University of Pennsylvania: Deconstructing the mechanics of bone marrow disease | India Education – India Education Diary

By daniellenierenberg

Fibrosis is the thickening of various tissues caused by the deposition of fibrillar extracellular matrix (ECM) in tissues and organs as part of the bodys wound healing response to various forms of damage. When accompanied by chronic inflammation, fibrosis can go into overdrive and produce excess scar tissue that can no longer be degraded. This process causes many diseases in multiple organs, including lung fibrosis induced by smoking or asbestos, liver fibrosis induced by alcohol abuse, and heart fibrosis often following heart attacks. Fibrosis can also occur in the bone marrow, the spongy tissue inside some bones that houses blood-producing hematopoietic stem cells (HSCs) and can lead to scarring and the disruption of normal functions.

Chronic blood cancers known as myeloproliferative neoplasms (MPNs) are one example, in which patients can develop fibrotic bone marrow, or myelofibrosis, that disrupts the normal production of blood cells. Monocytes, a type of white blood cell belonging to the group of myeloid cells, are overproduced from HSCs in neoplasms and contribute to the inflammation in the bone marrow environment, or niche. However, how the fibrotic bone marrow niche itself impacts the function of monocytes and inflammation in the bone marrow was unknown.

Now, a collaborative team from Penn, Harvard, the Dana-Farber Cancer Institute (DFCI), and Brigham and Womens Hospital has created a programmable hydrogel-based in vitro model mimicking healthy and fibrotic human bone marrow. Combining this system with mouse in vivo models of myelofibrosis, the researchers demonstrated that monocytes decide whether to enter a pro-inflammatory state and go on to differentiate into inflammatory dendritic cells based on specific mechanical properties of the bone marrow niche with its densely packed ECM molecules. Importantly, the team found a drug that could tone down these pathological mechanical effects on monocytes, reducing their numbers as well as the numbers of inflammatory myeloid cells in mice with myelofibrosis. The findings are published in Nature Materials.

We found that stiff and more elastic slow-relaxing artificial ECMs induced immature monocytes to differentiate into monocytes with a pro-inflammatory program strongly resembling that of monocytes in myelofibrosis patients, and the monocytes to differentiate further into inflammatory dendritic cells, says co-first author Kyle Vining, who recently joined Penn. More viscous fast-relaxing artificial ECMs suppressed this myelofibrosis-like effect on monocytes. This opened up the possibility of a mechanical checkpoint that could be disrupted in myelofibrotic bone marrow and also may be at play in other fibrotic diseases. Vining will be appointed assistant professor of preventive and restorative sciences in the School of Dental Medicine and the Department of Materials Sciences in the School of Engineering and Applied Science, pending approval by Penn Dental Medicines personnel committees and the Provosts office.

Vining worked on the study as a postdoctoral fellow at Harvard in the lab of David Mooney. Our study shows that the differentiation state of monocytes, which are key players in the immune system, is highly regulated by mechanical changes in the ECM they encounter, says Mooney, who co-led the study with DFCI researcher Kai Wucherpfennig. Specifically, the ECMs viscoelasticity has been a historically under-appreciated aspect of its mechanical properties that we find correlates strongly between our in vitro and the in vivo models and human disease. It turns out that myelofibrosis is a mechano-related disease that could be treated by interfering with the mechanical signaling in bone marrow cells.

Mooney is also the Robert P. Pinkas Family Professor of Bioengineering at Harvard and leads the Wyss Institutes Immuno-Materials Platform. Wucherpfennig is director of DFCIs Center for Cancer Immunotherapy Research, professor of neurobiology at Brigham and Harvard Medical School, and an associate member of the Broad Institute of MIT and Harvard. Mooney, together with co-senior author F. Stephen Hodi, also heads the Immuno-engineering to Improve Immunotherapy (i3) Center, which aims to create new biomaterials-based approaches to enhance immune responses against tumors. The new study follows the Centers road map. Hodi is director of the Melanoma Center and The Center for Immuno-Oncology at DFCI and professor of medicine at Harvard Medical School.

Gleaning mechanical bone marrow failureThe mechanical properties of most biological materials are determined by their viscoelastic characteristics. Unlike purely elastic substances like a vibrating quartz, which store elastic energy when mechanically stressed and quickly recover to their original state once the stress is removed, slow-relaxing viscoelastic substances also have a viscous component. Like the viscosity of honey, this allows them to dissipate stress under mechanical strain by rapid stress relaxation. Viscous materials are thus fast-relaxing materials in contrast to slow-relaxing purely elastic materials.

The team developed an alginate-based hydrogel system that mimics the viscoelasticity of natural ECM and allowed them to tune the elasticity independent from other physical and biochemical properties. By tweaking the balance between elastic and viscous properties in these artificial ECMs, they could recapitulate the viscoelasticity of healthy and scarred fibrotic bone marrow, whose elasticity is increased by excess ECM fibers. Human monocytes placed into these artificial ECMs constantly push and pull at them and in turn respond to the materials mechanical characteristics.

Next, the team investigated how the mechanical characteristics of stiff and elastic hydrogels compared to those in actual bone marrow affected by myelofibrosis. They took advantage of a mouse model in which an activating mutation in a gene known as Jak2 causes MPN, pro-inflammatory signaling in the bone marrow, and development of myelofibrosis, similar to the disease process in human patients with MPN. When they investigated the mechanical properties of bone marrow in the animals femur bones, using a nanoindentation probe, the researchers measured a higher stiffness than in non-fibrotic bone marrow. Importantly, we found that the pathologic grading of myelofibrosis in the animal model was significantly correlated with changes in viscoelasticity, said co-first author Anna Marneth, who spearheaded the experiments in the mouse model as a postdoctoral fellow working with Ann Mullally, a principal investigator at Brigham and DFCI, and another senior author on the study.

Targeting dysregulated bone marrow mechanicsAn important question was whether monocytes response to the mechanical impact of the fibrotic bone marrow niche could be therapeutically targeted. The researchers focused on an isoform of the phosphoinositide 3-kinase (PI3K)-gamma protein, which is specifically expressed in monocytes and closely related immune cells. PI3K-gamma is known for regulating the assembly of a cell-stiffening filamentous cytoskeleton below the cell surface that expands in response to mechanical stress, which the team also observed in monocytes encountering a fibrotic ECM. When they added a drug that inhibits PI3K-gamma to stiff elastic artificial ECMs, it toned down their pro-inflammatory response and, when given as an oral treatment to myelofibrosis mice, significantly lowered the number of monocytes and dendritic cells in their bone marrow.

This research opens new avenues for modifying immune cell function in fibrotic diseases that are currently difficult to treat. The results are also highly relevant to human cancers with a highly fibrotic microenvironment, such as pancreatic cancer, says Wucherpfennig.

How long-term Covid-19 immunity paves the way for universal Covid-19 vaccines – Vox.com

By daniellenierenberg

This week, the White House held a summit on the future of Covid-19 vaccines that brought together scientists and vaccine manufacturers to discuss new vaccine technologies. Officials said that new vaccines are an urgent priority as US Covid-19 cases and hospitalizations are rising once again, vaccination rates are hitting a plateau, Covid-19 funding is running low, and the virus itself is continuing to mutate.

But in recent months, scientists have also learned that the immune cells that provide lasting protection known as memory B cells and T cells can keep the worst effects of the most recent versions of the virus at bay, even if they were trained to corral older strains of SARS-CoV-2. Vaccine researchers are expanding their focus from antibodies to these memory immune cells as the new discoveries open a path toward universal coronavirus vaccines.

Universal vaccines, however, are still a long way off possibly years drawing on approaches never used before. Thats a scientific challenge, said Anthony Fauci, chief medical adviser to the president, during the summit.

The good news is that far fewer people are dying from the disease compared to the wave of cases this past winter spurred by the omicron variant of SARS-CoV-2, the virus that causes Covid-19. The first round of Covid-19 vaccines is still holding death rates down to around 360 per day, according to the Centers for Disease Control and Prevention. Still, health officials want to do better.

While the vaccines are terrific, hundreds of Americans, thousands of people around the world are still dying every day, Ashish Jha, the White House Covid-19 response coordinator, said Tuesday. Building a new generation of vaccines will make an enormous difference to bringing this pandemic to an end.

The National Institutes of Health is already funding several research teams developing Covid-19 vaccines that elicit protection against many different versions of the virus, shield against future changes to the virus before they arise, and protect against other coronaviruses.

From there, health officials are aiming not just to develop vaccines that provide more durable protection against a wider array of threats, but also rethinking the vaccination strategy overall. With a better understanding of long-term immunity, more robust vaccines, and a comprehensive public health approach, health officials say they have a better shot at restoring normalcy.

Much of the discussion around vaccines and immunity to Covid-19 centers on antibodies, proteins produced by the immune system that attach to the virus. And indeed, they are important.

Antibodies that prevent the virus from causing an infection in the first place are called neutralizing antibodies. A high concentration of antibodies in the body that blocks SARS-CoV-2 is a key indicator of good protection against reinfection. Antibodies can also serve as a way to mark intruders so that other immune system cells can dispose of them.

But making large quantities of antibodies takes a lot of resources from the body, so their production tapers off with time after an infection or a vaccination. Another concern is that antibodies are very particular about where they attach to the virus. If the virus has a mutation at that attachment site called an epitope antibodies have a harder time recognizing the pathogen. Thats why some antibody-based treatments for Covid-19 are a lot less effective at stopping the omicron subvariants.

Fortunately, the immune system has other tools in its chest. Inside bone marrow lie stem cells that differentiate to become B cells and T cells. Together, they form the core of the adaptive immune system, which creates a tailored response to threats. After a virus invades a cell, it hijacks its machinery to make copies of itself. White blood cells known as cytotoxic T cells, a.k.a. killer T cells, can identify the wayward cell and make it self-destruct. This mechanism doesnt prevent infections, but it stops them from growing out of control.

Another type of T cell, called a helper T cell, acts as an on switch for B cells, which are the cells that manufacture antibodies. After an infection is extinguished, some T cells and B cells turn into memory cells that stick around in parts of the body, ready to rev up if a virus dares to show up again.

So far, the adaptive immune system seems to hold up pretty well. The first round of Covid-19 vaccines was targeted against the earliest versions of the virus, so plenty of vaccinated people have had breakthrough infections, especially from the newer variants. But only a tiny fraction of those immunized have fallen severely ill or have died.

That likely means that their immune systems couldnt keep the virus out entirely, but their immune cells were able to spool up once an infection took root.

Someones neutralizing antibodies may not be up to the task, but if they have the T cell response, that may make all the difference with severe disease, said Stephen Jameson, a professor of microbiology and immunology at the University of Minnesota.

In just the past year, many studies have borne out the significance of memory B cells and T cells for long-term Covid-19 immunity and answered critical questions about whether they can respond to new variants.

Researchers have found that lower levels of memory B cells were associated with a greater risk of breakthrough infections from the delta variant. On the other hand, B cells induced by Covid-19 vaccines could reactivate months out from the initial vaccine doses to churn out antibodies.

Similarly, scientists found that T cells generated by vaccines were able to recognize SARS-CoV-2 variants like omicron months later. These data provide reasons for optimism, as most vaccine-elicited T cell responses remain capable of recognizing all known SARS-CoV-2 variants, scientists wrote in a March paper in the journal Cell.

Another study showed that Covid-19 vaccines generated strong T cell memory that protected against the virus even without neutralizing antibodies. I think the immunological memory which is induced by vaccines is pretty good and is actually sustained, said Marulasiddappa Suresh, a professor of immunology at the University of Wisconsin-Madison who co-authored the study, published in the Proceedings of the National Academy of Sciences in May.

Whether this protection will hold up over the course of years remains to be seen. Experiences with past coronaviruses like MERS showed that antibodies to the virus can last for four years. Covid-19, however, is spreading at much higher levels and mutating more than MERS did during its initial outbreak. Future protection against the disease hinges on the immune system as well as how much the virus itself will change, and scientists are closely watching both.

Most vaccines to date are designed to counter one or a handful of versions of a given virus. They present the immune system with a target that allows it to prepare its defenses should the actual virus ever invade.

In the case of Covid-19, most vaccines coach the immune system to target the spike protein of the SARS-CoV-2 virus, which it uses to start the infection process. This helps the immune system generate strong neutralizing antibodies. But the spike protein is one of the fastest mutating parts of the virus, making it a moving target.

The fact that B cells and T cells have managed to hold off newer variants hints that it may be possible to target the virus in other ways. Rather than just making neutralizing antibodies that attach to the spike, the adaptive immune system could also produce non-neutralizing antibodies that bind to other regions of the virus that mutate very little, if at all. While these antibodies may not block an infection from taking root, they may be able to provide more durable protection against severe illness that holds up against future SARS-CoV-2 variants.

Another approach is to present the immune system with a variety of different potential mutations of a virus, allowing white blood cells to prepare a response to a spectrum of threats and fill in the blanks.

Universal vaccines have not been deployed before, so researchers are in uncharted territory, and the shots likely wont be ready ahead of a potential fall spike in Covid-19 cases. But developing such a vaccine could eventually reduce the need for boosters and give health officials a head start on countering future outbreaks.

In the meantime, US health officials are planning to distribute vaccines reformulated to target newer Covid-19 variants by September, but its not clear yet what the optimal strategy will be to deploy them given the wide range of immune protection across the population. Between infections and vaccinations, the majority of people in the country have had some exposure to the virus, granting some degree of protection. And since the adaptive immune response to Covid-19 seems to be robust in most people, it may not be necessary for everyone to get an additional shot.

One option is to seek out those with weaker immune systems for boosters. Researchers have now developed a rapid test to measure T cell responses to Covid-19 that could identify people who are more vulnerable to reinfections or breakthrough infections.

Though vaccines are absorbing the most severe consequences from Covid-19, infections are still proving disruptive. Covid-19 outbreaks are contributing to staffing shortages at hospitals, schools, and airlines, leading to delays and cancellations. And the more the virus spreads, the more opportunities it has to mutate in dangerous ways. Stopping this threat requires limiting infections, which in turn still demands measures like social distancing and wearing face masks.

So as good as the next generation of vaccines may prove to be, they are only one element of a comprehensive public health strategy for containing a disease.

How the Regenerative Properties of Glioblastoma Can Be Terminated – Gilmore Health News

By daniellenierenberg

Glioblastoma multiforme (GBM) or simply glioblastoma, is a type of cancer characterized by the growth of an aggressive neoplasm (tumor) in the brain or spinal cord. This type of cancer often occurs in older adults, although the younger population may also be affected.

Glioblastoma

This cancer type is known to be difficult to treat because of its high tendency to reoccur in patients, even after the combination of the three known procedures to treat cancers: surgery, radiotherapy, and chemotherapy. Glioblastoma has been a thorn in the flesh in the world of medicine amongst all cancer types due to the low survival rate of patients affected by it (average survival of 18 months, with only 5% of patients living up to five years). The following factors make this possible: no specific signs or symptoms are noticed leading to late diagnosis and the ability of the cancer cells to resist treatment procedures (the major factor).

Studies have been ongoing to uncover the mechanism behind this major factor, and it has been revealed that Glioblastoma multiforme contains a functional subset of cells known as glioblastoma stem-like cells (GSCs) which are the brain behind its reoccurrence capacity. The identity of these cells remained hidden until a recent study done by a group of scientists finally uncovered it.

The team found out that these functional subsets of cells can be identified through singular mitochondrial alternative metabolisms. After intensively studying the metabolic reactions of these cells, they developed a tumor model that possessed the features of the GBM cultured in the lab. This way, they discovered that GSCs use these two metabolic reactions alpha-ketoglutarate reductive carboxylation and pyruvate carboxylation within their cells. They also discovered that these reactions are catalyzed by the enzymes isocitrate dehydrogenase and pyruvate carboxylase respectively.

They were able to uncover that their high rate of survival which facilitated the recurrence of the tumor is linked to the pyruvate carboxylation reaction. This discovery is important as it means that doctors may now be able to tackle the reoccurring ability of the tumor effectively.

It has always been known that treating glioblastoma is difficult due to its high recurring ability. However, with the revelation from this study, it is now possible for physicians to come up with more effective treatment procedures that would result in a reduced recurrence of the tumors, and an increased survival rate of patients.

This study raises the hopes of both physicians and patients as it reveals a way to hinder the recurrence of glioblastoma tumors. More research is still ongoing to hasten the innovation of a more effective treatment technique.

Human placental mesenchymal stem cells derived exosomes improved functional recovery via attenuating apoptosis and increasing axonal regeneration…

By daniellenierenberg

Abstract: Background Spinal cord injury (SCI) due to lack of restoration of damaged axons is associated with sensorimotor impairment. This study was focused on using the human Placental mesenchymal stem cells- exosome (hPMSCs- exosomes) in an animal model of severe SCI under a new myelogram protocol to confirm lumbar puncture (LP) injection accuracy and evaluate intrathecal space. Methods Mesenchymal stem cells (MSC) were extracted from human placenta tissue and were characterized. HPMSCs- exosomes were isolated by ultracentrifuge. After creating the severe SCI model, LP injection of exosomes was performed in the acute phase. Myelogram was also employed. The improved functional recovery of the animals in the treatment and control groups was followed by recording movement scores for 6 weeks. Hematoxylin-Eosin (H&E) staining was used to evaluate to detect pathological changes and glial scar size. The Immunohistochemistry (IHC) of GFAP and NF200 factors as well as the apoptosis tunnel test was investigated in the tissue samples from the injury site Results The results demonstrated that the use of the myelogram can be a feasible, appropriate and cost-effective method to confirm the accuracy of therapeutic agents LP injection and examine the subarachnoid space in the model of laboratory animals. Furthermore, intrathecal injection of hPMSCs-exosomes in the acute phase of SCI can improve motor function by attenuating apoptosis of neurons at the site of injury, decreased GFAP expression and increased NF200 in the treatment group, reducing glial scarring, and increasing axonal regeneration. Improving functional recovery by not creating bedsores in the treatment group and preventing hematuria were other effects of the exosome Conclusions In conclusion, the effects of hPMSCs-exosome can be considered to be not only in restoring function but also in preventing complications and managing symptoms. Thus, the neuroregenerative and anti-apoptotic potential of hPMSCs-exosome can be considered a therapeutic approach in SCI reconstructive medicine.

Mustang Bio Announces First Patient Successfully Treated by Ex Vivo Lentiviral Gene Therapy to Treat RAG1 Severe Combined Immunodeficiency – BioSpace

By daniellenierenberg

WORCESTER, Mass., July 27, 2022 (GLOBE NEWSWIRE) -- Mustang Bio, Inc.(Mustang) (NASDAQ: MBIO), a clinical-stage biopharmaceutical company focused on translating todays medical breakthroughs in cell and gene therapies into potential cures for hematologic cancers, solid tumors and rare genetic diseases, today announced that the first patient successfully received LV-RAG1 ex vivo lentiviral gene therapy to treat recombinase-activating gene-1 (RAG1) severe combined immunodeficiency (RAG1-SCID), in an ongoing Phase 1/2 multicenter clinical trial taking place in Europe. LV-RAG1 is exclusively licensed by Mustang for the development of MB-110, a first-in-class ex vivo lentiviral gene therapy for the treatment of RAG1-SCID.

Patients with SCID have mutations in blood stem cell genes that are responsible for the development and function of infection-fighting immune cells. As a result, they are unable to mount a normal defense response against infections. The administration of LV-RAG1 includes reduced intensity conditioning prior to reinfusion of the patients own gene-modified blood stem cells.

The patient was administered LV-RAG1 without any complications. LV-RAG1 allowed the patients body to create a functioning immune system, which is responding well to the standard vaccinations for newborns, said Arjan Lankester, Principal Investigator and Professor of Pediatrics and Stem Cell Transplantation at Leiden University Medical Centre (LUMC).

Manuel Litchman, M.D., President and Chief Executive Officer of Mustang said, This first successful administration to a RAG1-SCID patient of a stem-cell based gene therapy represents a significant positive step forward for our MB-110 development program. This treatment, along with our X-linked severe combined immunodeficiency (XSCID) programs, which includes MB-107 and MB-207, has established Mustang as a leader in developing treatments for SCID patients, who are in great need of these life-saving therapies. XSCID and RAG1-SCID make up almost 60% of all SCID cases combined.1 We look forward to continuing to advance these clinical candidates, including plans to initiate a multicenter pivotal Phase 2 trial for MB-107 under Mustangs IND in the second half of this year.

LV-RAG1 has been granted Orphan Drug Designation by the European Medicines Agency. Additional clinical trial sites are expected to be added in the near future.

Signed in 2021, Mustangs exclusive, worldwide license agreement for LV-RAG1 established an ongoing partnership with LUMC and LUMCs Frank J. Staal, Ph.D., molecular immunologist and professor of Molecular Stem Cell Biology. The license agreement grants Mustang rights to certain additional lentiviral gene therapies being developed in Dr. Staals lab.

About RAG1-SCIDSevere combined immunodeficiency (SCID) due to complete RAG1 deficiency is a rare, genetic severe combined immunodeficiency disorder caused by null mutations in the RAG1 gene resulting in less than 1% of wild type V(D)J recombination activity. Patients present with neonatal onset of life-threatening, severe, recurrent infections by opportunistic fungal, viral and bacterial micro-organisms, as well as skin rashes, chronic diarrhea, failure to thrive and fever. Immunologic observations include profound T- and B-cell lymphopenia, low or absent serum immunoglobulins, and normal natural killer cell counts. As is the case with other types of SCID, RAG1-SCID is fatal in infancy unless immune reconstitution is achieved with allogeneic hematopoietic stem cell transplantation (HSCT), or autologous stem cells corrected by gene therapy.

About MB-110 (Ex Vivo Lentiviral Gene Therapy)MB-110 is a first-in-class ex vivo lentiviral gene therapy under development to treat RAG1-SCID, utilizing the LV-RAG1 vector developed in the laboratory of Frank J. Staal, Ph.D., molecular immunologist and professor of Molecular Stem Cell Biology at LUMC. Exclusively licensed to Mustang in 2021, LV-RAG1 is currently being evaluated in a Phase 1/2 multicenter, academic clinical trial (RECOMB) in Europe. Additional information on the trial can be found at http://www.clinicaltrials.gov using the identifier NCT04797260.

The same lentiviral vector drug substance produced by LUMC will be used to transduce patients cells to create the MB-110 drug product produced at Mustang Bios Worcester, MA, cell processing facility for further clinical development and to facilitate eventual commercial launch of the product.

Buffalo center fuels research that can save your life from heart disease and stroke – Buffalo News

By daniellenierenberg

Dr. Jennifer Lang splits most of her work life treating patients at Gates Vascular Institute and conducting research in her lab several floors up in the same building.

UB medical physics students Simon Wu and Emily Vanderbelt work with flow-through 3D-printed aneurysm models using X-rays in the Canon Stroke & Vascular Research Center, part of the University at BuffaloClinical and Translational Research Center on the Buffalo Niagara Medical Campus.

The arrangement suits her well as she continues promising research to learn if a stem cell-derived treatment can repair damaged heart tissue.

Lang, a cardiologist, and her University at Buffalo team, face a dilemma: The immune system revs into high gear when the heart suffers a serious setback, limiting the power of stem cells to heal.

The daunting task seems more surmountable these days because she works in a building filled with researchers of all stripes.

I do collaborations with groups that I otherwise wouldn't have. Its led to some really new, interesting results, said Lang, assistant professor in the UB Jacobs School of Medicine and Biomedical Sciences who practices with UBMD Internal Medicine and at the Buffalo VA Medical Center.

This day, a surgical team worked seamlessly to monitor her vital signs and feather a medical device through a catheter into the left side of her damaged heart. The procedure slowed her heartrate so her organs could take a couple of days to re-collect themselves and give her a fighting chance to recover.

UB-fueled research unfolds on floors five through eight of the building at 875 Ellicott St., alongside Buffalo General Medical Center.

Ten years ago, the university invested $118 million into its Clinical and Translational Research Center, and about $25 million for equipment came from industry partners who wanted to join forces with physicians, engineers and others in the science fields.

The center became the first major pieceof the UB medical school to move onto the downtown Buffalo Niagara Medical Campus, followed in late 2017 by the $375 million Jacobs School teaching and research complex, around the corner at Main and High streets.

Both foster translational medicine, which combines disciplines, resources and techniques to move benchtop research to the patient bedside, eventually strengthening community health.

Langs work symbolizes the approach.

The Buffalo native can see her high school alma mater, City Honors, from her workplace. She went to Cornell University as an undergraduate and returned to Buffalo to go to medical school. Buoyed by fellow UB students, faculty and mentors, she chose to stay in the city for her internal medicine residency and cardiology fellowship.

Lang did her classroom work and research on the UB South Campus and most of her clinical work 8 miles away, on the downtown Medical Campus.

Stairs and elevators are the only things that separate her from most of her collaborators and patients today.

I moved into this building when it opened 10 years ago, she said. At the time, I was completing my cardiology fellowship. There was a physical divide, so I was thrilled with the new arrangement. Things can happen in parallel now.

Dr. Timothy Murphy, left, director of theUB Clinical and Translational Research Center in Buffalo, works with research technician Charmaine Kirkham in their lab, which focuses on potential treatments forchronic obstructive pulmonary disease (COPD).

That was the plan, said Dr. Timothy Murphy, director of the UB Clinical and Translational Research Center.

Clinical research and health care have become more and more seamlessly integrated, he said. The building contributed to that.

Murphy, another regional native, was among those who shared and helped carry out the vision of Gates Vascular Institute founder Dr. L. Nelson Nick Hopkins III, who chaired the UB Department of Neurosurgery from 1989 to 2013 and wanted to create a more innovative vascular center.

Murphy moved his lab in 2006 from the VA Medical Center near South Campus to the UB Center for Bioinformatics and Life Sciences on the Medical Campus, so he could be involved in the design of the UB research center, on floors above Gates Vascular, as well as at the Jacobs School particularly its labs.

They always talked about physicians and researchers bumping into each other, talking to each other, and having graduate students and postdocs and technicians talk to each other, Murphy said. Having done it now for all these years, I see it really does work.

He and his research team continue a 20-year study on the bacterial infection that causes COPD in hopes it will help lead to vaccines that prevent the infection and new treatments to clear the bacteria from the lower airway.

As senior associate dean forclinical and translational researchat the Jacobs School, he is also the point person for coordinating UB-related clinical trials and encouraging collisions between health care researchers on the Medical Campus and around the world.

There were 70 such trials on the Medical Campus in 2015, when the building where he works was in its infancy. Today, there are more than 200.

"Things can happen in parallel now," says Dr. Jennifer Lang, a cardiologist, researcher and University at Buffalo assistant professor who splits her research and clinical time in the same building on the Buffalo Niagara Medical Campus.

Labs focused on obstetric and gynecological advances and keys to healthy aging occupy space near his seventh-floor lab.

The Clinical and Translational Research Center was established in 2012. UB added a biobank in 2019 to store medical specimens for ongoing clinical studies.

Its collaborative framework helped UB land a $15 million Clinical and Translational Science Awardin 2015 from the National Institutes of Health (NIH) to encourage research efforts across university departments and specialties to boost innovation, speed development of medical treatments, and reduce health disparities in poor, rural and minority communities.

The five-year grant was renewed in 2020 with nearly $22 million more, encouraging Buffalo-based researchers to work with others who got awards, including researchers with Harvard, Johns Hopkins, Stanford and Yale universities.

A printer creates a 3D model, slice by slice, at the Canon Stroke & Vascular Research Center in the University at Buffalo Clinical and Translational Research Center. Lab researchers experiment with different mixtures of six polymers to make the most malleable and useful models for medical research.

Throughout the building, the goal is to improve medical devices and treatments that make an impact in the clinics and catheter suites in the Gates Vascular Institute on the floors below the research center and provide data and education that informs others, including patients.

The eighth-floor Canon Stroke & Vascular Research Center, which tops the UB research center, is a case in point.

Ciprian Chip Ionita, its director, came to UB from Romania in 1999 and worked his first dozen years on the South Campus.

We were the first ones to move in, said Ionita, assistant professor of biomedical engineering and member of the medical school's Department of Neurosurgery.

The lab was designed to help innovate and improve medical devices and neurovascular procedures.

Part of its work involves using MRIs, CT scans and other radiological images of Gates Vascular patients to create 3D-printed models of the circulatory system and heart.

3D printing created this replica of part of a patient's spinal column at the Canon Stroke & Vascular Research Center. Researchers there push the boundaries until their findings are refined to the point where they can be applied to model-making on two highly calibrated 3D printers in the Jacobs Institute downstairs from the lab that meet FDA standards. We fail up here about 90% of the time, says Ciprian Chip Ionita, lab director. They fail maybe 1%, so were testing everything that's possible.

Medical school and other lab researchers use the models produced here to better understand how anatomy and disease of former and current patients led to poor health and, in some cases, poor surgical outcomes.

Gates Vascular surgeons also can use 3D models that replicate the anatomy of patients awaiting surgery to practice feathering catheters and medical devices through bends, nooks and crannies of the blood vessels, and deploy medical devices in spines and the circulatory system as they maneuver past muscles, bones, blockages and other obstructions that might come into play.

During practice interventions, we analyze everything, Ionita said, because we can go into these models with sensors to measure blood flow, blood pressure and more.

You can create a model that says, Here's somebody who has a carotid artery that's 50% (blocked) and he's 50 years old, Ionita said. Or we can say, 'Here is a young person in their 20s, and is fully compliant, no stenosis or whatever.' And those mechanical properties are translated by the printer.

Even cadaver donors cant do that.

The goal is to lower the rate of complications and be successful in one shot during a procedure, said Ionita, who supervises up to 10 graduate biomedical engineering students, and roughly 20 undergraduate, graduate and medical school students.

Those who pay close attention to 3D models and other medical research based on data from patients treated in the building include Dr. Elad Levy, co-director of the Gates Vascular Stroke Center; Dr. Adnan Siddiqui, director of neurological and stroke services at Kaleida Health; and Dr. Vijay Iyer, medical director of cardiology and the Structural Heart Program at Kaleida. All three have ties to UB.

Even here, Ionita said, physician-scientists and other researchers see the damage that smoking, high blood pressure and living in ZIP codes where poverty is rampant can create complications that lead to worse health and surgical outcomes.

Eric Wozniak, a senior research and development technician in the Idea to Reality lab at the Jacobs Institute, uses a microscope as he works to improve catheter technology.

Doctors and staff improve treatment protocols and surgical prowess with help from those who work on the top half of the building for UB and the Jacobs Institute. The latter is named for Dr. Lawrence D. Jacobs, a Buffalo neurosurgeon whose research led to the first treatments for multiple sclerosis.

Four years after Jacobs died in 2001, his brother Jeremy, chair of the Delaware North Cos. and the UB Council, approached the university about creating a lasting memorial for the respected physician. He later signed on to the concept of creating a multidisciplinary vascular center, starting with a $10 million donation for the institute that bears the family name.

The institute includes an atrium, caf and glass-walled spaces that overlook procedure rooms on the floor below. It has 50 employees, including more than 30 biomedical and electrical engineers, who seek company-sponsored research funding, help collect data and make prototypes for clinical trials, and work with researchers to publish their work in medical journals.

In 2016, the institute was designated a 3D Printing Center of Excellence in Health Care by Israeli-based Stratasys Ltd., a leading 3D printing-maker. In early 2018, it created a proof-of-concept Idea to Reality Center, known as i2R, to further improve medical devices and surgical techniques in the vascular space.

This is our secret sauce lab, said Siddiqui, Jacobs Institute CEO. There's nothing we do downstairs that we could not do better.

This is a device designed and built in the Idea 2 Reality lab at the Jacobs Institute in Buffalo. The lab improves medical devices and technology used in vascular procedures and treatments.

Dr. Carlos Pena, who ran the FDA Neurologic Devices Division for 15 years, joined the institute staff last year to improve the chances technology conceived and designed with help from the institute gets to market.

Every company wants to talk to him, Siddiqui said. He tells them what testing needs to be done. Some of that gets done in-house. A lot of it goes to the university or, when they have a clinical trial, that gets done downstairs so the entire ecosystem is functioning, I think better than Nick Hopkins ever imagined.

Lang, the cardiologist, doesnt miss her former workday commutes. She loves the design and location of the building that sets the standard for vascular care.

Most of her days mix benchtop research in her lab and patient visits and procedures on the floors below. When there is time, she can visit her husband, Fraser Sim, neuroscience director and associate professor at the medical school.

Because we're in such close proximity to the Jacobs School now, we're also really able to engage the medical students earlier in their careers and encourage more research, Lang said. And because we're so close to the hospital, we're able to involve medical residents and fellows in our research projects much more than ever before.

University at Buffalo medical school postdoctoral research associateToubaTarvirdizadeh focuses on cardiac research in the lab of Dr. Jennifer Lang at the UB Clinical and Translational Research Center in Buffalo.

She has spent a decade trying to find better ways for a stem cell derivative that can withstand an immune response and rejuvenate heart tissue without major complications, a result that could help patients recover from a heart attack and lessen the strain of heart failure.

Four years ago, Lang and her doctoral student researcher, Kyle Mentkowski, discovered a way that lowered the immune response in mice that received the derivative.

Mentkowski, now a post-doctorate researcher at Harvard-affiliated Massachusetts General Hospital, was talking with another group of student researchers in the building when they thought it might be a good idea to bring Dr. Jessica Reynolds, an immunologist and UB medical school associate professor, into the research.

The collaboration created robust, reproducible results in mice models, Lang said, and the start of testing in human immune cells she and her colleagues hope can benefit patients within the next decade.

Collaborators now regularly get together to chat at the Jacobs Institute.

The NIH seems very interested in this as a potential clinical therapy, Lang said, but the field as a whole is still in the beginning stages of understanding where we need to go next.

Dr. Aaron Hoffman, left, University at Buffalo medical school associate professor of surgery, and Dr. Kenneth Snyder, UB associate professor of neurosurgery, chat during a break in the Jacobs Institute atrium.

UB researchers have shared some of their findings with researchers making similar inroads elsewhere, she said, and the work spawned other collaborations with Reynolds, her research team and scientists in the UB Department of Biomedical Engineering.

This type of unplanned interaction is not a unique occurrence in this building, Lang said. Our story is just one of many.

UTSW researcher part of team awarded $36 million heart research grant – The Dallas Morning News

By daniellenierenberg

The British Heart Foundation announced the winner of its $36 million Big Beat Challenge, one of the largest non-commercial awards ever given for heart research.

The winning team, CureHeart, brings together researchers from the U.K., U.S. and Asia, including Eric Olson, professor and chair of the Department of Molecular Biology at UT Southwestern Medical Center.

Olson is the founding chair of the department and directs the Hamon Center for Regenerative Science and Medicine and the Wellstone Center for Muscular Dystrophy Research. He holds the Robert A. Welch Distinguished Chair in Science and the Annie and Willie Nelson Professorship in Stem Cell Research.

He has spent his career investigating heart and muscle development and disease, leading to his participation on the CureHeart team. The Olson Lab at UTSW has been incredibly successful in muscular research, most recently providing a new way to correct the mutation that causes Duchenne muscular dystrophy through gene editing.

CureHeart made the top of the list with its gene editing therapy aimed at curing inherited heart muscle diseases, known as cardiomyopathies.

A BHF release said the technology will seek to develop the first cures for inherited heart muscle diseases by pioneering revolutionary and ultra-precise gene therapy technologies that could edit or silence the faulty genes that cause these deadly conditions.

The project will use gene-editing technology CRISPR to complete base and prime editing in the heart for the first time.

It works by correcting or silencing a faulty gene in the pumping machinery of the heart, either by re-writing the DNA at a single location or by switching off the entire copy of the faulty gene.

The technique was described as molecules that act like tiny pencils to rewrite the single mutations that are buried within the DNA of heart cells in people with heart conditions.

It can also help the heart produce enough proteins to function normally, again by fixing or stimulating the faulty gene.

With ultra-precise base editing technology, we hope to be able to correct a single letter and larger errors in the genetic code. This would mark a breakthrough for not only genetic cardiomyopathies, but for many heart conditions, said Olson in the release.

The project is the next step toward a real-world application, having already proved successful in animals with cardiomyopathies and in human cells. Members of the team believe therapies could be delivered through an arm injection, slowing or stopping the progression of cardiomyopathies, or even curing the disease entirely.

If successful, the research could have enormous impacts.

Every year in the US, around 2,000 people under the age of 25 die of a sudden cardiac arrest, often caused by one of these inherited muscle diseases, said the release. Current treatments do not prevent the condition from progressing, and around half of all heart transplants are needed because of cardiomyopathy.

The researchers believe it could also be successful in preventing the disease from being expressed if inherited. Children who receive the faulty gene from their parents could receive the injection and never develop cardiomyopathy in the first place.

Over the last 30 years, we have made extraordinary advancements in our understanding of the genetic mistakes that cause cardiomyopathy. CureHeart is a once-in-a-generation opportunity to transform this knowledge into a cure, said Olson in the release.

The technology is still in the research and development phase, but Olson said the funds will be used to optimize the method and expand it to a larger number of genetic diseases of the heart, and could move to clinical trials in the next few years.

Differentiation of pluripotent stem cells (PSCs) is regulated through a methionine-mediated mechanism, which has now been pinpointed by Tokyo Tech researchers. They have revealed that zinc (Zn) plays a crucial role in PSC potentiation. They used these insights to design a protocol to convert PSCs into insulin-producing pancreatic cellsa high-potential diabetes therapy.

Stem cell research has gained a lot of attention in the world of medical therapeutics. Pluripotent stem cells (PSCs) can self-renew and transform into different types of cells in the body via a process called differentiation. These cells have manifold applications, such as disease modeling, drug discovery, and cell replacement therapy.

One area of focus in PSC research is diabetes treatments. A common characteristic of diabetes is having ineffective or overworked pancreatic cellscells that produce insulin. Controlling the differentiation of PSCs to produce cells is one of the major goals of research in the field. Previous studies have shown that methionine, an amino acid, plays a major role in the differentiation of PSCs. But the precise mechanism behind this has been, thus far, unknown.

To find the missing piece of this puzzle, a team of researchers from Japan, led by Prof. Shoen Kume from Tokyo Institute of Technology (Tokyo Tech), delved deeper into the methionine-mediated regulation of PSC pluripotency. In a recent study published in Cell Reports, the researchers revealed that cellular zinc (Zn) content played a crucial role in stem cell differentiation. Prof. Kume explains, Earlier research in the area has shown that if we culture PSCs in a medium which is deficient in methionine, it leads to a reduction in intracellular S-adenosyl methionine or SAM, which renders PSCs in a state of potentiated differentiation. But our study further identified that zinc (Zn) is a downstream target of methionine metabolism and it can potentiate pluripotency in undifferentiated PSCs.

In this study, the research team first cultured PSCs in a methionine-deprived environment. They found that methionine-deprivation not only reduced the intracellular protein-bound Zn levels in cells, but that it also upregulated SLC30A1, a gene that produces an important Zn transport protein.

The team then cultured hiPSCs under low Zn concentrations. They discovered that a Zn-deprived medium partially mimicked methionine deprivation and led to a decrease in cell growth and an increase in potentiated differentiation. They also found that the Zn deprived state also altered the methionine metabolism profile and eliminated undifferentiated hiPSCs. These results indicated that methionine deprivation-induced differentiation takes place by lowering the Zn content in cells.

Using the insights, the team then developed a methodology for generating insulin-producing pancreatic cells. cell transplantation is a promising treatment for diabetes, but there is a paucity of donor cells for the treatment, as well as immune-related complications that can arise from this treatment. Using PSCs to produce genetically-matching cells is a way to overcome this, explains Prof. Kume.

These findings indicate a link between Zn mobilization and methionine-induced potentiation of PSCs and provide clear a direction for future research in the field of stem cell therapies.

New TSXV listing looks to address the $3B spinal cord injury treatment market (NRX.V) – FXStreet

By daniellenierenberg

The company is developing a novel, non-invasive, bio-guided treatment to restore function of patients with acute spinal cord injuries.

Over two hundred and fifty thousand people suffer from spinal cord injuries in the US every year, with patients typically experiencing major, and mostly irreversible, loss of function that requires millions of dollars in lifetime care per patient.

NurExone is developing a revolutionary bio-guided treatment. The technology is based on exosomes, small particles that are created when stem cells proliferate, to deliver therapeutic agents to a specific location in the body. Nurexones proprietary agents, delivered by the exosomes, create an environment may support Nerves regeneration. For spine injuries, the bio-guided treatment is an agent that inhibits the PTEN protein in nerve cells, allowing nerves regeneration to occur.

The company carried out preclinical, animal studies that demonstrated that bio-guided treatment led to significant improvement, sensory recovery, and faster reflex restoration. The study reveals that Nurexones proprietary technology caused new connections in the spinal cord, repairing the damage from injuries, at least in part.

Studies also suggested that Nurexones technology may be useful for other indications including strokes and traumatic brain injuries (TBI).

The company was founded in 2020, based on research by Professor Shulamit Levenberg, Head of the Biomedical Engineering Department at Technion, and by Professor Daniel Offen, Head of the Lab for Neurosciences at the Felsenstein Medical Research Center in Tel Aviv University.

Spine related injuries are expected to increase in the future owing to motor accidents, workplace injuries, stroke, and cancer related motor disabilities. Currently, between 250,000 and 500,000 people become spinal cord injured every year worldwide, and the lifetime costs of treatments range from $1.6 million to nearly $5 million for 25-year-olds, to $1.1 million to nearly $2.7 million for 50-year-olds. The total addressable market for spinal cord trauma injuries is expected to reach $3.04 billion by 2025, with a CAGR of 3.7%.

Stepping back to look solely at exosome technology (not necessarily related to SCI), since 2018, exosomes are an emerging therapeutic field, with hundreds of millions of US dollars invested in exosome technologies by companies including Eli Lilly, Roche, and Takeda.

NurExone has obtained exclusive rights to an advanced exosome manufacturing process developed at the Technion, Israel Institute of Technology, Haifa. NurExone will be responsible for additional exosome research, management of clinical studies and commercialization of the technology for different indications not limited to Central Nerve System (CNS).

NurExones listing on the TSX.V under the symbol NRX was accomplished through an agreed reverse takeover (RTO) of EnerSpar signed on January 3, 2022. EnerSpar will acquire each ordinary share of NurExone in exchange for 17 post-consolidation EnerSpar shares, resulting in a total of 48,383,963 total shares outstanding following completion of the transaction.

Despite limited financial analyses available on the stock, it seems like a potentially unique opportunity given the fact that the market for spinal-cord treatment continues to grow, thus enabling new players in the field to partake in this ever-growing industry. Moreover, any company that delivers therapy that has the potential to unlock the secret of restoring function to patients who have experienced traumatic spinal injury, seems to be worth considering

Human iPSC co-culture model to investigate the interaction between microglia and motor neurons | Scientific Reports – Nature.com

By daniellenierenberg

Ethics statement

All human material (blood RNA, primary microglia RNA, iPSCs) used in this study was derived after signed informed consent: for blood, according to University of Oxford OHS policy document 1/03; all procedures related to the use of the primary microglia followed established institutional (McGill University, Montreal, QC, Canada) and Canadian Institutes of Health Research guidelines for the use of human cells; for iPSC, with approval from the South Central Berkshire Research Ethics Committee, U.K. (REC 10/H0505/71). The blood RNA and primary microglia RNA samples have been published previously26, as have the iPSC lines (see below).

Four healthy control iPSC lines, SFC840-03-03 (female, 67years old,35), SFC841-03-01 (male, 36,18), SFC856-03-04 (female, 78,36), OX3-06 (male, 49,37), generated from skin biopsy fibroblasts and characterized as described before, were used in this study. Additionally, the previously reported26 line AH016-3 Lenti_IP_RFP (male, 80years old), which constitutively expresses Red Fluorescent Protein (RFP) under continuous puromycin selection, was used for some live-imaging experiments.

iPSCs were cultured in mTeSR1 (StemCell Technologies) or OXE8 medium38 on Geltrex (Thermo Fisher)-coated tissue culture plates with daily medium changes. Passaging was done as clumps using EDTA in PBS (0.5mM). Cells were initially expanded at low passage to create a master stock, which was used for all experiments to ensure consistency. Cells were regularly tested negative for mycoplasma using MycoAlert Mycoplasma Detection Kit (Lonza).

iPSCs were differentiated to MNs according to our previously published protocol18,19,27. Briefly, neural induction of iPSC monolayers was performed using DMEM-F12/Neurobasal 50:50 medium supplemented with N2 (1X), B27 (1X), 2-Mercaptoethanol (1X), AntibioticAntimycotic (1X, all ThermoFisher), Ascorbic Acid (0.5M), Compound C (1M, both Merck), and Chir99021 (3M, R&D Systems). After two days in culture, Retinoic Acid (RA, 1M, Merck) and Smoothened Agonist (SAG, 500nM, R&D Systems) were additionally added to the medium. Two days later, Compound C and Chir99021 were removed from the medium. After another 5days in culture, neural precursors were dissociated using accutase (ThermoFisher), and split 1:3 onto Geltrex-coated tissue culture plates in medium supplemented with Y-27632 dihydrochloride (10M, R&D Systems). After one day, Y-27632 dihydrochloride was removed from the medium, and then the cells were cultured for another 8days with medium changes every other day. For terminal maturation, the cells were dissociated on day in vitro (DIV) 18 using accutase and plated onto coverslips or tissue culture plates coated with polyethylenimine (PEI, 0.07%, Merck) and Geltrex or tissue culture dishes coated with PDL (Sigma-Aldrich)/ Laminin (R&D Systems)/ Fibronectin (Corning). For this step, the medium was additionally supplemented with BDNF (10ng/mL), GDNF (10ng/mL), Laminin (0.5g/mL, all ThermoFisher), Y-27632 dihydrochloride (10M), and DAPT (10M, R&D Systems). Three days later, Y-27632 dihydrochloride was removed from the medium. After another three days, DAPT was removed from the medium. Full medium changes were then performed every three days.

For MNs differentiated in co-culture medium alone, all steps were performed similarly until three days after the terminal re-plating (D21). MNs were then cultured in co-culture medium as described below.

iPSCs were differentiated to macrophage/microglia precursors as described previously20,21. Briefly, embryoid body (EB) formation was induced by seeding iPSCs into Aggrewell 800 wells (STEMCELL Technologies) in OXE838 or mTeSR1 medium supplemented with Bone Morphogenetic Protein 4 (BMP4, 50ng/mL), Vascular Endothelial Growth Factor (VEGF, 50ng/mL, both Peprotech), and Stem Cell Factor (SCF, 20ng/mL, Miltenyi Biotec). After four days with daily medium changes, EBs were transferred to T175 flasks (~150 EBs each) and differentiated in X-VIVO15 (Lonza), supplemented with Interleukin-3 (IL-3, 25ng/mL, R&D Systems), Macrophage Colony-Stimulating Factor (M-CSF, 100ng/mL), GlutaMAX (1X, both ThermoFisher), and 2-Mercaptoethanol (1X). Fresh medium was added weekly. After approximately one month, precursors emerged into the supernatant and could be harvested weekly. Harvested cells were passed through a cell strainer (40M, Falcon) and either lysed directly for RNA extraction or differentiated to microglia in monoculture or co-culture as described below.

Three days after the final re-plating of differentiating MNs (DIV21), macrophage/microglia precursors were harvested as described above and resuspended in co-culture medium comprised of Advanced DMEM-F12 (ThermoFisher) supplemented with GlutaMAX (1X), N2 (1X), AntibioticAntimycotic (1X), 2-Mercaptoethanol (1X), Interleukin-34 (IL-34, 100ng/mL, Peprotech), BDNF (10ng/mL), GDNF (10ng/mL), and Laminin (0.5g/mL). MNs were quickly rinsed with PBS, and macrophage/microglia precursors re-suspended in co-culture medium were added to each well. Co-cultures were then maintained for at least 14days before assays were conducted as described below. Half medium changes were performed every 23days.

For comparisons between co-cultures and monocultures, MNs and monocultured microglia were also differentiated alone in co-culture medium.

Cells cultured on coverslips were pre-fixed with 2% paraformaldehyde in PBS for 2min and then fixed with 4% paraformaldehyde in PBS for 15min at room temperature (RT). After permeabilization and blocking with 5% donkey/goat serum and 0.2% Triton X-100 in PBS for 1h at RT, the coverslips were incubated with primary antibodies diluted in 1% donkey/goat serum and 0.1% Triton X-100 in PBS at 4C ON. The following primary antibodies were used: rabbit anti-cleaved caspase 3 (1:400, 9661S, Cell Signaling), mouse anti-ISLET1 (1:50, 40.2D6, Developmental Studies Hybridoma Bank), mouse anti-TUJ1 (1:500, 801201, BioLegend), rabbit anti-TUJ1 (1:500, 802001, BioLegend), chicken anti-TUJ1 (1:500, GTX85469, GeneTex), rabbit anti-IBA1 (1:500, 019-19741, FUJIFILM Wako Pure Chemical Corporation), goat anti-IBA1 (1:500, ab5076, abcam), rabbit anti-synaptophysin (1:200, ab14692, abcam), goat anti-ChAT (1:100, ab114P, abcam), rat anti-TREM2 (1:100, MAB17291-100, R&D Systems), rabbit anti-TMEM119 (1:100, ab185337, abcam), rat anti-CD11b (1:100, 101202, BioLegend).

After three washes with PBS-0.1% Triton X-100 for 5min each, coverslips were incubated with corresponding fluorescent secondary antibodies Alexa Fluor 488/568/647 donkey anti-mouse/rabbit/rat/goat, goat anti-chicken (all 1:1000, all ThermoFisher). Coverslips were then washed twice with PBS-0.1% Triton X-100 for 5min each and incubated with 4,6-diamidino-2-phenylindole (DAPI, 1g/mL, Sigma-Aldrich) in PBS for 10min. After an additional 5min-washing step with PBS-0.1% Triton X-100, the coverslips were mounted onto microscopy slides using ProLong Diamond Antifade Mountant (ThermoFisher). Confocal microscopy was then performed using an LSM 710 microscope (Zeiss).

For the analysis of neuronal and MN markers after differentiation, three z-stacks (2m intervals) of randomly selected visual fields (425.1425.1m) were taken for each coverslip at 20magnification. The ratios of TUJ1-positive, ChAT-positive, ISLET1-positive, ChAT-positive/ TUJ1-positive, and ISLET1-positive/ TUJ1-positive cells were then quantified using Fiji in a blinded fashion.

For the analysis of microglial markers in monoculture and co-culture, three z-stacks (1m intervals) of randomly selected visual fields (212.55212.55m) were taken for each coverslip at 40magnification. The expression of CD11b, TMEM119, and TREM2 in IBA1-positive cells in monoculture and co-culture was then quantified using Fiji.

For the analysis of apoptosis in neurons, five z-stacks images of randomly selected visual fields (212.55212.55m) were taken at 40magnification for each coverslip. The ratios of cleaved caspase 3/ TUJ1-positive cells were then quantified for neurons in monoculture and co-culture in a blinded fashion. For the analysis of apoptosis in microglia, three z-stacks images of randomly selected visual fields (212.55212.55m) were taken at 40magnification for each coverslip. The ratios of cleaved caspase 3/ IBA1-positive cells were then quantified for microglia in monoculture and co-culture.

For the analysis of microglial ramifications, five z-stacks images of randomly selected visual fields (212.55212.55m) were taken at 40magnification for each coverslip. To analyze the branching of IBA1-positive microglia in monoculture and co-culture, the average branch length, number of branch points and number of branch endpoints was determined using 3DMorph39, a Matlab-based script for the automated analysis of microglial morphology.

From the same harvest, macrophage precursors (pMacpre) were either lysed directly or differentiated to microglia in monoculture (pMGL) or microglia in co-culture with MNs (co-pMG) for 14days. pMGL were rinsed with PBS and directly lysed in the dish. For both pMacpre and pMGL, RNA was extracted using an RNAeasy Mini Plus kit (Qiagen) according to the manufacturers instructions. Co-cultures were first dissociated by 15min incubation with papain (P4762, Sigma-Aldrich) diluted in accutase (20 U/mL) and gentle trituration based on a previously published protocol40. The cell suspension was then passed through a cell strainer (70m, Falcon) to remove cell clumps. To extract co-pMG, magnetic-activated cell sorting (MACS) was then performed using CD11b-MACS beads (130093-634, Miltenyi Biotec) according to the manufacturers instructions. The panned cell population was lysed for RNA extraction using an RNAeasy Micro kit (Qiagen) according to the manufacturers instructions. In addition, RNA from human fetal microglia and blood monocytes from three different healthy genetic backgrounds wasre-used from our previous study26.

RNA from the four different healthy control lines (listed earlier) per condition (pMacpre, pMGL, co-pMG) was used for RNA sequencing analysis. Material was quantified using RiboGreen (Invitrogen) on the FLUOstar OPTIMA plate reader (BMG Labtech) and the size profile and integrity analysed on the 2200 or 4200 TapeStation (Agilent, RNA ScreenTape). RIN estimates for all samples were between 9.2 and 9.9. Input material was normalised to 100ng prior to library preparation. Polyadenylated transcript enrichment and strand specific library preparation was completed using NEBNext Ultra II mRNA kit (NEB) following manufacturers instructions. Libraries were amplified (14 cycles) on a Tetrad (Bio-Rad) using in-house unique dual indexing primers (based on41). Individual libraries were normalised using Qubit, and the size profile was analysed on the 2200 or 4200 TapeStation. Individual libraries were normalised and pooled together accordingly. The pooled library was diluted to~10nM for storage. The 10nM library was denatured and further diluted prior to loading on the sequencer. Paired end sequencing was performed using a NovaSeq6000 platform (Illumina, NovaSeq 6000 S2/S4 reagent kit, v1.5, 300 cycles), generating a raw read count of a minimum of 34M reads per sample.

Further processing of the raw data was then performed using an in-house pipeline. For comparison, the RNA sequencing data (GSE89189) fromAbud et al.28 and the dataset (GSE85839) fromMuffat et al.29 were downloaded and processed in parallel. Quality control of fastq files was performed using FastQC (https://www.bioinformatics.babraham.ac.uk/projects/fastqc/) and MultiQC42. Paired-end reads were mapped to the human GRCh38.p13 reference genome (https://www.gencodegenes.org) using HISAT2 v2.2.143. Mapping quality control was done using SAMtools44 and Picard (http://broadinstitute.github.io/picard/) metrics. The counts table was obtained using FeatureCounts v2.0.145. Normalization of counts and differential expression analysis for the comparison of pMGL and co-pMG was performed using DESeq2 v1.28.146 in RStudio 1.4.1103, including the biological gender in the model and with the BenjaminiHochberg method for multiple testing correction. Exploratory data analysis was performed following variance-stabilizing transformation of the counts table, using heat maps and hierarchical clustering with the pheatmap 1.0.12 package (https://github.com/raivokolde/pheatmap) and principal component analysis. Log2 fold change (log2 fc) shrinkage for the comparison of pMGL and co-pMG was performed using the ashr package v2.2-4747. Genes with |log2 fc|>2 and adjusted p value<0.01 were defined as differentially expressed and interpreted with annotations from the Gene Ontology database using clusterProfiler v3.16.148 to perform over-representation analyses.

Equal amounts of RNA (30ng) were reverse-transcribed to cDNA using the High-Capacity cDNA Reverse Transcription Kit (ThermoFisher) according to the manufacturers instructions. Quantitative real-time PCR was performed with Fast SYBR Green Master Mix (ThermoFisher) according to the manufacturers instructions using a LightCycler 480 PCR System (Roche). The following primers (ChAT from Eurofins Genomics, all others from ThermoFisher) were used:

Quantification of the relative fold gene expression of samples was performed using the 2Ct method with normalization to the GAPDH reference gene.

AH016-3 Lenti-IP-RFP-microglia were co-cultured with healthy control motor neurons in PEI- and Geltrex-coated glass bottom dishes for confocal microscopy (VWR). The RFP signal was used to identify microglia in co-culture. To visualize microglial movement, images of the RFP signal and brightfield were taken every~30s for 1h (22 stitched images, 20magnification) using a Cell Observer spinning disc confocal microscope (Zeiss) equipped with an incubation system (37C, 5% CO2). To image phagocytic activity, co-cultures were rinsed with Live Cell Imaging Solution (1X, ThermoFisher), and pHrodo Green Zymosan Bioparticles Conjugates (P35365, ThermoFisher) diluted in Live Cell Imaging Solution (50g/mL), which become fluorescent upon phagocytic uptake, were added. The dish was immediately transferred to the spinning disc confocal microscope, and stitched images (33, 20magnification) were acquired every 5min for 2h.

To induce pro-inflammatory (M1) or anti-inflammatory (M2) microglial phenotypes, cells were treated with Lipopolysaccharides (LPS, 100ng/mL, Sigma) and Interferon- (IFN-, 100ng/mL, ThermoFisher), or Interleukin-4 (IL-4, 40ng/mL, R&D Systems) and Interleukin-13 (IL-13, 20ng/mL, Peprotech), respectively, for 18h. Vehicle-treated (co-culture medium) cells were used as an unstimulated (M0) control.

To analyze the clustering of microglia upon pro-inflammatory and anti-inflammatory stimulation, RFP-positive microglia were imaged directly before the addition of M1/M2 inducing agents, and at 9h and 18h post-stimulation using the Cell Observer spinning disc confocal microscope (55 stitched images, 10magnification). The number of individual microglial cells and size of microglial clusters was quantified using the analyze particle function in Fiji.

After stimulation with M1/M2-inducing agents, culture supernatants were collected and spun down at 1200g for 10min at 4C. Pooled samples from three different healthy control lines for each cell type were analyzed using the Proteome Profiler Human XL Cytokine Array Kit (R&D Systems) according to the manufacturers instructions. The signal was visualized on a ChemiDoc MP imaging system (Bio-Rad) and analyzed using ImageStudioLite v5.2.5 (LI-COR). Data was then plotted as arbitrary units using the pheatmap 1.0.12 package in RStudio 1.4.1103.

In addition, to confirm the relative expression of Serpin E1 and CHI3L1 in cell culture supernatants, the Human Human Chitinase 3-like 1 Quantikine ELISA Kit (DC3L10) and Human Serpin E1/PAI-1 Quantikine ELISA Kit (DSE100, both R&D Systems) were used according to the manufacturers instructions.

pNeuron, pMGL and co-cultures were plated and maintained in WillCo-dish Glass Bottom Dishes (WillCo Wells) for 14days. Calcium transients were measured using the fluorescent probe Fluo 4-AM according to the manufacturers instructions (ThermoFisher). Cells were incubated with 20M Fluo 4-AM resuspended in 0.2% dimethyl sulfoxide for 30min at RT in Live Imaging Solution (ThermoFisher). After a washing step with Live Imaging Solution, cells were allowed to calibrate at RT for 1520min before imaging. Ca2+ images were taken by fluorescence microscopy at RT. The dye was excited at 488nm and images were taken continuously with a baseline recorded for 30s before stimulation. The stimuli used for calcium release were 50mM KCl (Sigma-Aldrich) for 30s, followed by a washing step for one minute. Microglial calcium release was stimulated by 50M ADP (Merck) under continuous perfusion for 1min, followed by a 1-min wash. Analysis of fluorescence intensity was performed using Fiji. Fluorescence measurements are expressed as a ratio (F/Fo) of the mean change in fluorescence (F) at a pixel relative to the resting fluorescence at that pixel before stimulation (Fo). The responses were analysed in 2040 cells per culture.

MNs on DIV 3345 were maintained in a bath temperature of 25C in a solution containing 167mM NaCl, 2.4mM KCl, 1mM MgCl2, 10mM glucose, 10mM HEPES, and 2mM CaCl2 adjusted to a pH of 7.4 and 300mOsm. Electrodes with tip resistances between 3 and 7M were produced from borosilicate glass (0.86mm inner diameter; 1.5mm outer diameter). The electrode was filled with intracellular solution containing 140mMK-Gluconate, 6mM NaCl, 1mM EGTA, 10mM HEPES, 4mM MgATP, 0.5mM Na3GTP, adjusted to pH 7.3 and 290mOsm. Data acquisition was performed using a Multiclamp 700B amplifier, digidata 1550A and clampEx 6 software (pCLAMP Software suite, Molecular Devices). Data was filtered at 2kHz and digitized at 10kHz. Series resistance (Rs) was continuously monitored and only recordings with stable<50 M and Rs<20% were included in the analysis. Voltage gated channel currents were measured on voltage clamp, neurons were pre-pulsed for 250ms with 140mV and subsequently a 10mV-step voltage was applied from 70 to+70mV. Induced action potentials were recorded on current clamp, neurons were held at 70mV and 8 voltage steps of 10mV, from 10 to 60mV, were applied. Data was analyzed using Clampfit 10.7 (pCLAMP Software suite).

Statistical analyses were conducted using GraphPad Prism 9 (GraphPad Software, San Diego, California USA, http://www.graphpad.com). Comparisons of two groups were performed by two-tailed unpaired t-tests and multiple group comparisons by one-way or two-way analysis of variance (ANOVA) with appropriate post-hoc tests as indicated in the figure legends. The statistical test and number of independent experiments used for each analysis are indicated in each figure legend. Data are presented as single data points and meansSEM. Differences were considered significant when P<0.05 (*P<0.05; **P<0.01; ***P<0.001; ns: not significant). GraphPad Prism 9 or RStudio 1.4.1103 were used to plot data. Final assembly and preparation of all figures was done using Adobe Illustrator 25.4.1.

Negligence in treatment of diseases like glioblastoma can be fatal, seminar told – The News International

By daniellenierenberg

Glioblastoma (GBM) is a fast-growing type of central nervous system tumour that forms from glial (supportive) tissue of the brain and spinal cord, with cells that look very different from normal ones, said Dr Ata Ul Aleem Bhatti, ex-instructor neurosurgeon, Aga Khan University Medical College, Dar as Salaam, Tanzania, and consultant neurosurgeon at the South City Hospital, Karachi.

Addressing a public awareness seminar on World GBM Day 2022 in collaboration with the Neurospinal & Cancer Care Postgraduate Institute, he said: Like most brain tumors, GBM grow more rapidly than their benign counterparts and affect the brain in many different ways depending on the part of the brain they are located.

Dr Bhatti further explained: Unfortunately, like most cancers in other parts of the body, the exact cause of GBM is unknown. Glioblastoma itself is not the only form of brain cancer, though it is the most common and most aggressive type. Other malignant brain tumours include medulloblastomas, lymphomas and anaplastic astrocytomas, to mention a few.

Various risk factors linked to developing cancer in the brain include over exposure to radiation and some rare inherited conditions. In all of these cases, the exact connection or link remains a mystery, but we do see a pattern of occurrence.

Again, unfortunately, there are no symptoms that will immediately tell someone they are developing a malignant brain tumour, however, there are some common things to look out for, when a person develops a mass or growth in the brain, either benign or malignant. These include a bad headache, but not the type one gets after spending hours in Karachi traffic or a stressful day. This headache is usually worse in the morning and persistent over several weeks. It may be associated with a feeling of wanting to vomit (nausea) or actually vomiting, which tends to make the person feel better.

Unfortunately, according to Dr Bhatti, at the moment there is no cure for brain cancers. While there are many therapies that are being tried and a lot of experimental work going on, we are yet to find a cure.

Malignant brain tumours are usually treated with a combination of surgery, radiotherapy and chemotherapy.

Sometimes, newer options like hormone therapy, immune therapy and others are also used. Which option is offered depends on the type of cancer involved. Surgery remains a main part of any treatment regime for GBM, since it allows for accurate diagnosis and also reduces the amount of tumour the body has to fight against.

In some cases, an attempt is made to remove as much of the tumour as possible to allow the radiotherapy and chemotherapy be more effective.

Dr Adeel Ahmed Memon, consultant clinical & radiation oncologist and assistant professor at the Karachi Institute of Radiotherapy & Nuclear Medicine (KIRAN), gave a radiation oncologist perspective for GBM.

Radiosurgery is a treatment method that uses specialized radiation delivery systems to focus radiation at the site of the tumor, while minimizing the radiation dose to the surrounding brain. Radiosurgery may be used in selective cases for tumor recurrence, often using additional information derived from MRS or PET scans, he said.

Studies have shown that radiation therapy provides most patients with improved outcomes and longer survival rates when given the combination of surgery, radiation and chemotherapy compared with surgery alone. Radiation also may be used as the sole treatment when a glioblastoma tumor is in an area that is not appropriate for surgery.

Guest speaker Dr Reena Kumari, consultant medical oncologist & assistant professor at Dr Ziauddin University Hospital, also shared her views regarding the role of chemotherapy, targeted & immunotherapy and discussed why GBM was difficult to treat brain tumor.

When treating GBM, she explained, what makes treatment challenging is that you have tumor cells that are not active, meaning they are dormant. These cells are known as cancer stem cells and since they are not active they do not die by radiation and chemotherapy.

Unlike other cancers such as breast or lung, brain tumors are extremely genetically heterogeneous means there is a high degree of variation within the same tumor cells that makes each individual glioblastoma molecularly distinct. This can be challenging when predicting prognosis and treatment, if it is in an area which is difficult access, or too close to major blood vessels or other important centers of the brain, it can make surgery tough, tendency of the tumor to come back aggressively is also a great challenge.

A promising targeted treatment is the anti-vascular endothelial growth factor (VEGF) monoclonal antibody bevacizumab. It has been approved by FDA for several different types of cancer, including. Angiogenesis is a key survival feature of many cancers as tumors rely on nutrients from the vasculature to proliferate

A clinical trial has found that selinexor, the first of a new class of anti-cancer drugs called selective inhibitors of nuclear export (SINE) , is able to shrink tumors in almost a third of patients with recurrent glioblastoma,

Dr Kumari urged people to be careful, saying: Negligence in treatment of diseases like GBM can be fatal. She further said that timely treatment of brain tumor was very important as chances of relapsing increases with the grade of tumor.

Dr Sadia Afsar, in-Charge, Neurosurgery Department, Abbasi Shaheed Hospital , highlighted the problems faced by patients with GBM and other brain tumors as this is ignored by community.

Government needs to realise that these conditions are quite common and provide more facilities for early diagnosis and treatment of GBM & other types of brain tumors like MRI, CT-Scan & PET-CT Scanner must be readily available across the country to enhance diagnosis.

The scarcity of Radiotherapy modalities in the country has already been highlighted by her and said that a huge time is wasted in long queue, additionally. The teaching hospitals need to also be equipped to perform proper neurosurgery department and OT, as this is the first step in any treatment programme for brain tumors, including GMBs.

What lab-grown cerebral organoids are revealing about the brain – New Scientist

By daniellenierenberg

Blobs of human brain cells cultivated in the lab, known as brain organoids or mini-brains, are transforming our understanding of neural development and disease. Now, researchers are working to make them more like the real thing

By Clare Wilson

Neil Webb

A DOZEN tiny, creamy balls are suspended in a dish of clear, pink liquid. Seen with the naked eye, they are amorphous blobs. But under a powerful microscope, and with some clever staining, their internal complexity is revealed: intricate whorls and layers of red, blue and green.

These are human brain cells, complete with branching outgrowths that have connected with one other, sparking electrical impulses. This is the stuff that thoughts are made of. And yet, these collections of cells were made in a laboratory in this case, in the lab of Madeline Lancaster at the University of Cambridge.

The structures, known as brain organoids or sometimes mini-brains, hold immense promise for helping us understand the brain. They have already produced fresh insights into how this most mysterious organ functions, how it differs in people with autism and how it goes awry in conditions such as dementia and motor neurone disease. They have even been made to grow primitive eyes.

To truly fulfill the potential of mini-brains, however, neuroscientists want to make them bigger and more complex. Some are attempting to grow them with blood vessels. Others are fusing two organoids, each mimicking a different part of the brain. Should they succeed, their lab-grown brains could model development and disease in the real thing in greater detail than ever before, paving the way to new insights and treatments.

But as researchers seek to make mini-brains genuinely worthy of the name, they move ever closer to a crucial question: at what point will their creations approach sentience?

The key to developing organoids was the discovery of stem cells,

Mesenchymal stem cell isolation and expansion

Bone marrow-derived MSCs were isolated from young (6 weeks) and old (1824 months) C57 black male mice using established techniques42,43 under a protocol approved by the Johns Hopkins University Animal Care and Use Committee. Briefly, immediately following euthanasia, whole bone marrow was flushed out from the bilateral tibias and femurs. After washing by centrifugation at 400g for 10min, cells were plated at 5 106 viable cells per ml. The culture was kept in humidified 5% CO2 incubator at 37C for 72h, when non-adherent cells were removed by changing the media.

All MSC preparations were evaluated using flow cytometry with PE or FITC-conjugated antibodies against murine Sca-1 (1:200; BioLegend 122507), CD31 (1:200; Fisher Scientific BDB554473), CD34 (1:100; eBioscience 14-0341-82), CD44 (1:100; BioLegend 103007), CD45 (1:100; BioLegend 103105), and IgG (1:100; BioLegend 400607) performed on BD LSRII (Becton Dickinson) using DIVA software. At least 10000 events were collected. FlowJo software was used to analyze and create the histograms.

Assessment for osteogenic and adipogenic differentiation was performed using established techniques43. Briefly, to induce osteogenic differentiation, old and young MSCs were seeded into 6-well plates at 1.3 104 cells/well. After 24h the media was replaced with osteogenic differentiation medium containing Iscoves medium supplemented with 100nM dexamethasone, 10mM beta-glycerophosphate, 50 M ascorbic acid, and 1% antibiotic/antimycotic. Cells were maintained in induction media with media changes every 2 days. After 14 days cells fixed in 10% formalin for 15min and calcium deposition was assessed using von Kossa staining. Calcium deposition was then quantified using a colorimetric calcium assay (Calcium CPC Liquicolour Kit StanBio, Boerne, TX) according to the manufacturers instructions. To induce adipogenic differentiation, old and young MSCs were seeded in 6-well plates at 2 105 cells/well. When confluent the media was replaced with adipogenic induction medium containing DMEM-HG, 10% FBS, 5% rabbit serum, 1uM dexamethasone, 10g/mL insulin, 200 M indomethacin, 500 M isobutylmethylxanthine (IBMX), and antibiotic/antimycotic for 3 days followed by exposure to followed by exposure to adipogenic maintenance medium (DMEM-HG, 10% FBS, insulin 10g/ml and P/S) for 3 days. After 3 cycles of induction and maintenance exposure cells were rinsed with PBS and fixed in 10% formalin for 10min. The cells were then stained with Oil Red O to assess for lipid droplets. After imaging Oil Red O extraction was performed using 100% isopropanol. Extract samples were transferred to a 96-well plate and absorbance readings were taken at 490nm to quantify extracted Oil Red O.

Confirmed MSCs were expanded in culture in media prepared by combining 490ml Medium 200 PRF (Gibco Invitrogen, Carlsbad, CA), a standard basal medium intended for culture of large vessel human endothelial cells, with 10ml Low Serum Growth Supplement (LSGS; Gibco Invitrogen). The final preparation contained 2% fetal bovine serum (FBS), 3ng/ml basic fibroblast growth factor (bFGF), 10ng/ml human epidermal growth factor, 10g/ml heparin, and 1g/ml hydrocortisone. Cells were incubated under standard conditions (5% CO2 and 37C). Expanded MSCs at low passage numbers (P2-P5) were used for the experiments. In the event frozen cells were used, they were thawed and grown for one passage prior to use in the experiments.

To prevent cell-cell interaction and assess only paracrine-mediated effects (i.e. those resulting from release of soluble factors), angiogenesis experiments were performed using bioreactor tubes (BT) constructed with CellMax semi-permeable polysulfone membrane tubing (Spectrum Labs, Rancho Dominguez, CA). These allowed the free diffusion of soluble proteins and other molecules released by the cells up to a 500kDa molecular weight cut-off, but not of the cells themselves. To load BTs, MSCs were trypsinized and suspended in Medium 200 PRF without LSGS supplementation (i.e. media devoid of stimulatory growth factors). MSCs were counted using a Scepter automated cell counter (Millipore, Billerica, MA), which had been previously standardized for accuracy. The desired number of MSCs was spun down and resuspended to a total volume of 100 ul that was injected into the BTs using a 0.5mL syringe. To compare paracrine-mediated angiogenesis by old and young MSCs, BTs were loaded with either 105 old or 105 young MSCs. Once cell injection was complete, the tubes were heat-sealed at both ends and the MSC-loaded tubes, fully submerged in media, were grown at standard culture conditions (37C, 5% CO2) for 7 days (Fig. 3a).

ELISA assays were performed to measure paracrine factor (PF) production by the MSCs contained within the BTs grown in culture. Tubes loaded with 2 105 MSCs were submerged in 5mL of alpha-MEM basal medium (Stemcell Technologies, Tukwila, WA) supplemented with 20% FBS (Gibco Invitrogen, Carlsbad, CA) in a 6-well plate. At day 7, conditioned media was collected from each well, spun down for 1min to pellet any debris, and then flash frozen at 80C. Conditioned media samples were assessed for the concentrations of vascular endothelial growth factor (VEGF), stromal derived factor-1 (SDF1) and insulin-like growth factor-1 (IGF1) by ELISA (Quantikine, R&D Systems, Minneapolis, MN) according to the manufacturers instructions.

BTs were removed at day 7 and placed in separate wells of a 6-well plate containing human umbilical vein endothelial cells (HUVECs)44. Briefly, 105 HUVECs (Gibco Invitrogen, Carlsbad, CA) suspended in Medium 200PRF were plated per well in Geltrex (Gibco Invitrogen) coated 6-well plates. Negative control wells received a bioreactor loaded with un-supplemented Medium 200PRF only (i.e. no cells). Positive control wells were plated with 105 HUVECs suspended in 1mL of Medium 200PRF supplemented with LSGS, which is known to induce HUVEC tubule formation. After 18h at standard culture conditions (37C, 5% CO2), the wells were imaged to allow quantitative analysis of the resultant HUVEC tubule network. Images were taken in the center of each well and in all four quadrants at pre-determined locations (5 pictures total), at 100x magnification. The total length of the tubule networks captured in the images of each well was measured using ImageJ software. To allow for comparisons between experiments, the total length of the tubule network in each well was normalized to the average length of the tubule network in the negative control wells, and reported as a normalized ratio.

To assess the effect of young MSC-generated PFs on PF-mediated angiogenesis by old MSCs, BTs were prepared as described above containing either 105 young or 105 old MSCs. Two BTs were placed together in a 6-well plate in 5mL MSC media and incubated for 7 days at standard culture conditions (Fig. 3b) using a BT containing old MSCs paired with either a separate BT with other old MSCs (control) or a separate BT with young MSCs. After 7 days the tubes were removed, washed with un-supplemented Medium 200 PRF, and then used separately in the HUVEC assay as described above. After the HUVEC assay was complete (18h) the BTs were placed in separate wells of 6-well plates and grown in culture for 7 additional days with collection of conditioned media for PF release.

Replicates of 105 old MSCs were cultured separately, or in co-culture with young MSCs, for 7 days using a 0.4m Transwell system in 6-well plates (Corning), which allow transfer of soluble paracrine factors released by the cells, but not of the cells themselves. Following RNA purification, library preparation, amplification, and Illumina sequencing, the open source Galaxy pipeline was used for data processing and analyses. After alignment of raw sequencing reads to the UCSC mm10 genome using HISAT2, transcript assembly, alignment quantification, count normalization, and differential expression analyses were conducted with StringTie, featureCounts, DESeq2, and Genesis. Quantitative PCR (KAPA SYBR FAST One-Step qRT-PCR, Wilmington, MA) was used to validate 24 transcripts identified by RNA sequencing. Target genes were selected based on their presence in significantly regulated pathways and quantified relative to 18S ribosomal RNA using the 2Ct method45.

To validate the results of the RNA sequencing and RT-PCR results, a functional autophagy assay was performed to assess relative autophagy between old, young, and rejuvenated old MSCs. Old, young and rejuvenated cells were cultured (or co-cultured, in the case of rejuvenated cells) for 7 days in 6-well plates (105 cells per well). On Day 8, cells were trypsinzed, counted and 104 cells were transferred to each well of a 96-well black plate with clear bottom and incubated for 6h. The Autophagy Assay Kit (Sigma Aldrich, St. Louis, MO) measures autophagy using a proprietary fluorescent autophagosome marker in a microplate reader (ex=360; em=520nm). Three separate experiments were performed in triplicate each for each condition. To account for possible differences introduced by counting cells, results for each cell type were normalized based on absorbance (450nm) of a Cell Counting Kit-8 (Dojindo Molecular Technologies, Inc. Rockville, MD).

Data are reported as mean standard error of the mean (SEM) unless otherwise indicated. Comparisons between groups for the HUVEC experiments were performed using the permutation test. For the PF ELISA data, groups were compared using the MannWhitney test. The autophagy assay and rt-PCR results were assessed using two-tailed t tests. For these experiments a p-value < 0.05 was deemed significant. In the RNA sequencing differential expression analysis, a false discovery rate (FDR) of <0.05 was considered significant.

Stem cells: Could we gain the power to induce cell regeneration? Dr Catherine Berry – The Scotsman

By daniellenierenberg

In short, stem cells initiate the production of new tissue cells, which can then replace their diseased counterparts.

Mesenchymal stem cells (MSCs) are adult stem cells found in many areas of the body such as bone marrow. The unique thing about these cells is their compatibility with a range of tissues such as bone, cartilage, muscle, or fat. MSCs respond to injury or disease by migrating to these damaged areas, where they restore tissue function by replacing the damaged cells.

Sign up to our Opinion newsletter

It has recently been shown that the success of MSCs relies on their ability to release cell signals their mechanism to initiate tissue regeneration. These signals are packaged into extracellular vehicles (EVs) which are essentially bubbles of information. These are released by MSCs and taken up by the injured or diseased tissue cells to kickstart their inbuilt process of regeneration.

Through funding from the Royal Society of Edinburgh, research has started into the development of artificial EVs as a viable alternative to cell therapy. These EVs will contain the key molecules released by stem cells when they are responding to injury cues in the body.

The power to induce tissue regeneration would provide a significant new tool in biomedical treatment, such as incorporating EVs into synthetic hydrogels within a wound dressing to encourage and accelerate healing.

Within the lab setting, we have been able to manipulate stem cell cultures to produce EVs with different signal make-ups, and accurately identify their properties.

Controlling and identifying the different make-ups contained in EV signals which in turn induce different cell responses is crucial if we want to operationalise their use in medicine.

We now aim to synthesise artificial vesicles, or bubbles, for different clinical problems, such as, for example, bubbles with potent wound-healing properties that would help our ability to use new artificial stem cell therapy.

The research is underway and it is showing promise that we may be able to harness the regenerative power of stem cells in the near future.

An artificial EV-based approach also has several advantages over stem cell-based therapies, such as having increased potency and greater consistency in treatment, and at a lower cost to carry out.

Both inside and on the surface of the body, we would have the ability to induce a process vital to medical treatment we work with every day and, in turn, open a whole new avenue of possibilities in biomedical science.

S’porean doctor, a sought-after top expert in cell therapy, appointed to WHO expert panel – The Straits Times

By daniellenierenberg

SINGAPORE - A Singaporean doctorwho is one of the top cell therapy experts in the worldhas been appointed to a World Health Organisation (WHO) expert panel.

Dr Mickey Koh is so sought-after in his field that for the past 15 years, he has been holding two jobs in two different countries.

The 56-year-old shuttles between England and Singapore, spending six weeks at a time in London, where he oversees the haematology department and looks after bone marrow transplant patients at St George's University Hospital, before returning to Singapore for a week and a half to head the cell therapy programme at the Health Sciences Authority.

Cell therapy is a growing field of medicine that uses living cells as treatment for a variety of diseases and conditions. This is an increasingly important therapeutic area and both his employers have agreed to his unusual schedule.

Over in London, Dr Koh is head of the Haematology Department at St George's Hospital and Medical School. In Singapore, he is the programme and medical director of the cell and gene therapy facility at the Health Sciences Authority.

In May, Dr Koh was selected to be on the WHO Expert Advisory Panel on Biological Standardisation.

Individuals on the panel have to be invited by WHO to apply, and are well recognised in their respective scientific fields. Eminent names on the panel include the current president of the Paul-Ehrlich-Institut in Germany, which is the country's federal agency, medical regulatory body and research institution for vaccines and biomedicine.

The WHO panel, which is made up of about 25 members, provides detailed recommendations and guidelines for the manufacturing, licensing and standardisation of biological products, which include blood, monoclonal antibodies, vaccines and, increasingly, cell-based therapeutics.

The recommendations and advice are passed on to the executive board of the World Health Assembly, which is the decision-making body of WHO.

Dr Koh's role had to be endorsed by the British government and was a direct appointment by the director-general of WHO.

His appointment as a panel expert will last for a term of four years.

Speaking to The Straits Times, Dr Koh shared his thoughts about the importance of regulation: "We are well aware that there is a very lucrative worldwide market peddling unproven stem cell treatments, where side effects are often unknown, and such unregulated practice can result in serious harm.

"This is already happening. People are claiming that you can use stem cells to treat things like ageing, and even very serious conditions like strokes, without any evidence."
