident energy is attenuated by skull, then claims of neurophysiological benefits of LED-based devices become highly questionable.

Another misconception propagated by companies selling LED-based devices is that multiple LEDs somehow increase light penetration, even though each LED projects light on its own path. For example, 100 0.5-W LEDs do not generate 50 W on the brain, they generate 0.5 W on 100 spots.11 The argument that light scattering in the brain provides the cumulative value of multiple LEDs also falls apart if nothing can get through the overlying tissues.

Given that a small percentage (<1%) of incident infrared light gets through human scalp and skull, we must question the results of human trials of LEDs. Studies demonstrated small yet almost insignificant positive effects, and the benefits are generally transient.12 In contrast, our protocol yields persistent and robust clinical changes in patients with TBI, PTSD, and depression.

Treating TBI, PTSD, and Depression with Infrared Light

Our patented multi-Watt Neuro-Luminance approach involves transcranial infrared laser treatment (NILT), and in 2015 we published an initial open-label trial of 10 subjects with mild to moderate TBI.13 After a course of 10 NILT treatments (20 treatments in a subset of 4 patients), all patients experienced significant clinical improvement of symptoms, including headaches, cognitive problems, sleep disturbances, irritability, and depression. In telephone interviews every 6 months after treatment, patients report sustained improvements.12

An open-label clinical trial (n=39) of multi-Watt Neuro-Luminance demonstrated effectiveness for depression.4 Overall, 92% of patients responded and 82% remitted, which is notably better than the response rate for oral antidepressants. Patients saw benefits within 4 treatments, and some achieved resolution of depressive symptoms within 8 treatments. In follow-up telephone interviews, patients report sustained improvements. Similarly, in our unpublished data, using a protocol of 20 treatments, each lasting 24 minutes, over the course of 9 weeks, 20 patients with PTSD treated with multi-Watt NILT experienced reduced hyperarousal, anxiety, sleep disturbance, and nightmares.

LED Photobiomodulation in Comparison

Naeser and colleagues15 treated 2 patients with TBI daily for approximately 1 hour by applying 3 separate LED cluster heads (2 head; 1 foot). The first patient, who was 7 years post-TBI and had significant postconcussive symptoms, received weekly treatments over the course of 7 months and then daily treatments at home for more than 6 years. The patient experienced transient benefits, and if treatment was stopped, symptoms returned within 2 weeks.15 The second patient received daily treatments, and in 4 months, most symptoms improved, allowing her to return to work. This patient also noted that symptoms returned if treatments were stopped for more than 1 week.15

In an open-label study,16 11 patients with TBI and persistent cognitive dysfunction were treated for 18 sessions, each lasting 20 minutes, over the course of 6 weeks. At follow-up, there had been a significant effect on attention, inhibition, verbal learning and memory, and long-delay free recall.16 The LED treatment led to mild improvement in 3 of 5 cases of depression.

In 12 patients with TBI treated with 220 0.5-W LEDs for 18 sessions, each lasting 20 minutes, over the course of 6 weeks, there was significant improvement in psychological testing results (P =.45).17 However, the study did not correct for multiple comparisons, instead using parallel paired t-tests, which could exaggerate findings.18 PTSD has received considerably less attention.19,20

Cassano and colleagues21 described a 5-W laser treatment of 4 patients with depression. In a double-blind, sham-controlled extension of their initial findings, subjects in the treatment group received 16 treatments, each lasting 30 minutes, over the course of 8 weeks.22 In 13 completers, Hamilton-D-17 scores separated the treatment group from sham controls (mean score, 15.74.41 vs 6.17.86; P =.031). In contrast, in our open-label trial of a 13-W laser, the mean Hamilton-D-17 score decreased from baseline (mean score, 21.485.24 to 6.05.12; P =6.4510-13).23

Alternative Explanation for Clinical Response to LED Brain Treatments

Researchers, along with the human PBM field, need to reconsider the potential mechanisms underlying the meager improvements derived from LED-based devices. The light from LED devices may not penetrate beyond the skin, but could induce central nervous system benefits via a remote or systemic effect in irradiated skin, dubbed remote photobiomodulation.24

Infrared irradiation can have remote or indirect effects on tissue that has not been irradiated. For example, Braverman and colleagues25 demonstrated this indirect effect by creating matching skin lesions on the left and right dorsum of a rabbit, treating 1 side with infrared light. Both lesions showed accelerated healing relative to nonirradiated controls. Rochkind and colleagues26 demonstrated that remote PBM could occur in the peripheral nervous system and the central nervous system. After bilateral sciatic nerve crush, 1 side was irradiated with infrared light and the other side was not. Nerves on both sides showed enhanced recovery of function, and the number of anterior horn motor neurons was greater on both sides compared with nonirradiated controls.

Ganeshan and colleagues27 irradiated the dorsum and hind limbs of a rat with infrared light (670 nm) before injection of a neurotoxin (MPTP) and demonstrated reduced loss of dopaminergic neurons in rodents treated with indirect PBM to the skin compared with untreated controls. Given the overwhelming evidence that low-power LEDs do not penetrate the brain, it is more likely that the benefits of LED-based devices result from an effect mediated by the skin, where most, if not all, of the infrared energy is absorbed. In other words, LED-based devices may be working by remote PBM.

Conclusions

The excitement about the potential of infrared light therapy is not merely that it does not involve taking a pill. There is considerable enthusiasm about its potential to treat conditions such as TBI, dementia, and Parkinson disease. In our excitement, we must not overlook the unique physical limitations of light. Similarly, we must not imbue infrared light with magical powers. Infrared light can only work if it reaches target tissue.

Thus, a sharp divide can be drawn between LED-based treatment technologies, which offer minimal results and may not even reach the brain, and multi-Watt technologies that demonstrably reach the brain and offer lasting clinical benefit. Potentially, infrared light may prove to be effective for numerous neuropsychiatric conditions. However, for infrared light to work on the brain, it must be able to reach the brain.

BOTHELL, Wash.--(BUSINESS WIRE)-- Seattle Genetics, Inc.. (Nasdaq:SGEN) today provided an update on the phase 1b/2 multicohort EV-103 trial (also known as KEYNOTE-869) of PADCEVTM (enfortumab vedotin-ejfv) in combination with anti-PD-1 therapy pembrolizumab for the treatment of patients with unresectable locally advanced or metastatic urothelial cancer who are unable to receive cisplatin-based chemotherapy in the first-line setting. Based on recent discussions with the U.S. Food and Drug Administration (FDA), data from the randomized cohort K, along with other data from the EV-103 trial evaluating PADCEV combined with pembrolizumab as first-line therapy for cisplatin-ineligible patients, could potentially support registration under accelerated approval regulations in the United States. PADCEV is a first-in-class antibody-drug conjugate (ADC) that is directed against Nectin-4, a protein located on the surface of cells and highly expressed in bladder cancer.1

We are excited that EV-103 provides PADCEV with a potential pathway for U.S. accelerated approval in first-line metastatic urothelial cancer, said Roger Dansey, M.D., Chief Medical Officer at Seattle Genetics. Our initial data on the combination of PADCEV and pembrolizumab in previously untreated patients who could not receive cisplatin are encouraging.

EV-103 is a multi-cohort, open-label, multicenter phase 1b/2 trial of PADCEV alone or in combination, evaluating safety, tolerability and efficacy in muscle invasive urothelial cancer, and in locally advanced or metastatic urothelial cancer in first- or second-line settings. Cohort K from EV-103 is intended to enroll 150 patients randomized 1:1 to PADCEV monotherapy or PADCEV in combination with pembrolizumab in locally advanced or metastatic urothelial cancer patients who are ineligible for cisplatin-based chemotherapy. The primary outcome measure is objective response rate (ORR) per blinded independent central review (BICR) using RECIST 1.1 and duration of response (DoR).

In addition to EV-103, the recently initiated EV-302 phase 3 randomized clinical trial is intended to support global registrations and potentially serve as a confirmatory trial if accelerated approval is granted based on EV-103. The EV-302 trial is evaluating the combination of PADCEV and pembrolizumab with or without chemotherapy versus chemotherapy alone in patients with previously untreated locally advanced or metastatic urothelial cancer. Importantly, EV-302 includes metastatic urothelial cancer patients that are either eligible or ineligible for cisplatin-based chemotherapy. The trial is expected to enroll 1,095 patients and has dual primary endpoints of progression-free survival and overall survival. Both the EV-103 and EV-302 trials are being conducted in collaboration with Astellas and Merck.

FDA recently granted Breakthrough Therapy designation for PADCEV in combination with pembrolizumab for the treatment of patients with unresectable locally advanced or metastatic urothelial cancer who are unable to receive cisplatin-based chemotherapy in the first-line setting based on initial results from the EV-103 trial.

PADCEV (enfortumab vedotin-ejfv) was approved by the FDA in December 2019 and is indicated for the treatment of adult patients with locally advanced or metastatic urothelial cancer who have previously received a programmed death receptor-1 (PD-1) or programmed death-ligand 1 (PD-L1) inhibitor and a platinum-containing chemotherapy before (neoadjuvant) or after (adjuvant) surgery or in a locally advanced or metastatic setting. PADCEV was approved under the FDAs Accelerated Approval Program based on tumor response rate. Continued approval may be contingent upon verification and description of clinical benefit in confirmatory trials.2

About Bladder and Urothelial Cancer

It is estimated that approximately 81,000 people in the U.S. will be diagnosed with bladder cancer in 2020.3 Urothelial cancer accounts for 90 percent of all bladder cancers and can also be found in the renal pelvis, ureter and urethra.4 Globally, approximately 549,000 people were diagnosed with bladder cancer in 2018, and there were approximately 200,000 deaths worldwide.5

About PADCEV

PADCEV is a first-in-class antibody-drug conjugate (ADC) that is directed against Nectin-4, a protein located on the surface of cells and highly expressed in bladder cancer.6,7 Nonclinical data suggest the anticancer activity of PADCEV is due to its binding to Nectin-4 expressing cells followed by the internalization and release of the anti-tumor agent monomethyl auristatin E (MMAE) into the cell, which result in the cell not reproducing (cell cycle arrest) and in programmed cell death (apoptosis).8 PADCEV is co-developed by Astellas and Seattle Genetics.

- Novellus's patented mRNA-based cell-reprogramming technology creates unique mesenchymal stem cells (MSCs) with superior immunomodulatory properties and manufacturing advantages over primary adult donor-derived MSCs - much greater supply and faster scale-up

- MSCs prevent and suppress cytokine storm believed to be the cause of the severe inflammation of ARDS and now seen in COVID-19 patients

CRANFORD, N.J., April 1, 2020 /PRNewswire/ -- Citius Pharmaceuticals, Inc. ("Citius" or the "Company") (Nasdaq: CTXR), a specialty pharmaceutical company focused on developing and commercializing critical care drug products, today signed an exclusive six-month option agreement to in-license a stem-cell therapy for acute respiratory distress syndrome (ARDS) from a subsidiary of Novellus, Inc., a preclinical-stage biotechnology company based in Cambridge, MA.

Novellus's patented process uses its exclusive non-immunogenic synthetic messenger ribonucleic acid (mRNA) molecules to create induced pluripotent stem cells (iPSCs) that, in turn, generate mesenchymal stem cells (MSCs) with superior immunomodulatory properties. MSCs have been shown to be safe in over 900 clinical trials and to be safe and effective in treating a number of inflammatory diseases, including ARDS.

"ARDS is the most common cause of respiratory failure and mortality in COVID-19 patients. Currently, there is no proven treatment for ARDS. Literature supports the use of counter-inflammatory MSCs for ARDS, and papers published in China have shown that at least seven COVID-19 patients with ARDS responded to MSC therapy. Clearly this is an avenue that shows promise and should be pursued as a potential treatment for ARDS. We believe Novellus is at the forefront of creating allogeneic, iPSC-derived MSCs. These cells have the potential to overcome the limitations of MSCs derived from adult donors, which are telomere shortened and introduce variability into the manufacturing process," said Citius Chief Executive Officer Myron Holubiak.

Novellus Chief Science Officer Matt Angel, PhD, stated, "Using our mRNA-based cell-reprogramming technology, Novellus can provide a near-unlimited supply of MSCs for treating patients with ARDS, including those critically ill from COVID-19. These will be allogeneic ('off-the-shelf') cells that in vitro have demonstrated much greater expansion potential and much higher immunomodulatory protein expression than donor-derived MSCs. We are excited to employ our technology to such an urgent medical crisis and believe that our MSCs represent an ideal source of cells to be used in this extremely important development effort."

Holubiak added, "No effective pharmacotherapy for ARDS exists, and ARDS-related morbidity and mortality are high. MSCs have been studied in the treatment of lung injury, and we aim to build upon this work with Novellus's iPSC-derived MSCs to improve the immunomodulatory response in humans. We have assembled a team of experts who are dedicated to advancing this project to an Investigational New Drug (IND) application as quickly as possible."

About ARDSAcute respiratory distress syndrome (ARDS) is a type of respiratory failure characterized by rapid onset of widespread inflammation in the lungs. ARDS is a rapidly progressive disease that occurs in critically ill patients most notably now in those diagnosed with COVID-19. ARDS affects approximately 200,000 patients per year in the U.S., exclusive of the current COVID-19 pandemic, and has a 30% to 50% mortality rate. ARDS is sometimes initially diagnosed as pneumonia or pulmonary edema (fluid in the lungs from heart disease). Symptoms of ARDS include shortness of breath, rapid breathing and heart rate, chest pain, particularly while inhaling, and bluish skin coloration. Among those who survive ARDS, a decreased quality of life is relatively common.

Dublin, April 01, 2020 (GLOBE NEWSWIRE) -- The "Graft-Versus-Host Disease: Epidemiology Forecast in Asia-Pacific Markets to 2028" report has been added to ResearchAndMarkets.com's offering.

GvHD is a common complication of allogeneic HSCT that occurs when the donated (graft) cells are rejected and attack the host's cells as foreign. GvHD can progress from mild to severe forms as either aGvHD or cGvHD. Both aGvHD and cGvHD commonly affect organs such as the skin, gastrointestinal (GI) tract, liver, oral mucosa, and eyes. The global distribution of GvHD is directly dependent on transplantation-related factors, including the donor type, the age of the donor and the recipient, the sex parity between the recipient and the donor, the pre-transplantation conditioning regimen, and the use of GvHD prophylaxis pre- and/or post-transplantation.

The publisher epidemiologists utilized historical HSCT data available through country-wide registry reports in the 5GM to the best extent possible to arrive at a meaningful in-depth analysis and forecast for GvHD. In this analysis, The publisher epidemiologists provided detailed, clinically relevant segmentations for the diagnosed aGvHD and cGvHD incident cases. Further, The publisher epidemiologists used country-specific estimates using valid diagnostic criteria to present aGvHD and cGvHD prevalent, grades and mortality cases.

The following data describes epidemiology of GvHD cases. In 2018, the 5GM had 8,794 diagnosed incident cases of GvHD (aGvHD and cGvHD). This is expected to increase to 13,673 diagnosed incident cases by 2028, at an Annual Growth Rate (AGR) of 5.55%. This increase is partly attributed to the moderately rising trend in incidence in transplantation in the 5GM. In the 5GM, the diagnosed incident cases of aGvHD will increase from 4,650 cases in 2018 to 7,212 cases in 2028, at an Annual Growth Rate (AGR) of 5.51% per year, and the diagnosed incident cases of cGvHD will increase from 4,144 cases in 2018 to 6,461 cases in 2028, at an AGR of 5.59% per year.

TORONTO, March 31, 2020 /CNW/ - The Gairdner Foundation is pleased to announce the 2020 Canada Gairdner Award laureates, recognizing some of the world's most significant biomedical research and discoveries. During these challenging times, we believe it is important to celebrate scientists and innovators from around the world and commend them for their tireless efforts to conduct research that impacts human health.

2020 Canada Gairdner International AwardThe five 2020 Canada Gairdner International Award laureates are recognized for seminal discoveries or contributions to biomedical science:

Dr. Masatoshi TakeichiSenior Visiting Scientist, RIKEN Center for Biosystems Dynamics Research, Kobe, Japan; Professor Emeritus, Kyoto University, Kyoto, Japan

Dr. Rolf KemlerEmeritus Member and Director, Max Planck Institute of Immunobiology and Epigenetics, Freiburg, Germany

Awarded "For their discovery, characterization and biology of cadherins and associated proteins in animal cell adhesion and signalling."

Dr. Takeichi

The Work: The animal body is made up of numerous cells. Dr. Takeichi was investigatinghow animal cells stick together to form tissues and organs, and identified a key protein which he named 'cadherin'.Cadherin is present on the surface of a cell and binds to the same cadherin protein on the surface of another cell through like-like interaction, thereby binding the cells together. Without cadherin, cell to cell adhesion becomes weakened and leads to the disorganization of tissues. Dr. Takeichi found that there are multiple kinds of cadherin within the body, each of which are made by different cell types, such as epithelial and neuronal cells. Cells with the same cadherins tend to cluster together, explaining the mechanism of how different cells are sorted out and organized to form functional organs.

Further studies by Dr. Takeichi's group showed that cadherin function is supported by a number of cytoplasmic proteins, includingcatenins, and their cooperation is essential for shaping of tissues. His studies also revealed that the cadherin-dependent adhesion mechanism is involved in synaptic connections between neurons, which are important for brain wiring.

Dr. Kemler

The Work: Dr. Kemler, using an immunological approach, developed antibodies directed against surface antigens of early mouse embryos. These antibodies were shown to prevent compaction of the mouse embryo and interfered with subsequent development. Both Dr. Kemler and Dr. Takeichi went on to clone and sequence the gene encoding E-cadherin and demonstrate that it was governing homophilic cell adhesion.

Dr. Kemler also discovered the other proteins that interact with the cadherins, especially the catenins, to generate the machinery involved in animal cell-to-cell adhesion. This provided the first evidence of their importance in normal development and diseases such as cancer. It has been discovered that cadherins and catenins are correlated to the formation and growth of some cancers and how tumors continue to grow. Beta catenin is linked to cell adhesion through interaction with cadherins but is also a key component of the Wnt signalling pathway that is involved in normal development and cancer. There are approximately 100 types of cadherins, known as the cadherin superfamily.

Dr. Takeichi

The Impact: The discovery of cadherins, which are found in all multicellular animalspecies, has allowed us to interpret how multicellular systems are generated and regulated. Loss of cadherin function has been implicated as the cause of certain cancers, as well as in invasiveness of many cancers. Mutations in special types of cadherin result in neurological disorders, such as epilepsy and hearing loss. The knowledge of cadherin function is expected to contribute to the development of effective treatments against such diseases.

Dr. Kemler

The Impact: Human tumors are often of epithelial origin. Given the role of E-cadherin for the integrity of an epithelial cell layer, the protein can be considered as a suppressor of tumor growth. The research on the cadherin superfamily has had great impact on fields as diverse as developmental biology, cell biology, oncology, immunology and neuroscience. Mutations in cadherins/catenins are frequently found in tumors. Various screens are being used to identify small molecules that might restore cell adhesion as a potential cancer therapy.

Dr. Roel NusseProfessor & Chair, Department of Developmental Biology; Member, Institute for StemCell Biology andRegenerativeMedicine, Stanford University, School of Medicine.Virginia and Daniel K. Ludwig Professor of Cancer Research. Investigator, Howard Hughes Medical Institute

Awarded"For pioneering work on the Wnt signaling pathway and its importance in development, cancer and stem cells"

The Work: Dr. Nusse's research has elucidated the mechanism and role of Wnt signaling, one of the most important signaling systems in development. There is now abundant evidence that Wnt signaling is active in cancer and in control of proliferation versus differentiation of adult stem cells, making the Wnt pathway one of the paradigms for the fundamental connections between normal development and cancer.

Among Dr. Nusse's contributions is the original discovery of the first Wnt gene (together with Harold Varmus) as an oncogene in mouse breast cancer. Afterwards Dr. Nusse identified the Drosophila Wnt homolog as a key developmental gene, Wingless. This led to the general realization of the remarkable links between normal development and cancer, now one of the main themes in cancer research. Using Drosophila genetics, he established the function of beta-catenin as a mediator of Wnt signaling and the Frizzleds as Wnt receptors (with Jeremy Nathans), thereby establishing core elements of what is now called the Wnt pathway. A major later accomplishment of his group was the first successful purification of active Wnt proteins, showing that they are lipid-modified and act as stem cell growth factors.

The Impact: Wnt signaling is implicated in the growth of human embryos and the maintenance of tissues. Consequently, elucidating the Wnt pathway is leading to deeper insights into degenerative diseases and the development of new therapeutics. The widespread role of Wnt signaling in cancer is significant for the treatment of the disease as well. Isolating active Wnt proteins has led to the use of Wnts by researchers world-wide as stem cell growth factors and the expansion of stem cells into organ-like structures (organoids).

Dr. Mina J. Bissell Distinguished Senior Scientist, Biological Systems and Engineering Division, Lawrence Berkeley National Laboratory; Faculty; Graduate Groups in Comparative Biochemistry, Endocrinology, Molecular Toxicology and Bioengineering, University of California Berkeley, Berkeley, CA, USA

Awarded "For characterizing "Dynamic Reciprocity" and the significant role that extracellular matrix (ECM) signaling and microenvironment play in gene regulation in normal and malignant cells, revolutionizing the fields of oncology and tissue homeostasis."

The Work: Dr. Mina Bissell's career has been driven by challenging established paradigms in cellular and developmental biology. Through her research, Dr. Bissell showed that tissue architecture plays a dominant role in determining cell and tissue phenotype and proposed the model of 'dynamic reciprocity' (DR) between the extracellular matrix (ECM) and chromatin within the cell nucleus. Dynamic reciprocity refers to the ongoing, bidirectional interaction between cells and their microenvironment. She demonstrated that the ECM could regulate gene expression just as gene expression could regulate ECM, and that these two phenomena could occur concurrently in normal or diseased tissue.

She also developed 3D culture systems to study the interaction of the microenvironment and tissue organization and growth, using the mammary gland as a model.

The Impact:Dr. Bissell's model of dynamic reciprocity has been proven and thoroughly established since its proposal three decades ago and the implications have permeated every area of cell and cancer biology, with significant implications for current and future therapies. Dr. Bissell's work has generated a fundamental and translationally crucial paradigm shift in our understanding of both normal and malignant tissues.

Her findings have had profound implications for cancer therapy by demonstrating that tumor cells can be influenced by their environment and are not just the product of their genetic mutations. For example, cells from the mammary glands grown in two-dimensional tissue cultures rapidly lose their identity, but once placed in proper three-dimensional microenvironments, they regain mammary form and function. This work presages the current excitement about generation of 3D tissue organoids and demonstrates Dr. Bissell's creative and innovative approach to science.

Dr. Elaine FuchsHoward Hughes Medical Institute Investigator and Rebecca C. Lancefield Professor and Head of the Robin Chemers Neustein Laboratory of Mammalian Cell Biology and Cell Biology; The Rockefeller University, New York, NY, USA

Awarded"For her studies elucidating the role of tissue stem cells in homeostasis, wound repair, inflammation and cancer."

The Work: Dr. Fuchs has used skin to study how the tissues of our body are able to replace dying cells and repair wounds. The skin must replenish itself constantly to protect against dehydration and harmful microbes. In her research, Fuchs showed that this is accomplished by a resident population of adult stem cells that continually generates a shell of indestructible cells that cover our body surface.

In her early research, Fuchs identified the proteins---keratinsthat produce the iron framework of the skin's building blocks, and showed that mutations in keratins are responsible for a group of blistering diseases in humans. In her later work, Fuchs identified the signals that prompt skin stem cells to make tissue and when to stop. In studying these processes, Fuchs learned that cancers hijack the fundamental mechanisms that tissue stem cells use to repair wounds. Her team pursued this parallel and isolated and characterized the malignant stem cells that are responsible for propagating a type of cancer called "squamous cell carcinoma." In her most recent work, she showed that these cells can be resistant to chemotherapies and immunotherapies and lead to tumor relapse.

The Impact: All tissues of our body must be able to replace dying cells and repair local wounds. Skin is particularly adept at performing these tasks. The identification and characterization of the resident skin stem cells that make and replenish the epidermis, sweat glands and hair provide important insights into this fountain of youth process and hold promise for regenerative medicine and aging. In normal tissues, the self-renewing ability of stem cells to proliferate is held in check by local inhibitory signals coming from the stem cells' neighbours. In injury, stimulatory signals mobilize the stem cells to proliferate and repair the wound. In aging, these normal balancing cues are tipped in favour of quiescence. In inflammatory disorders, stem cells become hyperactivated. In cancers, the wound mechanisms to mobilize stem cells are hijacked, leading to uncontrolled tissue growth. Understanding the basic mechanisms controlling stem cells in their native tissue is providing new strategies for searching out refractory tumor cells in cancer and for restoring normalcy in inflammatory conditions.

2020 John Dirks Canada Gairdner Global Health AwardThe 2020 John Dirks Canada Gairdner Global Health Award laureate is recognized for outstanding achievements in global health research:

Professor Salim S. Abdool KarimDirector of CAPRISA (Centre for the AIDS Program of Research in South Africa), the CAPRISA Professor in Global Health at Columbia University, New York and Pro Vice-Chancellor (Research) at the University of KwaZulu-Natal, Durban, South Africa

Professor Quarraisha Abdool KarimAssociate Scientific Director of CAPRISA, Professor in Clinical Epidemiology, Columbia University, New York and Professor in Public Health at the Nelson Mandela Medical School and Pro Vice-Chancellor (African Health) at the University of KwaZulu-Natal, Durban, South Africa

Awarded"For their discovery that antiretrovirals prevent sexual transmission of HIV, which laid the foundations for pre-exposure prophylaxis (PrEP), the HIV prevention strategy that is contributing to the reduction of HIV infection in Africa and around the world."

The Work: UNAIDS estimates that 37 million people were living with HIV and 1.8 million people acquired HIV in 2017. In Africa, which has over two thirds of all people with HIV, adolescent girls and young women have the highest rates of new HIV infections. ABC (Abstinence, Be faithful, and use Condoms) prevention messages have had little impact - due to gender power imbalances, young women are often unable to successfully negotiate condom use, insist on mutual monogamy, or convince their male partners to have an HIV test.

In responding to this crisis, Salim and Quarraisha Abdool Karim started investigating new HIV prevention technologies for women about 30 years ago. After two unsuccessful decades, their perseverance paid off when they provided proof-of-concept that antiretrovirals prevent sexually acquired HIV infection in women. Their ground-breaking CAPRISA 004 trial showed that tenofovir gel prevents both HIV infection and genital herpes. The finding was ranked inthe "Top 10 Scientific Breakthroughs of 2010" by the journal, Science. The finding was heralded by UNAIDS and the World Health Organization (WHO) as one of the most significant scientific breakthroughs in AIDS and provided the first evidence for what is today known as HIV pre-exposure prophylaxis (PrEP).

The Abdool Karims have also elucidated the evolving nature of the HIV epidemic in Africa, characterising the key social, behavioural and biological risk factors responsible for the disproportionately high HIV burden in young women. Their identification of the "Cycle of HIV Transmission", where teenage girls acquire HIV from men about 10 years older on average, has shaped UNAIDS policies on HIV prevention in Africa.

The impact: CAPRISA 004 and several clinical trials of oral tenofovir led tothe WHO recommending a daily tenofovir-containing pill for PrEP as a standard HIV prevention tool for all those at high risk a few years later. Several African countries are among the 68 countries across all continents that are currently making PrEP available for HIV prevention. The research undertaken in Africa by this South African couple has played a key role in shaping the local and global response to the HIV epidemic.

2020 Canada Gairdner Wightman AwardThe 2020 Canada Gairdner Wightman Award laureate is a Canadian scientist recognized for outstanding leadership in medicine and medical science throughout their career:

Dr. Guy Rouleau Director of the Montreal Neurological Institute-Hospital (The Neuro); Professor & Chair of the Department of Neurology and Neurosurgery, McGill University; Director of the Department of Neuroscience, McGill University Health Center

Awarded "For identifying and elucidating the genetic architecture of neurological and psychiatric diseases, including ALS, autism and schizophrenia, and his leadership in the field of Open Science."

The Work: Dr. Rouleau has identified over 20 genetic risk factors predisposing to a range of brain disorders, both neurological and psychiatric, involving either neurodevelopmental processes or degenerative events. He has defined a novel disease mechanism for diseases related to repeat expansions that are at play in some of the most severe neurodegenerative conditions. He has significantly contributed to the understanding of the role of de novo variants in autism and schizophrenia. In addition, he has made important advances for various neuropathies, in particular for amyotrophic lateral sclerosis (ALS) where he was involved in the identification of the most prevalent genetic risk factors -which in turn are now the core of innumerable ALS studies worldwide.

Dr. Rouleau has also played a pioneering role in the practice of Open Science (OS), transforming the Montreal Neurological Institute-Hospital (The Neuro) into the first OS institution in the world. The Neuro now uses OS principles to transform research and careand accelerate the development of new treatments for patients through Open Access, Open Data, Open Biobanking, Open Early Drug Discovery and non-restrictive intellectual property.

The Impact: The identification of genetic risk factors has a number of significant consequences. First, allowing for more accurate genetic counselling, which reduces the burden of disease to affected individuals, parents and society. A revealing case is Andermann syndrome, a severe neurodevelopmental and neurodegenerative condition that was once relatively common in the Saguenay-Lac-St-Jean region of Quebec. Now this disease has almost disappeared from that population. Second, identifying the causative gene allows the development of treatments. For instance, his earlier work on a form of ALS linked to the superoxide dismutase-1 gene (SOD1) opened up studies which are now the focal point of phase 2 clinical studies showing great promise.

2020 Canada Gairdner Awards Recognize World-renowned Scientists for Transformative Contributions to Research That Impact Human Health - Benzinga

Skin Stem Cells Comments Off on 2020 Canada Gairdner Awards Recognize World-renowned Scientists for Transformative Contributions to Research That Impact Human Health – Benzinga | April 1st, 2020

Researchers at Stanford University report that they can rejuvenate human cells by reprogramming them back to a youthful state. They hope that the technique will help in the treatment of diseases, such as osteoarthritis and muscle wasting, that are caused by the aging of tissue cells.

A major cause of aging is thought to be the errors that accumulate in the epigenome, the system of proteins that packages the DNA and controls access to its genes. The Stanford team, led by Tapash Jay Sarkar, Dr. Thomas A. Rando and Vittorio Sebastiano, say their method, designed to reverse these errors and walk back the cells to their youthful state, does indeed restore the cells vigor and eliminate signs of aging.

In their report, published on Tuesday in Nature Communications, they described their technique as a significant step toward the goal of reversing cellular aging and could produce therapies for aging and aging-related diseases.

Leonard P. Guarente, an expert on aging at M.I.T., said the method was one of the most promising areas of aging research but that it would take a long time to develop drugs based on RNA, the required chemical.

The Stanford approach utilizes powerful agents known as Yamanaka factors, which reprogram a cells epigenome to its time zero, or embryonic state.

Embryonic cells, derived from the fertilized egg, can develop into any of the specialized cell types of the body. Their fate, whether to become a skin or eye or liver cell, is determined by chemical groups, or marks, that are tagged on to their epigenome.

In each type of cell, these marks make accessible only the genes that the cell type needs, while locking down all other genes in the DNAs. The pattern of marks thus establishes each cells identity.

As the cell ages, it accumulates errors in the marking system, which degrade the cells efficiency at switching on and off the genes needed for its operations.

In 2006 Dr. Shinya Yamanaka, a stem-cell researcher at Kyoto University, amazed biologists by showing that a cells fate could be reversed with a set of four transcription factors agents that activate genes that he had identified. A cell dosed with the Yamanaka factors erases the marks on the epigenome, so the cell loses its identity and reverts to the embryonic state. Erroneous marks gathered during aging are also lost in the process, restoring the cell to its state of youth. Dr. Yamanaka shared the 2012 Nobel Prize in medicine for the work.

But the Yamanaka factors are no simple panacea. Applied to whole mice, the factors made cells lose their functions and primed them for rapid growth, usually cancerous; the mice all died.

In 2016, Juan Carlos Izpisua Belmonte, of the Salk Institute for Biological Studies in San Diego, found that the two effects of the Yamanaka factors erasing cell identity and reversing aging could be separated, with a lower dose securing just age reversal. But he achieved this by genetically engineering mice, a technique not usable in people.

In their paper on Tuesday, the Stanford team described a feasible way to deliver Yamanaka factors to cells taken from patients, by dosing cells kept in cultures with small amounts of the factors.

If dosed for a short enough time, the team reported, the cells retained their identity but returned to a youthful state, as judged by several measures of cell vigor.

Dr. Sebastiano said the Yamanaka factors appeared to operate in two stages, as if they were raising the epigenomes energy to one level, at which the marks of aging were lost, and then to a higher level at which cell identity was erased.

The Stanford team extracted aged cartilage cells from patients with osteoarthritis and found that after a low dosage of Yamanaka factors the cells no longer secreted the inflammatory factors that provoke the disease. The team also found that human muscle stem cells, which are impaired in a muscle-wasting disease, could be restored to youth. Members of the Stanford team have formed a company, Turn Biotechnologies, to develop therapies for osteoarthritis and other diseases.

The study is definitively a step forward in the goal of reversing cellular aging, Dr. Izpisua Belmonte said.

A diverse group of eight scientists whose work has offered insight into how cells interact with each other and their environment, the genetic underpinnings of neurological disease and the transmission of the virus that causes AIDS, have been named this years winners of the Gairdner Awards the countrys most prestigious biomedical research prizes.

Coming in the midst of the COVID-19 pandemic, this years set of awards highlights the importance of basic science to understanding the fundamental processes of life and how those processes relate to human health around the world.

When you build up a scientific environment and a scientific community, you have people who are prepared to do whatever it takes [to address a global health crisis], said Janet Rossant, president and scientific director of the Toronto-based Gairdner Foundation, which announced the award winners on Tuesday. You never know whats going to give you insight into disease, Dr. Rossant said.

Among the winners is Guy Rouleau, director of the Montreal Neurological Institute and Hospital, who is this years recipient of the Gairdner Wightman Award, which recognizes scientific leadership in Canada.

In addition to his work linking various rare genes that occur in the French Canadian population to disorders such as ALS (Amyotrophic Lateral Sclerosis), Dr. Rouleau is known for his efforts to make scientific research more accessible.

Starting in 2016, he placed his institute at the forefront of the open science movement by allowing the free flow of data, tools and research results without restrictions related to who will profit from the knowledge.

Reached at his home in Montreal, Dr. Rouleau said the initiative was spurred by a lack of new development in neurological disease, where few treatment options are available for those dealing with brain disorders including Alzheimers disease. We thought that by sharing openly and by breaking down barriers, this would accelerate things, Dr. Rouleau said.

The husband and wife team of Quarraisha and Salim Abdool Karim at the Centre for the AIDS Programme of Research in South Africa were named the joint winners of the John Dirks Gairdner Globe Health award for their work tackling HIV in Africa.

In 1990, the pair described the transmission of the virus that causes AIDS through the African population, which frequently involves the infection of teenage girls by older men. Their work laid the foundations for successful HIV prevention programs focused on women and womens health.

Previous winners of the global health award include Anthony Fauci of the National Institutes of Health in Bethesda, Md., who has lately become a prominent figure for helping to steer the U.S. response to COVID-19 and for repeatedly clarifying or correcting misleading statements by U.S. President Donald Trump.

The five researchers named as recipients of this years Canada Gairdner International Award a prize that often portends a future Nobel win have all done groundbreaking work related to some aspect of the field known as cell signalling.

They include:

In previous years, Gairdner award winners have travelled across Canada giving lectures and meeting with students ahead of a fall symposium and award ceremony in Toronto.

Dr. Rossant said the Foundation is still assessing how this years activities will proceed in light of COVID-19.

They say its the little things that matter, and when it comes to skincare, we have to agree. Few things feel better than the sensation of a freshly scrubbed face. Trouble is, few of us know how to actually get that feeling consistently. Sure, you may know that the key to a clear, healthy complexion is exfoliation (i.e., shedding the uppermost layer of dead skin cells). But what you use to exfoliate makes a big difference in whether you come away with a radiant glow or a mask of raw, irritated epidermis.

There are a few types of products that will do the job, but exfoliating face scrubs are often the most preferred. Known as physical exfoliants (as opposed to chemical exfoliants), these facial scrubs use tiny abrasive grains that act like sandpaper on your face, using friction to buff dead skin cells away. Physical exfoliants can be made from natural ingredients like apricot kernels, sugar, even coffee, or they can be synthetic beads that dissolve as you use them. Some guys love this type of exfoliant because you can really feel it working. However, it can be pretty harsh on some sensitive skin, leaving your face red and irritated, which leads to dry skin, increased oil production, or even scarring (and not in a sexy Jason Momoa kind of way).

That doesnt mean you shouldnt use an exfoliating scrub. It just means you have to do your homework or, if youd rather, have us do it for you. Weve put together a list of our favorite exfoliating face scrubs that contain quality ingredients for buffing away dead skin, and soothing the new skin underneath so that it stays happy, hydrated, and balanced. Gently (and we mean gently) massage these facial exfoliator scrubs into your forehead, chin, and cheeks, splash with cold water, pat dry, and finish with a kiss of moisturizer, and youll feel your face glowing all day long.

Finely ground apricot seed sloughs away yesterdays skin, with a little extra help from papaya extract enzymes, while chamomile, aloe, and sea kelp nourish and hydrate whats underneath.

For nights when youre ready to do some deep cleaning, pick this ultra-pure exfoliating mask. Activated charcoal and bentonite clay absorb impurities from your skin while the mask remains on your face. Scrubbing it off leaves your face not only clear, but also unbelievably soft, thanks to the addition of willow bark, rosemary extract, and sulfur mud.

Ground walnut shells and bamboo stem polish your skin, while jojoba esters and tropical fruit extracts break down pore-clogging oils, and special hydrating sugar technology blend rebuilds your skins moisture barrier before you rinse clean.

This super-concentrated, double-action exfoliating face scrub doesnt play around. Tiny jojoba beads offer a physical exfoliation that is boosted with the chemical exfoliating power of glycolic and salicylic acid. Five minutes with this scrub, and youll look and feel like a new man.

Sometimes, the simplest solutions are the best. This easy-to-find face scrub boasts natural ingredients such as aloe, hemp, and other nutrient-rich botanicals that ensure your newly scrubbed skin doesnt get dry or irritated.

Give Your Face a Spring Refresh With These Exfoliating Face Scrubs - The Manual

Skin Stem Cells Comments Off on Give Your Face a Spring Refresh With These Exfoliating Face Scrubs – The Manual | March 31st, 2020

A team of University of California, Irvine researchers have published the first comprehensive overview of the major changes that occur in mammalian skin cells as they prepare to heal wounds. Results from the study provide a blueprint for future investigation into pathological conditions associated with poor wound healing, such as in diabetic patients.

"This study is the first comprehensive dissection of the major changes in cellular heterogeneity from a normal state to wound healing in skin," said Xing Dai, PhD, a professor of biological chemistry and dermatology in the UCI School of Medicine, and senior author. "This work also showcases the collaborative efforts between biologists, mathematician and physicists at UCI, with support from the National Institute of Arthritis & Musculoskeletal & Skin Diseases-funded UCI Skin Biology Resource-based Center and the NSF-Simons Center for Multiscale Cell Fate Research.

The study, titled, "Defining epidermal basal cell states during skin homeostasis and wound healing using single-cell transcriptomics," was published this week inCell Reports.

"Our research uncovered at least four distinct transcriptional states in the epidermal basal layer as part of a 'hierarchical-lineage' model of the epidermal homeostasis, or stable state of the skin, clarifying a long-term debate in the skin stem cell field," said Dai.

Using single-cell RNA sequencing coupled with RNAScope and fluorescence lifetime imaging, the team identified three non-proliferative and one proliferative basal cell state in homeostatic skin that differ in metabolic preference and become spatially partitioned during wound re-epithelialization, which is the process by which the skin and mucous membranes replace superficial epithelial cells damaged or lost in a wound.

Epithelial tissue maintenance is driven by resident stem cells, the proliferation and differentiation dynamics of which need to be tailored to the tissue's homeostatic and regenerative needs. However, our understanding of tissue-specific cellular dynamics in vivo at single-cell and tissue scales is often very limited.

"Our study lays a foundation for future investigation into the adult epidermis, specifically how the skin is maintained and how it can robustly regenerate itself upon injury," said Dai.

Study reveals how skin cells prepare to heal wounds - Jill Lopez

Skin Stem Cells Comments Off on Study reveals how skin cells prepare to heal wounds – Jill Lopez | March 30th, 2020

It is a universally acknowledged fact that the majority of women refuse to age, the moment they reach the age of 40. The desire to turn back the clock is something that gets automatically etched on their minds, after hitting middle age. Making a wise choice from the wide range of anti-ageing solutions available for women can be a highly baffling affair, but understanding the skins needs is equally crucial.

So what exactly is ageing, that every person, especially women dread? It can be regarded as a complex process resulting in accrual changes in a persons body over. a period of time. Ageing occurs in fractions, because the stem cells which have the ability to renew themselves grow old as DNA gets damaged and changes occur in the overall physiology. As time passes by and people age, the majority of the cells present in their bodies get replaced and the ability of the body to produce more new cells gradually declines, Thus, anti-ageing retards the degeneration process of the body.

Post an anti-ageing fat stem cell treatment the skin shows prominent signs of turning softer while the body notices a remarkable surge of energy, resulting in improved sleeping and breathing patterns, controlled sugar levels, rebalanced hormones, increased metabolism, average weight loss and fading age spots. This all seems possible owing to the insertion of 30-50 million supercharged active stem cells.

Ageing is indeed complex, as its causes have not yet been completely understood. A big part of ageing occurs when the body is being attacked by inflammation and oxidative stress. Even though it is said that ageing is a natural process which is unavoidable, there is still scope to maintain health and stay young for both preventing age-related diseases and to enjoy the benefits of youth.

The desire to be younger is not exactly a new idea. The concept of anti-ageing has kept humankind occupied since ages, with the idea about staying healthy and fit with age and improving the quality of life. So with the rising evidence about the association of ageing diseases with adult stem cell exhaustion, it will not be surprising to witness an elevation of interest towards restoring the adult stem cell function to improve these conditions and to turn back the clock!

Reversing The Ageing Process With Stem Cell Therapy - Version Weekly

Skin Stem Cells Comments Off on Reversing The Ageing Process With Stem Cell Therapy – Version Weekly | March 30th, 2020

Gerlinde R. Van de Walle, DVM, Ph.D., co-lead for the study.

DURHAM, N.C. (PRWEB) March 26, 2020

Researchers have potentially made a breakthrough in the war on antibiotic-resistant superbugs including MRSA, which kills an estimated 20,000 people in the United States alone each year with a new discovery whose details are published today in STEM CELLS Translational Medicine. The study, by researchers at The Baker Institute for Animal Health, at Cornells College of Veterinary Medicine, demonstrates for the first time that mesenchymal stromal cells (MSCs) are an effective weapon against bacteria in biofilm.

Biofilms are thin, slimy films made up of bacteria that can attach to skin wounds, teeth and other surfaces, creating the opportunity for infections to flourish. These highly structured cellular communities offer bacteria shelter from harmful factors, helping them resist antibiotics, mutate rapidly and evade the immune system.

MSCs help kill the bacteria through the secretion of enzymes, called proteases, that break the peptide bonds of proteins and cause biofilm to destabilize. This in turn increases the effectiveness of antibiotics that previously werent working, as the bacteria are no longer being protected by the biofilm, explained Gerlinde R. Van de Walle, DVM, Ph.D., who led the study along with Charlotte Marx, DVM, Ph.D.

Other recent studies, including one by the Cornell team, have shown that MSCs can inhibit the growth of bacteria associated with chronic infections by secreting antimicrobial peptides. But these studies were conducted primarily on planktonic bacteria, which are individually floating bacteria cells. Thus, information on the effects on biofilms was largely lacking, Dr. Marx said.

The current study explores how MSC secretome, delivered as conditioned medium, performs against various wound-related bacterial pathogens. It also looks at the mechanisms that affect bacterial biofilms. The experiments were performed in vitro, using equine MSC. We use equine MSC in our work since the horse represents a physiologically relevant model for human wound healing and offers a readily translatable model for MSC therapies in humans, Dr. Van de Walle explained.

The researchers began by showing that equine MSC secretome inhibits the growth of four types of planktonic bacteria that commonly colonize skin wounds. Encouraged by the results, they next sought to determine the effect of the MSC secretome on these same bacterial strains in biofilms, which is the predominant way bacteria invade wounds. They looked at how the MSCs affected biofilm formation, then repeated the experiments on biofilms that were already established. Finally, they turned their attention to the bacteria strain responsible for MRSA.

Dr. Marx reported the results. Our salient findings, she said, were that factors secreted by equine MSC impaired both planktonic and biofilms including MRSA as well as disrupted mature biofilms generated by these bacteria. Importantly, we found that these effects resulted from a protease-dependent mechanism.

Dr. Van de Walle added, We also found that MSC-secreted factors allowed previously ineffective antibiotic treatments to become more effective at reducing bacterial survival. In light of the rise of antibiotic-resistant bacterial strains as an increasing global health threat, our findings provide the rationale for using the MSC secretome as a complementary treatment for bacterial infections.

Outcomes from this study highlight for the first time that the secretome from mesenchymal stem cells significantly reduces the formation of bacterial infections, including the antibiotic resistant MRSA, said Anthony Atala, M.D., Editor-in-Chief of STEM CELLS Translational Medicine and director of the Wake Forest Institute for Regenerative Medicine. Antibiotic resistance has long been a concern and this research highlights some promising new tactics.

Skin Stem Cells Comments Off on Study offers potential breakthrough in the war on antibiotic-resistant superbugs – PR Web | March 30th, 2020

The electronic newsletter I Love My Freedom on a regular basis blasts out e-mails hawking ostentatious rip-offs as well as serpent oil, such as a dementia-reversing miracle therapy, a diabetes destroyer material as well as a life-saving cancer cells treatment that a Nazi drug store allegedly established at Hitlers command. Peppered in between these messages funded by third-party hucksters are main advertisements from Donald Trumps governmental reelection campaign.

For months, participants of the head of states internal circle consisting of Donald Trump Jr., Senate Majority Leader Mitch McConnell (R-Ky), previous House Speaker Newt Gingrich as well as also Trump himself have actually been releasing require contributions with the newsletter, which usually heads out 5 or even more times each day. Many receivers were most likely unintentionally subscribed; I Love My Freedom, the team that runs the eponymous newsletter, has actually obtained an expanding checklist of Americans call info with a concealed e-mail collecting system including an internet of pro-Trump Facebook web pages.

Right- wing political leaders, companies as well as media electrical outlets have a background of dealing with unethical entities behind the scenes to earn money as well as press their programs. The Trump campaigns service with I Love My Freedom is no exemption.

I Love My Freedom (e-mail information multiplied by HuffPost).

By layout, its e-mails seem theyre sent out straight from Trump as well as his allies, though theyre in fact dispersed by means of [emailprotected] At all-time low, they birth please notes noting they were spent for by either the National Republican Senatorial Committee, its House equivalent, the McConnell Senate Committee, or the Trump Make America Great Again Committee (which is collectively run by the Republican National Committee as well as Trumps reelection campaign).

Renting out accessibility to collected e-mail listings is a typical as well as very profitable method worked out by traditional as well as liberal teams alike, commonly for political fundraising objectives. But points obtain morally dirty when e-mail representatives do not veterinarian their enrollers which can lead to e-mail receivers being flooded with ripoffs as well as scams, like the counterfeit cancer cells treatment. In this instance, nonetheless, the genuine inquiry is whether Trumps group troubled to veterinarian I Love My Freedom.

The campaign did not react to HuffPosts ask for remark.

I Love My Freedom, which makes up the newsletter as well as a conservative blog site called Trending Politics, belongs to Making Web LLC, a rare advertising company thats signed up in Minnesota to a 51- year-old male called Allan G. Ferretti.

Through the newsletter alone, I Love My Freedom has actually enhanced a list of aggressive rip-offs consisting of some that misleadingly link Trump, in spite of its negotiations with his campaign. Hours prior to dispersing a fundraising e-mail from the McConnell Senate Committee this month, I Love My Freedom discharged off a funded message advertising a breakthrough stem cell therapy which it baselessly suggested Trump is getting.

This has got Liberals jumping out of their seats, the e-mail checks out. President Trump is in perfect health how is it that hes so seemingly immune to old age? Well in recent years, billionaires like President Trump have increasingly turned to the power of Stem Cells.

Titled Trump Health Bombshell, the e-mail web links to a rambling item pitch that promotes $67 containers of stem cell tablets as the Holy Grail of aging backwards. These tablets make cells inside your body become physically younger, it asserts, without supplying a shred of clinical proof. I Love My Freedom has likewise spammed its customers with enrollers get-rich-quick plans consisting of a secret IRS loophole, as well as has actually routed them to video clips recommending elders ought to exchange their recommended medicines for tricksters supplements also advising that they can pass away if they do not.

Recent newsletter versions have actually circulated actual phony information, as well, installing advertisements camouflaged as write-ups that connect to internet sites stealthily copying genuine media electrical outlets.

I Love My Freedom e-newsletters have actually included misleading advertisements resulting in phony information websites copying genuine electrical outlets..

One such advertisement includes the message Royal Family Mourns As Tragedy Is Confirmed, along with a picture of Meghan Markle, the Duchess ofSussex Clicking on it causes a web site imitating U.S.A. Today that goes crazy regarding a skin care line, which it incorrectly asserts Markle released. Another, birthing the heading [BREAKING NEWS] Prayers Go Out to Oprah Winfrey, web links to a fraudulent information website marketing a Brain Booster supplement, which it brazenly states is in charge of Winfreys occupation success.

In enhancement to Trump, his oldest kid, McConnell as well as Gingrich, I Love My Freedom has actually likewise sent fundraising e-mails in behalf of previous White House press assistant Sarah Huckabee Sanders, House Minority Leader Kevin McCarthy (R-Calif), House Republican Whip Steve Scalise (R-La), previous United Nations Ambassador Nikki Haley,Rep Elise Stefanik (R-N.Y.),Rep David Joyce (R-Ohio), previous White House Deputy Chief of Staff Karl Rove as well as National Republican Congressional Committee Chairman TomEmmer

All were spent for by the NRCC, NRSC, McConnell Senate Committee or the Trump Make America Great AgainCommittee Only the NRCC reacted to an ask for remark.

We rented this list to prospect new donors. We do our best to vet each vendor, but similar to renting a car, it is impossible to know or control what every other renter does with a list they too are renting, spokesperson Chris Pack informed HuffPost.

We will not be using this vendor going forward.

I Love My Freedom constructed its cash-cow e-mail realm by spending virtually $2 million right into Facebook advertisements, which attract individuals in with clickbait surveys or pledges of free MAGA equipment, as well as result in web pages advising them to send their e-mail addresses. This immediately indications them as much as obtain the newsletter, in addition to its numerous funded messages.

The team likewise earns money by marketing Trump- themed product such as Make Liberals Cry Again hats, as well as organizing third-party advertisements on Trending Politics which was seen a million times last month alone, according to electronic analytics device ComparableWeb

I Love My Freedom did not accept HuffPosts ask for a meeting.

I Love My Freedom makes use of clickbait Facebook advertisements to gather individualss e-mails, after that subscribes them to its newsletter.

Ferretti released ilovemyfreedom.org in addition to the Facebook web page Trump for President Fan Club (currently President Donald Trump Fan Club, which has 1.6 million fans) in the summertime of 2015, as reporter April Glaser reported last loss in a write-up regarding I Love My Freedoms viral development on Facebook.

Its among greater than a lots preferred web pages the team runs to run its countless Facebook advertisements, consisting of Donald Trump Is My President, Donald Trump 2020 Voters, President Trump Has My Vote, Donald Trumps Americans, Team Trump Fan Club, The President Trump Fan Club, We Need Trump 2020 as well as President Trumps Patriot Army.

These web pages create a stream of hyper-partisan memes as well as Trending Politics post to their target market of millions. Boosted by Facebooks formula, the advertisements which largely target elders are in some cases seen thousands of countless times each.

This looks like an operation thats got a very highly engaged audience that would be a prime target for a lot of conservative politicians to try to raise grassroots money from, stated Michael Beckel, research study supervisor at the political reform team Issue One.

When you run a pro-Trump Facebook team with greater than a million participants, that can make your [email] checklist an appealing possession.

Trumps campaign has actually currently gathered a citizen e-mail checklist thats so big it leases it out to outdoors celebrations. So why would certainly his group wish to fundraise with I Love My Freedoms checklist particularly provided the teams historical connections to grifters as well as scam artist?

Its type of striking that the Trump campaign is making a financial investment in [I Love My Freedoms] checklist, kept in mindBeckel But a t completion of the day, he stated, much more e-mails still means more potential voters or donors for them.

Donald Trump Is Using An Insanely Sketchy Newsletter To Find Campaign Donors - The Union Journal

Skin Stem Cells Comments Off on Donald Trump Is Using An Insanely Sketchy Newsletter To Find Campaign Donors – The Union Journal | March 28th, 2020

The development of bone marrow transplantation procedures is widely considered one of the greatest victories in the war against cancer. The vast majority of bone marrow transplant recipients are patients with various forms of blood cancers, such as leukaemia, lymphoma or multiple myeloma. A real game changer, bone marrow transplantation has boosted survival rates for some blood cancers from nearly zero to over 85%.

Unfortunately, however, patients receiving bone marrow transplants are at high risk of developing Graft versus Host Disease (GvHD), a life-threatening complication that occurs when the transplanted cells from the donor the graft identify the transplant recipient the host as foreign.

This triggers an immune reaction that can wreak havoc in the transplanted patients body as it is attacked by the donated cells. This can occur from just days (in the case of acute GvHD) up to months or years (for chronic GvHD) after the haematopoietic cell transplantation (HCT) procedure has taken place.

The mortality rate of acute GvHD is very high in the case of grade 4 GvHD, it is over 90%. The overwhelmingly positive preliminary response of patients to CBD in preventing and treating GvHD shown in early trials, could be the key to significantly decreasing the incidence of this terrible condition.

Before we go on, there is a distinction to be made between a transplant rejection, which occurs when the immune system of the transplant recipient rejects the transplanted tissue, as may be the case in liver or heart transplants, and GvHD, which occurs when the while blood cells in the donors reject the recipient.

There are two types of bone marrow transplant: autologous (from the patients own stem cells) and allogeneic (stem cells from a donor). It is in the latter where GvHD may occur.

GvHD from allogeneic bone marrow transplants can manifest itself in many forms and degrees; ranging from mild, moderate or severe, to potentially fatal for the patient. Acute GvHD can cause rashes and blistering of the skin, nausea, vomiting, abdominal cramps accompanied by diarrhoea, jaundice; and may attack the lungs, liver and eyes. It is often associated with chronic illness, infections, disability, reduced quality of life, and is a major cause of morbidity and mortality following HCT.

Researchers estimate that despite aggressive preventive measures with immunosuppressive treatments, 30% to 50% of transplanted patients whose donors were fully matching siblings and 50% to 70% of patients whose donors were unrelated to them develop some level of GvHD.

Though it may sound surprising, currently there are no FDA approved therapies for either the prevention or treatment of acute GvHD.

Enter Kalytera Therapeutics, a clinical-stage pharmaceutical company aiming to develop cannabidiol (CBD) for the treatment of serious diseases. The companys drug development expertise and intellectual property portfolio put it at the forefront in the development of CBD-based medicines for a range of important unmet medical needs. Currently, its resources are being focused mainly on mitigating the effects of GvHD following bone marrow transplantation.

Kalytera Therapeutics lead programme, in which we are evaluating CBD for the prevention and treatment of GvHD, is in late-stage clinical testing. Kalytera Therapeutics have an ongoing open label Phase 2 clinical study to evaluate the pharmacokinetic profile, safety and efficacy of CBD for the prevention of acute GvHD with encouraging preliminary results; we are currently approaching the end of cohort 2. A series of Phase 1 studies requested by the FDA, such as the effect of food intake on the absorption of oral CBD, have also been completed.

At this stage, Kalytera Therapeutics are ready to plan a meeting with the FDA to discuss the possibility of starting a pivotal study later this year. Following the approval of Epidiolex for Dravet Syndrome by GW Pharma, the FDA has encouraged that Kalytera apply for a 505(b)2 regulatory pathway, which provides manufacturers of some types of drugs to apply for FDA approval without performing all the work required in a new drug application.

Kalytera Therapeutics have also received a Fast Track Designation to aid in the development and expedite review of drugs intended for serious or life-threatening disease and addressing an unmet medical need, for the companys CBD products for prevention and treatment of acute GvHD. This could accelerate the approval process for these products.

The obvious first step in attempting to prevent GvHD is to find donor cells that match the genetics of the immune system of the transplant recipient as closely as possible. But even in the ideal case of the donors being a sibling, the patient still must rely on drugs specially developed to cause immunosuppression of the donor cells, through either T-cell depletion or drugs. Treatments usually used for this include methotrexate, cyclosporine, tacrolimus, sirolimus, mycophenolate mofetil and antithymocyte globulin (ATG), as determined by each medical team and institution.

When it comes to treating GvHD, the grafts immune cell activation needs to be suppressed with medication, so that donor-host immune tolerance can be established once again. Most patients are given corticosteroids, which directly suppress the donors immune cell attack on the hosts tissues. This also raises the risk of infection and the relapse of cancer.

As of now, there are guidelines but there is no standard treatment for either prevention or treatment of acute GvHD. Only 30% to 50% of patients with moderate to severe GvHD respond to corticosteroids, leaving many at risk of fatal outcomes. Everyone in the healthcare system should be aware that more research is necessary to discover better treatment options to reduce the rates of mortality and morbidity in transplantation patients.

The programme Kalytera is now implementing is based on previous Phase 2a clinical trials, which showed outstanding preliminary results in the prevention of the disease by giving patients CBD orally. In the first study, 48 patients received CBD for seven days prior to the bone marrow transplant procedure and for 30 days thereafter, as opposed to a group of 101 historical controls who had been given the usual GvHD prophylaxis and treated in the same BMT unit by the same medical team.

Remarkably, results showed none of the 48 patients had developed acute GvHD in the 30 days of treatment with CBD. Those who developed GvHD did so within a median time of 60 days, whereas the control group of 101 historical controls began to develop acute GvHD in a median time of 20 days only (ranging from nine to 137).

In the CBD treated group, the rates of grade 2 to grade 4 acute GvHD by day 100 were 12.1%, compared with 46% in the control. The rate of severe grade 3 to grade 4 was 5%, compared to 10% in the control. Equally important is the finding that CBD was also safe and well tolerated, with no severe adverse events attributed to its consumption. This is consistent with safety data previously reported on CBD administered to humans, even with three to four times higher doses and even when taken over extended periods of time.

In light of these encouraging initial results, it was decided to test the efficacy of a prolonged treatment covering 100 days: the time window in which acute GvHD usually occurs. In a second study, 12 patients were administered CBD at the same dose starting from seven days before the bone marrow transplant procedure until 100 days post-transplantation. No safety issues were observed here either and only one noncompliant patient, representing 8% of the CBD treatment group, developed acute GvHD; compared to a 46% incidence at the same institution in the historical group of 101 patients described above. This is despite the fact that the majority of the patients (10 out of 12) received stem cells from unrelated donors, including five patients who received stem cells from non-fully matched donors, which would normally increase their chance of developing GvHD.

In a third Phase 2a study, which was performed for treatment of already sick patients, 10 patients with acute GvHD, who were refractory to standard treatment with high dose steroids (only 60% of patients respond to first line therapy with high dose steroids), were administered daily doses of CBD for up to three months. Strikingly, nine of the 10 patients enrolled in the study responded to treatment, seven of them achieving complete remission of GvHD and two more achieving a near-complete response.

These results are impressive when we take into account that the 12-month mortality rate among patients with grade 3 and grade 4 GvHD who do not respond to steroids exceeds 60% and 80%, respectively. Indeed, these preliminary results compare favourably with the results of the historical control group of 29 patients with steroid-refractory grades 3 and 4 GvHD, among which 26 patients died from GvHD and its complications.

With a median follow-up period of 13 months, six patients were still alive. Two patients died from leukaemia relapses, and two patients died from GvHD-related infectious complications. No patient deaths were determined to be associated with CBD treatment. This underlines the urgency of developing a product that can prevent and treat GvHD.

On the list of the 10 most expensive medical procedures, allogeneic BMT ranked fourth; while autologous BMT, at less than half the outrageous cost, still made it to the eighth place. Depending on the country and institution, costs range from tens of thousands to hundreds of thousands of dollars per procedure. The need and incentive to increase the rate of success are indisputable.

The life-saving ability of Kalyteras CBD products for the prevention and treatment of acute GvHD, currently classified as an orphan disease, means the company has good chances of obtaining premium pricing for a course of treatment. Over 20,000 patients suffer from acute GvHD following bone marrow transplantation in the six major markets of the US, Germany, the UK, France, Spain and Japan every year.

According to the January 2018 Market Forecast Report by DelveInsight Perspective, the potential market for a successful drug for prevention and treatment of GvHD in the seven major jurisdictions of the US, Germany, France, Italy, Spain, the UK and Japan is estimated to be over $408m in 2018; and could grow to approximately $1.3bn by 2027.

Once Kalyteras CBD products are approved by the FDA, the company believes that treating physicians would not be expected to prescribe anything other than its approved formulation of CBD (as opposed to a non-approved CBD that might be available online or from other commercial sources), especially since patients are often in isolation in the intensive care unit. It is safe to assume that neither private insurance nor government provided healthcare reimbursement would be available for non-prescription generic CBD in the jurisdictions where Kalytera intends to market its CBD product.

Conducting proper, large scale clinical trials with CBD is of utmost importance. Although in some areas CBD seems to be generally safe in the broader healthy population, it can be harmful to some groups, such as young adults, women of childbearing age, pregnant women, children, people with known heart conditions or low blood pressure, and the elderly.

Despite all the hype about the multiple health benefits of cannabis-based products trumpeted by many (though not clearly stated due to possible risks of liabilities for unsubstantiated claims), so far only one CBD-based drug has received FDA approval for the treatment of two rare and serious types of epilepsy.

Contrary to popular belief and anecdotal evidence, CBD is not a biologically inert compound. Rather, CBD has a complex pharmacokinetic and pharmacodynamic profile similar to any other medication with the potential to interact with other medications and medical conditions. CBD is metabolised in the liver by enzymes responsible for metabolising a large percentage of other drugs. When taken concomitantly, CBD may reduce or neutralise the intended action of those other medications. Kalytera has completed drug to drug interaction testing in vitro and is now planning to start testing in healthy subjects.

CBD oil can have negative side effects too, such as drowsiness, drop in blood pressure when taken in large doses, being potentially harmful for people with low blood pressure. Other problems are dizziness or light-headedness, appetite changes, diarrhoea, hormonal changes, hypokinesia and resting tremor when used for epilepsy. In psychotic disorders it has side effects too, but they are milder than on other drugs used until today. It can benefit some Parkinsons patients, but not all of them.

Kalytera has a solid, experienced leadership team and very strong intellectual property portfolio. We have three issued US and European patents covering the use of CBD in the prevention and treatment of GvHD, as well as four orphan drug designations for the treatment and prevention of GvHD in the US and Europe.

Our promising preliminary results indicate we will be able to help BMT patients and their donated bone marrow get along better. This will greatly improve patients quality of life, productivity and life expectancy by keeping them GvHD free.

Global Stem Cell Therapy Market: Overview

Also called regenerative medicine, stem cell therapy encourages the reparative response of damaged, diseased, or dysfunctional tissue via the use of stem cells and their derivatives. Replacing the practice of organ transplantations, stem cell therapies have eliminated the dependence on availability of donors. Bone marrow transplant is perhaps the most commonly employed stem cell therapy.

Osteoarthritis, cerebral palsy, heart failure, multiple sclerosis and even hearing loss could be treated using stem cell therapies. Doctors have successfully performed stem cell transplants that significantly aid patients fight cancers such as leukemia and other blood-related diseases.

Global Stem Cell Therapy Market: Key Trends

The key factors influencing the growth of the global stem cell therapy market are increasing funds in the development of new stem lines, the advent of advanced genomic procedures used in stem cell analysis, and greater emphasis on human embryonic stem cells. As the traditional organ transplantations are associated with limitations such as infection, rejection, and immunosuppression along with high reliance on organ donors, the demand for stem cell therapy is likely to soar. The growing deployment of stem cells in the treatment of wounds and damaged skin, scarring, and grafts is another prominent catalyst of the market.

On the contrary, inadequate infrastructural facilities coupled with ethical issues related to embryonic stem cells might impede the growth of the market. However, the ongoing research for the manipulation of stem cells from cord blood cells, bone marrow, and skin for the treatment of ailments including cardiovascular and diabetes will open up new doors for the advancement of the market.

Global Stem Cell Therapy Market: Market Potential

A number of new studies, research projects, and development of novel therapies have come forth in the global market for stem cell therapy. Several of these treatments are in the pipeline, while many others have received approvals by regulatory bodies.

In March 2017, Belgian biotech company TiGenix announced that its cardiac stem cell therapy, AlloCSC-01 has successfully reached its phase I/II with positive results. Subsequently, it has been approved by the U.S. FDA. If this therapy is well- received by the market, nearly 1.9 million AMI patients could be treated through this stem cell therapy.

Another significant development is the granting of a patent to Israel-based Kadimastem Ltd. for its novel stem-cell based technology to be used in the treatment of multiple sclerosis (MS) and other similar conditions of the nervous system. The companys technology used for producing supporting cells in the central nervous system, taken from human stem cells such as myelin-producing cells is also covered in the patent.

Stem Cell Therapy Market to Witness Growth Acceleration During 2017 2025 - Daily Science

Skin Stem Cells Comments Off on Stem Cell Therapy Market to Witness Growth Acceleration During 2017 2025 – Daily Science | March 28th, 2020

During this process the cells not only shed any memories of their previous identities, but they revert to a younger state. They accomplish this transformation by wiping their DNA clean of the molecular tags that not only differentiate, say, a skin cell from a heart muscle cell, but of other tags that accumulate as a cell ages.

Recently researchers have begun to wonder whether exposing the adult cells to Yamanaka proteins for days rather than weeks could trigger this youthful reversion without inducing full-on pluripotency. In fact, researchers at the Salk Institute for Biological Studies found in 2016 that briefly expressing the four Yamanaka factors in mice with a form of premature aging extended the animals life span by about 20%. But it wasnt clear whether this approach would work in humans.

Sarkar and Sebastiano wondered whether old human cells would respond in a similar fashion, and whether the response would be limited to just a few cell types or generalizable for many tissues. They devised a way to use genetic material called messenger RNA to temporarily express six reprogramming factors the four Yamanaka factors plus two additional proteins in human skin and blood vessel cells. Messenger RNA rapidly degrades in cells, allowing the researchers to tightly control the duration of the signal.

The researchers then compared the gene-expression patterns of treated cells and control cells, both obtained from elderly adults, with those of untreated cells from younger people. They found that cells from elderly people exhibited signs of aging reversal after just four days of exposure to the reprogramming factors. Whereas untreated elderly cells expressed higher levels of genes associated with known aging pathways, treated elderly cells more closely resembled younger cells in their patterns of gene expression.

When the researchers studied the patterns of aging-associated chemical tags called methyl groups, which serve as an indicator of a cells chronological age, they found that the treated cells appeared to be about 1 to 3 years younger on average than untreated cells from elderly people, with peaks of 3 years (in skin cells) and 7 years (in cells that line blood vessels).

Next they compared several hallmarks of aging including how cells sense nutrients, metabolize compounds to create energy and dispose of cellular trash among cells from young people, treated cells from old people and untreated cells from old people.

We saw a dramatic rejuvenation across all hallmarks but one in all the cell types tested, Sebastiano said. But our last and most important experiment was done on muscle stem cells. Although they are naturally endowed with the ability to self-renew, this capacity wanes with age. We wondered, Can we also rejuvenate stem cells and have a long-term effect?

When the researchers transplanted old mouse muscle stem cells that had been treated back into elderly mice, the animals regained the muscle strength of younger mice, they found.

Finally, the researchers isolated cells from the cartilage of people with and without osteoarthritis. They found that the temporary exposure of the osteoarthritic cells to the reprogramming factors reduced the secretion of inflammatory molecules and improved the cells ability to divide and function.

The researchers are now optimizing the panel of reprogramming proteins needed to rejuvenate human cells and are exploring the possibility of treating cells or tissues without removing them from the body.

Although much more work needs to be done, we are hopeful that we may one day have the opportunity to reboot entire tissues, Sebastiano said. But first we want to make sure that this is rigorously tested in the lab and found to be safe.

Old human cells rejuvenated with stem cell technology - Stanford Medical Center Report

A study published in STEM CELLS Translational Medicine, by researchers at The Baker Institute for Animal Health, at Cornell's College of Veterinary Medicine, demonstrates for the first time that mesenchymal stromal cells (MSCs) are an effective weapon against bacteria in biofilm.

DURHAM, N.C., March 26, 2020 /PRNewswire-PRWeb/ -- Researchers have potentially made a breakthrough in the war on antibiotic-resistant superbugs including MRSA, which kills an estimated 20,000 people in the United States alone each year with a new discovery whose details are published today in STEM CELLS Translational Medicine. The study, by researchers at The Baker Institute for Animal Health, at Cornell's College of Veterinary Medicine, demonstrates for the first time that mesenchymal stromal cells (MSCs) are an effective weapon against bacteria in biofilm.

Biofilms are thin, slimy films made up of bacteria that can attach to skin wounds, teeth and other surfaces, creating the opportunity for infections to flourish. These highly structured cellular communities offer bacteria shelter from harmful factors, helping them resist antibiotics, mutate rapidly and evade the immune system.

"MSCs help kill the bacteria through the secretion of enzymes, called proteases, that break the peptide bonds of proteins and cause biofilm to destabilize. This in turn increases the effectiveness of antibiotics that previously weren't working, as the bacteria are no longer being protected by the biofilm," explained Gerlinde R. Van de Walle, DVM, Ph.D., who led the study along with Charlotte Marx, DVM, Ph.D.

Other recent studies, including one by the Cornell team, have shown that MSCs can inhibit the growth of bacteria associated with chronic infections by secreting antimicrobial peptides. "But these studies were conducted primarily on planktonic bacteria, which are individually floating bacteria cells. Thus, information on the effects on biofilms was largely lacking," Dr. Marx said.

The current study explores how MSC secretome, delivered as conditioned medium, performs against various wound-related bacterial pathogens. It also looks at the mechanisms that affect bacterial biofilms. The experiments were performed in vitro, using equine MSC. "We use equine MSC in our work since the horse represents a physiologically relevant model for human wound healing and offers a readily translatable model for MSC therapies in humans," Dr. Van de Walle explained.

The researchers began by showing that equine MSC secretome inhibits the growth of four types of planktonic bacteria that commonly colonize skin wounds. Encouraged by the results, they next sought to determine the effect of the MSC secretome on these same bacterial strains in biofilms, which is the predominant way bacteria invade wounds. They looked at how the MSCs affected biofilm formation, then repeated the experiments on biofilms that were already established. Finally, they turned their attention to the bacteria strain responsible for MRSA.

Dr. Marx reported the results. "Our salient findings," she said, "were that factors secreted by equine MSC impaired both planktonic and biofilms including MRSA as well as disrupted mature biofilms generated by these bacteria. Importantly, we found that these effects resulted from a protease-dependent mechanism."

Dr. Van de Walle added, "We also found that MSC-secreted factors allowed previously ineffective antibiotic treatments to become more effective at reducing bacterial survival. In light of the rise of antibiotic-resistant bacterial strains as an increasing global health threat, our findings provide the rationale for using the MSC secretome as a complementary treatment for bacterial infections."

"Outcomes from this study highlight for the first time that the secretome from mesenchymal stem cells significantly reduces the formation of bacterial infections, including the antibiotic resistant MRSA," said Anthony Atala, M.D., Editor-in-Chief of STEM CELLS Translational Medicine and director of the Wake Forest Institute for Regenerative Medicine. "Antibiotic resistance has long been a concern and this research highlights some promising new tactics."

Study offers potential breakthrough in the war on antibiotic-resistant superbugs - Yahoo Finance

Skin Stem Cells Comments Off on Study offers potential breakthrough in the war on antibiotic-resistant superbugs – Yahoo Finance | March 26th, 2020

GOLDEN, CO / ACCESSWIRE / March 26, 2020 / Vitro Diagnostics, Inc. (VODG), dba Vitro Biopharma, announced its 1st quarter ended January 31st, 2020 financial results of operations.

Vitro Diagnostics Inc. ("Vitro Biopharma") is pleased to announce a record 1st comparative quarter in Total Revenues. Vitro Biopharma recorded 1st quarter revenues of $225,921 vs $192,895 an increase of 17% over the same comparative quarter last year. In addition, Stem Cell treatments accounted for 74% of the revenues up from 71% of the revenues in the prior comparative quarter last year. Current quarter stem cell revenues were $167,750 for the 1st quarter ended January 31, 2020 vs $137,123 for the first quarter ended January 31, 2019.

The company's gross profit margins improved to 75% up from 73% in the comparative prior year's quarter. Gross margin improvement is in line with the strategic direction of the company to expand the market of its flagship product AlloRx Stem Cells. The company's clean-room lab expansion last year and expanded Stem Cell manufacturing using its patent-pending cell line, has increased efficiencies and lowered production costs.

Overall operating expenses increased in the quarter to $193,385 from $147,398 in the prior year's comparative quarter. The increase in expenses reflects additional investment as the Company expands its capability to service its strategic direction of offshore Stem Cell treatments while also expanding into US markets. The company expended additional resources on external consultants supporting our regulatory status in maintaining ISO9001 & ISO13485 certifications, expanding our efforts to approach US markets through FDA filings and advancement of existing patent filings.

The company's first quarter is its most seasonal quarter as the period between Thanksgiving and the New Year is slow for all the company's revenue lines of Nutra Vivo/STEMulize, AlloRx Stem Cells, private labeled InfiniVive-MD Stem Cell Serum and our core research products.

During the quarter the company achieved and pursed the following company objectives

During the quarter the company commenced a Series A Convertible Preferred Stock offering to accredited investors under the SEC Regulation D exemption. The preferred Stock is priced at $25 per share which is convertible at $0.25 cents per share for a total of 100 shares. The minimum investment is $50,000 per unit. The company sold $450,000 of the Series A Convertible Preferred Stock during the quarter. The company has additional interest in the offering and subsequent to the quarter has sold an additional $50,000 unit for a total to date of $500,000. The company has additional interested parties for approximately $200,000. The offering is for a total of $1,000,000.

Our partnership with DVC. Stem in the Cayman Islands continued to advance through treatment of new & previous patients. This IRB-approved protocol targets patients with inflammatory conditions including multiple sclerosis, systemic inflammation and new indications including Chrohn's disease, Alzheimer's disease and COPD. To date we have treated 60 patients including repeat treatments. There have been no serious adverse events and we continue to gain evidence of efficacy. One of the initial MS patients has now received a second transplant of our AlloRx Stem Cells and he has reported significant therapeutic benefits of both the initial and subsequent therapy. He had received an earlier transplant of adipose-derived MSCs that was effective, but the improvement lasted 3 months while AlloRx Stem Cell therapy lasted 18 months. We had predicted such a clinical outcome based on significantly higher potency of umbilical cord MSCS compared to those derived from adipose tissue or bone marrow. The Chrohn's disease patient showed significant improvement as did both the AD & COPD patients.

The strategic development of our stem cell therapies involves pursuit of both offshore and domestic markets. The partnership with DVC Stem, our IRB-approved trial in the Bahamas together with other strategic opportunities represent offshore operations & prospects. During Q1 2020, we initiated expansion into US therapeutic markets through development of an Investigational New Drug (IND) application for submission to FDA. Once approved, an IND allows the conduct of clinical trials for specific medical conditions in the US.

Story continues

Given the current COVID-19 pandemic, our initial IND application is for use of AlloRx Stem Cells in treatment of Coronavirus infections. This is supported by clinical studies showing that 17 critically ill patients responded favorably to IV infusion of umbilical cord-derived MSCs. All patients were receiving assisted ventilation but 3 days following stem cell therapy, were removed from ventilators and subsequently discharged from the hospital. We are pursuing discussions with FDA to establish the appropriate regulatory pathway and expedited review options given the current emergency circumstances. (See Subsequent Events, below, for additional discussion of our COVID-19 response.) Once our initial IND is in place, we have plans for additional INDs for stem cell therapy of musculoskeletal conditions and Alzheimer's disease.

We have received an initial order of AlloRx Stem Cells for testing purposes by PR Medica located in Cabo San Lucas. Given successful test results, we anticipate subsequent new revenue generation from this customer.

Vitro Biopharma's cosmetic topical stem cell serum is being distributed by InfiniVive MD into cosmetic clinics that are providing the topical treatment as a beautification product. To date the company's product is being offered in 10 cosmetic clinics.

Our partner, Dr Jack Zamora, MD was a keynote speaker at a master session at the American Academy of Cosmetic Surgery annual meeting in late February. The topic of his presentation was "Topical Stem Cells, Exosomes and Conditioned Media Serums in Aesthetics." This was the official launch of the InfiniVive-MD platform including: Dailey Serum, Stem Cell Serum 2.0 & Exosomes within the product line. Vitro Biopharma will manufacture & private label these new products for distribution in the US. We anticipate InfiniVive MD growth, development and revenues to mirror the development of Apyx subdermal plasma skin tightening as a cosmetic treatment and technique that has gone global.

http://www.jackzamoramd.com http://www.infinivivemd.com

Our core research product sales continued to expand in Q1 2020. Our facility expansion continued with addition of manufacturing capacity and development of plans to add operational facility to increase outputs further by 100% or more. We were also in discussions with the USPTO regarding our pending patents for our novel stem cell therapy and stem cell activation technology. We continue to work closely with our examiner and have established communication channels to facilitate awards of these patents.

The COVD-19 pandemic is a significant obstacle for all business. However, Vitro Biopharma is uniquely positioned since we have a potential effective therapy. This is based on 3 independent reports showing efficacy of stem cell therapy in 17 COVID-19 patients. All were treated with IV umbilical cord MSCs comparable to AlloRx Stem Cells and all 17 required respiratory assistance but within 3-4 days of treatment, were able to breath without ventilators and were discharged within 14 days. https://www.scmp.com/news/china/society/article/3053080/coronavirus-critically-ill-chinese-patient-saved-stem-cell On the contrary, untreated patients on ventilators have death rates of 50% or more. We have received a formal request to supply AlloRx Stem Cells for compassionate use from a major university medical center and several other potential clinical partners have also expressed interest in using our cells to treat COVID-19 patients. We are presently working with the FDA to gain authority to begin clinical testing in the US. We are currently assessing the overall financial impact of the COVID-19 pandemic on our business, but this depends on overall control of the pandemic. There have been no staff layoffs and our workers are considered essential since we conduct essential research to the COVID-19 response.

Dr. Jim Musick, CEO of Vitro Biopharma, said, "We are very pleased with the increased revenue growth during our first quarter 2020 compared to the prior year However all our resources are currently focused on the emergency response to the COVID-19 pandemic and increasing our inventory of AlloRx to satisfy anticipated emergency demand to treat critically ill COVID-19 patients." The Company is working to get expedited clinical trial approvals to sell our AlloRx Stem Cells to hospitals coping with the pandemic. Vitro is pleased to have recently been recognized by Bioinformant as "a Company Tracking the Coronavirus". https://bioinformant.com/product/coronavirus-covid-19-report/ We anticipate clinical progress in the effectiveness of our stem cell therapies while expecting to see a reduction in our offshore and cosmetic revenues for the next quarter or two. The company is in a good cash position to weather this storm and simultaneously advance its AlloRx stem cell therapies into clinical trials.

In summary, Vitro Biopharma is advancing as a key player in regenerative medicine with 10- years' experience in the development and commercialization of stem cell products for research, recognized by a Best in Practice Technology Innovation Leadership award for Stem Cell Tools and Technology and a growing track record of successful translation to therapy. We are leveraging our proprietary technology platform to the establishment of international Stem Cell Centers of Excellence and regulatory approvals in the US and worldwide.

Sincerely yours,

James R. Musick, PhD.President, CEO & Chairman of the Boardwww.vitrobiopharma.com

In severe cases, it can also cause deadly hardening of internal organs like the lungs

MADISON, Wis. A year ago, Chuck Beschta couldn't walk more than a few minutes without stopping to rest.

"Just going out and doing normal activities outside raking the lawn mowing the grass shoveling the driveway whatever;snow blowing, those became impossible."

After months of testing he was diagnosed with severe scleroderma, which was hardening his skin but even worse. it was hardening his lungs, making it hard to breathe.

Scleroderma is an autoimmune rheumatic disease where an overproduction of collagen produced in the body tissues.

But in severe cases, it can also cause deadly hardening of internal organs like the lungs, giving some patients little hope of surviving.

Chuck's case was getting more dire.

"He was getting worse despite the best therapy we had to offer," explained Dr. Kevin McKown, a rheumatologist at the University of Wisconsin Hospital in Madison

Dr. McKown recommended a stem cell transplant newly approved for scleroderma to reboot chucks immune system.

"There's a process by which they try to remove the autoreactive immune cells, the cells that are caught in the immune process and then they infuse that back in and hope that the body will basically take up and graft that immune system

Rheumatologists at University of Wisconsin Health tested the treatment since they have already been conducting bone marrow transplants for decades.

Surgeons take out a sample of the patient's bone marrow, isolate the stem cells, and use radiation and chemotherapy to clean out their immune system. The same stem cells are later injected back into the patient's immune system with the hope that new cells will grow and the system is rid of the bad ones.

The process is dangerous when the cells are taken out because the patient's immune system is more vulnerable, making infections more likely to occur.

Chuck saw almost immediate results. His skin was softer and his breathing improved.

He hopes his scleroderma has been cured.

"I think we can be optimistic and so far the people who have been followed out as far as 10 years out don't seem to be getting it back," said Dr. McKown.

After four and a half years, 79% of patients who underwent the treatment were alive without serious complications compared to 50% that were treated with the original drugs.

Without a transplant, less than half the patients, like Chuck, who have diffuse scleroderma and severe lung disease live 10 years past diagnosis. stem cell transplants are commonly used to treat leukemia and lymphoma, cancers that affect the blood and lymphatic system.
