A team of biomedical engineering researchers, led by the University of Minnesota, has created a revolutionary 3D-bioprinted patch that can help heal scarred heart tissue after a heart attack. The discovery is a major step forward in treating patients with tissue damage after a heart attack.

According to the American Heart Association, heart disease is the No. 1 cause of death in the U.S. killing more than 360,000 people a year. During a heart attack, a person loses blood flow to the heart muscle and that causes cells to die. Our bodies cant replace those heart muscle cells so the body forms scar tissue in that area of the heart, which puts the person at risk for compromised heart function and future heart failure.

In this study, researchers from the University of Minnesota-Twin Cities, University of Wisconsin-Madison, and University of Alabama-Birmingham used laser-based 3D-bioprinting techniques to incorporate stem cells derived from adult human heart cells on a matrix that began to grow and beat synchronously in a dish in the lab.

Watch a video of the cells beating on the patch.

When the cell patch was placed on a mouse following a simulated heart attack, the researchers saw significant increase in functional capacity after just four weeks. Since the patch was made from cells and structural proteins native to the heart, it became part of the heart and absorbed into the body, requiring no further surgeries.

This is a significant step forward in treating the No. 1 cause of death in the U.S., said Brenda Ogle, an associate professor of biomedical engineering at the University of Minnesota. We feel that we could scale this up to repair hearts of larger animals and possibly even humans within the next several years.

Ogle said that this research is different from previous research in that the patch is modeled after a digital, three-dimensional scan of the structural proteins of native heart tissue. The digital model is made into a physical structure by 3D printing with proteins native to the heart and further integrating cardiac cell types derived from stem cells. Only with 3D printing of this type can we achieve one micron resolution needed to mimic structures of native heart tissue.

We were quite surprised by how well it worked given the complexity of the heart, Ogle said. We were encouraged to see that the cells had aligned in the scaffold and showed a continuous wave of electrical signal that moved across the patch.

Ogle said they are already beginning the next step to develop a larger patch that they would test on a pig heart, which is similar in size to a human heart.

The research was funded by the National Science Foundation, National Institutes of Health, University of Minnesota Lillehei Heart Institute, and University of Minnesota Institute for Engineering in Medicine.

Scientists at the University of California San Francisco have discovered a new function of lungs: They make blood which leads to a new wellspring of stem cells as well.

The astonishing breakthrough comes courtesy of refinement to microscopic video imaging that allows researchers to probe individual cells within blood vessels of a living host's lungs in this case, mice lungs.

The findings have far-reaching implications for human study: Researchers were surprised to find that not only did the lungs produce more blood cells, they did so in volumes that indicated more than half of all platelets in circulation critical for clotting are produced by the lungs.

The significance for the blood stem cells also was compelling. The newly discovered pool of stem cells is capable of restoring blood production when bone marrow stem cells are depleted. This could lead to novel approaches to treating leukemia, a cancer of white blood cells that crowds out red blood cells, and bone cancer, which destroys the body's ability to manufacture red blood cells.

This finding definitely suggests a more sophisticated view of the lungs that theyre not just for respiration but also a key partner in formation of crucial aspects of the blood, said pulmonologist Mark R. Looney, a professor of medicine and of laboratory medicine at the University of California, and the research's senior author. What weve observed here in mice strongly suggests the lung may play a key role in blood formation in humans as well. The report was published online at Nature.com.

The new imaging approach allowed scientists to examine interactions between the immune system and platelets in the lungs. While following the interactions, they discovered a surprisingly large population of cells that produce platelets called megakaryocytes. Though these cells were observed in the lungs previously it was generally though that they exist primarily in bone marrow.

Researchers were baffled and more detailed imaging followed. Once they zeroed in on these cells, they soon realized that they not only took up residence in the lungs, they also were producing 10 million platelets per hour there evidence that more than half of platelet production actually occurs in the lungs (in the mice models).

To be able to track blood stem cells and blood production, researchers transplanted donor lungs to mice with fluorescent-dye-tinted megakaryocytes. They followed the fluorescent cells as they traveled to the new lungs.

In another experiment, scientists wanted to determine if lungs that already had these platelet producers imbedded would spur platelet production in mice with low platelet counts, so they transplanted lungs with fluorescent-tinted megakaryocytes into mice predetermined to have low platelet counts. The transplanted lungs quickly sprung into action and restored normal platelet levels.

In yet another experiment, researchers transplanted healthy lungs with all cells fluorescently tinted into mice without bone marrow blood stem cells. The fluorescent marker cells quickly traveled to the damaged bone marrow and began production of myriad cells including T cells, which are key immune cells.

The exact mechanism behind the bone marrow-lung blood production is not yet known. Its possible that the lung is an ideal bioreactor for platelet production because of the mechanical force of the blood, or perhaps because of some molecular signaling we dont yet know about, said Guadalupe Ortiz-Muoz, a postdoctoral researcher and the researchs co-author. But more research is sure to follow.

Now medical scientists and researchers can zero in on proving in human models that blood components stem cells key among them travel more freely than previously though, which could lead ultimately to advances in treatment options for various blood disorders.

SAN CLEMENTE, Calif., April 20, 2017 (GLOBE NEWSWIRE) -- David Steenblock, an osteopathic physician based in San Clemente, CA, uses stem cells and other therapies to achieve significant and improved lifestyle outcomes for many stroke patients.

Many of our cases have demonstrated improved mobility for stroke victims who received stem cell therapy, along with other therapies, including chelation and hyperbaric oxygen, says Dr. Steenblock.

One patient who suffered a stroke several years ago, came to Dr. Steenblocks clinic to undergo the full stroke program. This included EDTA chelation, a procedure that removes heavy metals from the blood, and hyperbaric oxygen therapy, along with stem cells from his bone marrow to effect healing and restoration.

After having the bone marrow stem cells, the patients eyesight improved, and both of his knees, which hadnt been working well, were back to functioning almost normally. In addition, his hip joint went back to normal function and he believes his balance when walking has improved tremendously.

The EDTA Chelation Therapy, a treatment used to remove heavy metals from the blood, was used with hyperbaric oxygen, which can lead to significant neurologic improvements for stroke patients.

Dr. David Steenblock is a leading-edge physician in many fields of medicine, from stroke care, to acute brain trauma, to generative and cell-based medicine in the treatment of ALS, Cerebral Palsy and other chronic and degenerative diseases.

The New Cellogica Website Features In-Depth Information about the Skin Care Product, which Includes Stem Cell Technology

LOS ANGELES, CA / ACCESSWIRE / April 20, 2017 / The founders of Cellogica, a top line of skincare products that utilize stem cells and other innovative ingredients, are pleased to announce the re-launch of their website, Cellogica.com.

To check out the recently revised website, which is now easier than ever to navigate and features updated information about Cellogica, please visit http://www.cellogica.com at any time.

As a company spokesperson noted, Cellogica's "Two Secrets of Youth" involve the use of stem cell technology and also its MAC-5 Complex, which includes five ingredients that may help the skin look as young as possible. Rather than merely repairing the skin, Cellogica may actually help stop the loss of existing skin stem cells, as well as prevent premature aging.

Cellogica features a day cream, a non-greasy and light product which is designed to protect and enhance the skin and provide it with a natural barrier to the damaging UV rays of the sun and harsh weather. It also includes a night cream that works as the user sleeps by naturally repairing, restoring and regenerating the skin.

As the spokesperson noted, because skin stem cells are responsible for regenerating new and healthy skin cells, the founders of Cellogica were inspired to create a skin care cream that contains stem cells.

"Our revolutionary Stem Cell Technology is derived from strains of rare Swiss apples (Malus Domestica) and the Alpine Rose (Rhododentron Ferrugineum)," the spokesperson said, adding that together, these two very powerful stem cell extracts may allow for the regeneration of new skin stem cells, prevent the loss of existing skin stem cells, and increase the skin's barrier function.

"They may protect and repair the skin and combat against chronological aging, thus leading to fresh, healthy and vibrant looking skin."

The MAC-5 Complex is the other key component to Cellogica's ability to help improve the appearance of the skin. The proprietary combination includes Syn-Coll, which is an aqueous unpreserved glycerin-based solution that was developed to reduce wrinkles, as well as stimulate collagen synthesis. The other four ingredients in the MAC-5 Complex are RonaFlair LDP, hyaluronic acid, Syn-Ake, and Kojic acid, which may help eliminate blotchy skin while evening out the skin tone.

About Cellogica:

Cellogica is a premiere skincare line utilizing newly discovered stem cells to stop and reverse the physical signs of aging. To learn more about the product, please visit their website, http://www.cellogica.com.

Skin 2 Skin Care Anti-Sagging Renewal Serum is a highly-concentrated lifting serum created to restore a tighter, more youthful appearance. On application, the silky serum immediately improves the texture and feel of the skin while complex peptides and stem cells work over time to diminish the appearance of sagging and wrinkles. It provides essential nourishment that helps skin act and appear younger. After a month of use, Marta, the founder of Truth In Aging, reported firmer and more lifted skin, especially around the cheeks and jawline.

Anti-Sagging Renewal Serum features two advanced peptide complexes. Syn-Coll (Palmitoyl Tripeptide-5) has been shown to help reduce the appearance of any lip and nasal labial lines while improving facial definition. Syn-Tacks (Palmitoyl Dipeptide-5 and Palmitoyl Dipeptide-6 Diaminohydroxybutyate) supports the epidermis and stimulates collagen, laminin and elastin. In addition, green tea stem cell extract is used for its powerful ability to renew the skin. This formula is free of parabens, petroleum, mineral oil, paraffin, phthalates, sulfates, PABA, synthetic color and fragrance. Apply it to the face and neck for stronger, sag-resistant skin.

Tested for 30 days and recommended by Marta:

When I chatted to Skin 2 Skin founder Ken Simpson about Anti-Sagging Renewal Serum ($73), he went out of his way to point out that it contains dimethicone, adding that while he appreciates that some in the Truth In Aging community wont like this, the ingredient does wonders for scars. It didnt put me off when testing this serum, and I am most impressed with the results.

This serum can certainly be added to our arsenal of firming creams. I found that my skin looked a little lifted, especially around the jawline and lower cheeks. Overall, my skin is firmer and softer. As a bonus, as promised by Ken, I found that an odd little callused scar which appeared one day about a year ago on the site of a blemish, is much reduced. Nothing had helped in the past. Good job, Skin 2 Skin.

One of the things I like about this creamy-textured serum, is that the ingredients list doesnt take an everything-but-the-kitchen-sink approach. It is tightly focused on two very good peptide complexes, green tea stem cells and the aforementioned silicone.

Syn-tacks is a combination of two synthetic peptides. According to the manufacturer, they interact with the most relevant protein structures of the dermal-epidermal junction and stimulates a broad spectrum of things responsible for youthful skin laminin V, collagen types IV, VII and XVII and integrin all at once. For example, collagen IV activity is increased by a whopping 190 percent, according to the manufacturer.

Syn-Coll is a peptide molecule that works in two ways. First, it boosts collagen by mimicking the bodys own mechanism to activate transforming growth factor beta, TGF- (Tissue Growth Factor), a key element in the synthesis of collagen. It also protects collagen from degradation through the inhibition of matrix metalloproteinases (MMP).

My objection to silicone in skincare is that it has been a stalwart of department store beauty brands for decades, used to impart a superficial silkiness to the skin and inexpensively bulk up the formula. However, Skin 2 Skin has consciously introduced it here to help soften and reduce scars and blemishes. As I mentioned earlier in this review, I can attest to this working. Independent research has demonstrated that

silicone increases hydration of stratum corneum, helping to regulate fibroblast production and reduction in collagen production. The result is a softer and flatter scar.

As always with Skin 2 Skin, this is a highly effective formula that does what it sets out to do and contains no nasties. For those looking to achieve firmer, more velvety skin, this is definitely on the must try list.

Based on human stem cells derived from skin samples, researchers from the University of Luxembourg succeeded in obtaining tiny three-dimensional cultures of cerebral tissue whose behavior is similar to the human midbrain. Credit: scienceRELATIONS / University of Luxembourg

The most complex organ in humans is the brain. Due to its complexity and, of course, for ethical reasons, it is extremely difficult to do scientific experiments on it ones that could help us to understand neurodegenerative diseases like Parkinsons, for example. Scientists at the Luxembourg Centre for Systems Biomedicine (LCSB) of the University of Luxembourg have now succeeded in turning human stem cells derived from skin samples into tiny, three-dimensional, brain-like cultures that behave very similarly to cells in the human midbrain.

In the researchers petri dishes, different cell types develop, connect into a network, exchange signals and produce metabolic products typical of the active brain. Our cell cultures open new doors to brain research, says Prof. Dr. Jens Schwamborn, in whose LCSB research group Developmental and Cellular Biology the research work was done. We can now use them to study the causes of Parkinsons disease and how it could possibly be effectively treated. The team publishes its results in the prestigious scientific journal Stem Cell Reports.

The human midbrain is of particular interest to Parkinsons researchers: it is the seat of the tissue structure known medically as thesubstantia nigra. Here, nerve cells specifically dopaminergic neurons produce the messenger dopamine. Dopamine is needed to maintain smooth body movements. If the dopaminergic neurons die off, then the person affected develops tremors and muscle rigidity, the distinctive symptoms of Parkinsons disease. For ethical reasons, researchers cannot take cells from thesubstantia nigrato study them. Research groups around the world are therefore working on cultivating three-dimensional structures of the midbrain in petri dishes. The LCSB team led by stem cell researcher Jens Schwamborn is one such group.

Brain-like tissue for research

The LCSB scientists worked with so-called induced pluripotent stem cells stem cells that cannot produce a complete organism, but which can be transformed into all cell types of the human body. The procedures required for converting the stem cells into brain cells were developed by Anna Monzel as part of her doctoral thesis, which she is doing in Schwamborns group. I had to develop a special, precisely defined cocktail of growth factors and a certain treatment method for the stem cells, so that they would differentiate in the desired direction, Monzel describes her approach. To do this, she was able to draw on extensive preparatory work that had been done in Schwamborns team the years before. The pluripotent stem cells in the petri dishes multiplied and spread out into a three-dimensional supporting structure producing tissue-like cell cultures.

Our subsequent examination of these artificial tissue samples revealed that various cell types characteristic of the midbrain had developed, says Jens Schwamborn. The cells can transmit and process signals. We were even able to detect dopaminergic cells just like in the midbrain. This fact makes the LCSB scientists results of extraordinary interest to Parkinsons researchers worldwide, as Schwamborn stresses: On our new cell cultures, we can study the mechanisms that lead to Parkinsons much better than was ever the case before. We can test what effects environmental impacts such as pollutants have on the onset of the disease, whether there are new active agents that could possibly relieve the symptoms of Parkinsons or whether the disease could even be cured from its very cause. We will be performing such investigations next.

Samples of human origin

The development of the brain-like tissue cultures not only opens doors to new research approaches. It can also help to reduce the amount of animal testing in brain research. The cell cultures in the petri dishes are of human origin, and in some aspects resemble human brains more than the brains of lab animals such as rats or mice do. Therefore, the structures of human brains and its modes of function can be modelled in different ways than it is possible in animals. There are also attractive economic opportunities in our approach, Jens Schwamborn explains: The production of tissue cultures is highly elaborate. In the scope of our spin-off Braingineering Technologies Sarl, we will be developing technologies by which we can provide the cultures for a fee to other labs or the pharmaceutical industry for their research.

Plasticell, a developer of cell therapies including hematopoietic cell replacement therapies, recently announced it has partnered with Kings College London to progress preclinical trials of its artificial blood platelet product, manufactured from pluripotent stem cells. The work is supported by a MedCity research grant which funds collaboration between leading SMEs and academics from London universities.

Over 10 million units of platelets are transfused worldwide each year in one of the most common procedures in clinical medicine. However, platelets derived from human donors can transmit infections and trigger serious immune reactions that eventually render the therapy ineffective (a condition known as alloimmune refractoriness). In addition, since platelet donations require pathogen testing and cannot be frozen for later use, supply shortages can occur under certain circumstances.

Plasticell has developed robust, cost-effective methods of producing functional platelets from human induced pluripotent stem cells (iPSCs) and has scaled these up to intermediate bioreactor level, allowing manufacture of product for pre-clinical studies. Kings College will contribute world-leading expertise and in vivo models to characterise the dynamics, lifespan, safety and efficacy of transfused platelets.

In addition to providing a more stable and safe supply of universal platelets, the use of iPS cells would allow us to create immunologically compatible matched platelets for patients suffering from alloimmune refractoriness, commented Dr Marina Tarunina, Principal Scientist leading the project at Plasticell.

The project is part of Plasticells hematopoietic cell therapy portfolio, which includes the expansion of umbilical cord- and bone- derived hematopoietic stem cells, and the manufacture of various blood cell types. Plasticell recently announced it had received Innovate UK funding for a 1.1M project to manufacture red blood cells from pluripotent stem cells, in collaboration with the University of Edinburgh.

About Plasticell Plasticell is a biotechnology company leading the use of high throughput technologies to develop stem cell therapies. The Companys therapeutic focus is in hematopoietic stem cell therapy, anaemia and thrombocytopenia, cancer immunotherapy and diabetes/obesity. Plasticells Combinatorial Cell Culture (CombiCult) platform technology, allows it to test very large numbers of cell culture variables in combinations to discover optimal laboratory protocols for the manipulation of stem cells and other cell cultures and has received a number of industry awards including the Queens Award for Enterprise in Innovation and the R&D 100 Award.

The Husaini Haematology and Oncology Trust will soon provide facilities of bone marrow transplant and stem cell therapies at its newly established Blood Transfusion Centre and Thalassaemia Centre that was inaugurated by the city director health on Tuesday.

Speaking at the inaugural ceremony, Karachi director health Dr Muhammad Toufique urged the trust officials to share the data of patients undergoing blood transfusions, stem cell therapies and bone marrow transplant.

He said the data would help the Sindh government formulate a plan to establish more such facilities in the future. In addition to the blood screening and storage facilities, the centre is providing blood transfusion service to children suffering from genetic blood disorders as well as diagnostic services related to blood disorders.

This is a state-of-the-art blood transfusion and thalassaemia centre where bone marrow transplant and stem cell therapies would be started very soon, said a renowned haematologist associated with the Husaini Blood Bank, Dr Sarfraz Jaffery, at the inaugural ceremony of the blood transfusion and thalassaemia centre located at Qalandaria Chowk, North Nazimabad.

The head office of the Husaini Haematology and Oncology Trust is equipped with a diagnostic lab, blood bank having storage capacity of around 3,000 blood bags and blood transfusion centre for thalassaemic patients while its management is also planning to introduce bone marrow transplant and stem cell therapy services at the same facility in the near future.

Felicitating the trust officials, the city director health vowed to support them in their services. He said the government was also striving hard for provision of safe blood to thalassaemic children and other patients.

Dr Toufique hoped that institutions like Hussaini would come forward to support the government in establishing such centres in the province. Talking to journalists, the director health said steps were being taken to control the outbreak of Chikungunya in the city.

He said the health department was in contact with the municipal authorities to start fumigation in various areas of Karachi to eliminate the mosquitoes and prevent people from mosquito-borne diseases, including dengue and Malaria.

The Sindh government was planning to merge the Malaria and Dengue Prevention and Control Cells under one project director, who would be utilizing all the resources to eliminate the mosquitoes that were responsible for the deadly infectious diseases in the province, he added.

I would also urge people to take precautionary measures, prevent themselves and their children from mosquitoes by using repellents, improving sanitation conditions in their residential areas and adopt other preventive measures to protect themselves against the mosquitoes, he advised.

Earlier, speaking at a workshop on thalassaemia management held at the same place, noted haematologists of the country stressed the need for promoting the culture of prevention from diseases in the country.

They called for the implementation of laws regarding thalassaemia screening, saying that both the government and private sector could not treat the increasing number of thalassaemic patients.

Senior haematologist from Lahore, Prof Dr Jovaria Mannan, urged the doctors and researchers to use latest research methods in the field of haematology.

Husaini trust plans to perform bone marrow transplants, stem cell therapy - The News International

A team of researchers in Japan has combined simple agarose with advanced machine learning techniques to study the differentiation of stem cells.

Asian Scientist Newsroom | April 20, 2017 | In the Lab

AsianScientist (Apr. 20, 2017) - Stem cell differentiation can now be seen thanks to a combination of machine learning and microfabrication techniques developed by scientists at the RIKEN Quantitative Biology Center in Japan. The results, published in PLOS ONE, followed the differentiation of human mesenchymal stem cells (MSC) which are easily obtained from adult bone marrow.

MSCs have proven to be important for regenerative medicine and stem cell therapy because they can potentially repair many different types of organ damage. Depending on the way the cells are grown, the results can be quite different, making controlling differentiation is an important goal.

Observing MSC differentiation under different conditions is an essential step in understanding how to control the process. However, this has proved challenging on two fronts. First, the physical space in which the cells are grown has a dramatic impact on the results, causing significant variation in the types of cells into which they differentiate. Studying this effect requires consistent and long lasting spatial confinement. Second, classifying the cell types which have developed through manual observation is time consuming.

Previous studies have confined cell growth with fibronectin on a glass slide. The cells can only adhere and differentiate where the fibronectin is present and are thus chemically confined. However, this procedure requires high technical skill to maintain the confinement for an extended period of time. To overcome this, the first author of the study, Dr. Nobuyuki Tanaka, decided to look for a new way to confine them. Using a simple agarose gel physical confinement system, he found that he could maintain them for up to 15 days.

It was wonderful to be able to do this, because agarose gel is a commonly used material in biology laboratories and can be easily formed into a micro-cast in a PDMS silicone mold, Tanaka said.

The advantage of this system is that once the PDMS molds are obtained the user only needs agarose gel and a vacuum desiccator to create highly reproducible micro-casts.

Tanaka's paper also describes an automated cell type classification system, using machine learning, which reduces the time and labor needed to analyze cells.

Combined together, these tools give us a powerful way to understand how stem cells differentiate in given conditions, he added.

SINGAPORE - It was a bone marrow match that defied the odds of one in 20,000 - not once, but twice.

Just months after his first match fell through when the patient withdrew from treatment, Mr Phil Tan, 27, was again identified as a suitable bone marrow donor for another patient.

His donation saved the life of eight-year-old Ryssa, who was diagnosed with a rare blood disease called Myelodysplastic Syndrome about three years ago. Both met for the first time on Wednesday (April 19). Ryssa received the transplant just before her seventh birthday.

Mr Tan was one of 22 Singaporeans who were honoured by Minister for Home Affairs and Law K. Shanmugam for saving the life of a patient through the donation of their bone marrow.

"We celebrate those who have come forward without expecting a benefit, other than making a huge difference in someone else's life. It is the real spirit of giving," said Mr Shanmugam, who is a patron of the Bone Marrow Donor Programme (BMDP).

Bone marrow or blood stem cell transplant is the best treatment option for patients diagnosed with blood diseases such as leukaemia and lymphoma.

At any one time, there are at least 50 patients waiting to find a matching donor.

Siblings of the patient are the first options for a donation, as they have a one in four chance of DNA compatibility for a transplant.

When that fails, the next option would be a match with a volunteer donor registered in the BMDP.

To date, more than 75,000 volunteers have joined the BMDP register, which records the genetic type of each person.

Since 2015, more than 50 Singaporeans have donated their bone marrow to patients in Singapore and overseas, including in the United States, Britain, Canada and France.

The BMDP, which was set up in 1993, aims to increase the size of the local donor register by another 50,000 by next year.

Cardiovascular disease is one of the leading causes of death in the world with approximately 30% of global mortality attributed to it.Cardiovascular disease conditions lead to damage of cardiac muscle cells resulting in defective heart function.

Stem cell therapy, though a relatively young science, is one of the upcoming treatment options for such diseases in the near future. In principle, stem cells from embryos can be made to differentiate into many functional cell types including heart cells, which can be effectively used to replace damaged cells in heart patients. To achieve this, scientists are constantly trying to understand the developmental process by which the heart is formed from various progenitors in a growing embryo. Once we understand this pathway at an organismal level, efforts can be made to use these stem cells for regenerative medicine.

A team of scientists led by Bruno Reversade from Singapore and Ian Scott from the University of Toronto have come together to study heart development in the Zebrafish model.

Zebrafish, scientifically called Danio rerio, is one of the powerful models for studying various organ functions. Although there are major structural differences between zebrafish and humans, there are strong similarities at the genetic and morphological levels. One of the biggest advantages of using zebrafish is that unlike mice, rats or monkeys, zebrafish embryos are transparent and hence provide a tractable system for visualizing these important developmental processes in situ.

During embryonic development, early heart development requires the activation of one of the important signaling pathways called Nodal or TGF pathway. Depending on the activation levels of Nodal, different cells become different stem cell types. Hence, there has to be a mechanism for fine-tuning of this signaling to produce these activity thresholds. Scientists from these two groups have recently identified the candidates involved in this fine-tuning.

Researchers recently identified a mutation, which leads to zebrafish with no heart at all. This suggests that this mutation somehow alters an early developmental process in heart formation. Interestingly, this gene encodes for a protein called Apelin receptor. So how does the Apelin receptor affect heart development? Scientists revealed that mutation in this receptor caused lower levels of Nodal signaling in mutant embryos as compared to the normal ones, thus failing to induce the formation of cardiac stem cells. When Nodal activity is artificially elevated in embryos that lack the Apelin receptor, they were able to develop hearts further confirming the role of Apelin receptor in this pathway.

A detailed understanding of this molecular cross-talk could help in the derivation of specific cell types from human embryonic stem cells for regenerative medicine, says Bruno Reversade, a human geneticist at the A*STAR Institute of Medical Biology, who co-led the investigation.

Further, this collaborative study showed that the Apelin receptor does not work in cells that produce or receive Nodal signals, suggesting that the Apelin receptor modulates Nodal signaling levels by acting in cells that lie between the cells that release Nodal signals and the cardiac progenitors.

In brief, this receptor functions as a distant regulator for fine-tuning the expression of the Nodal pathway during early stages of heart development ensuring proper cardiac development. One important area of future study is to determine whether modulating the levels of this receptor can prove useful for patients with various heart disorders.

One of the problems with heart attacks (as if there weren't enough already) is that when the heart heals afterwards, it grows scar tissue over the part of the heart that was damaged. That scar tissue never does become beating heart tissue, so it leaves the heart compromised for the rest of the patient's life. There may be hope, however, as scientists from the University of Minnesota have created a new patch that allows the heart to heal more completely.

First of all, yes, this has been done before. We have already seen experimental "heart patches" from places like the University of Tel Aviv, Brown University and MIT, which allow the heart to heal with a minimum of scar tissue growth.

One of the things that makes this latest patch unique is the fact that it's 3D-bioprinted out of structural proteins native to the heart. It takes the form of a scaffolding-like matrix, which is subsequently seeded with cardiac cells derived from stem cells. The result is a patch of material, similar in structure and material to heart tissue, containing actual functioning heart cells as opposed to inert scar tissue.

In lab tests, one of the patches was placed on the heart of a mouse that had suffered a simulated heart attack. Within just four weeks, the scientists noted a "significant increase in functional capacity." The patch was ultimately absorbed by the body, so no additional surgeries were required to remove it after its job was done.

"We were quite surprised by how well it worked given the complexity of the heart," says associate professor Brenda Ogle, who is leading the research. "We were encouraged to see that the cells had aligned in the scaffold and showed a continuous wave of electrical signal that moved across the patch."

A larger patch is now in the works, which will be tested on a pig heart.

Other institutions involved in the study include the University of Wisconsin-Madison and University of Alabama-Birmingham. A paper on the research was recently published in the journal Circulation Research.

Heart-healing patch has got the beat - New Atlas

April 18, 2017 by Gian Galassi

A research team at University of Wisconsin School of Medicine and Public Health has treated its first patient in an innovative clinical trial using stem cells for the treatment of heart failure that develops after a heart attack.

The trial is taking place at University Hospital, one of three sites nationwide currently enrolling participants. The investigational CardiAMP therapy is designed to deliver a high dose of a patient's own bone-marrow cells directly to the point of cardiac injury to potentially stimulate the body's natural healing response.

The patient experience with the trial begins with a cell-potency screening test. Patients who qualify for therapy are scheduled for a bone-marrow aspiration. The bone marrow is then processed on-site and subsequently delivered directly to the damaged regions in a patient's heart in a minimally invasive procedure.

"Patients living with heart failure experience a variety of negative symptoms that can greatly impact their day-to-day life," said UW Health cardiologist Dr. Amish Raval, associate professor of medicine and one of the principal investigators for the trial. "By being at the forefront of research for this debilitating condition, we look forward to studying the potential of this cell therapy to impact a patient's exercise capacity and quality of life."

The primary outcome to be measured is the change in distance during a six-minute walk 12 months after the initial baseline measurement.

Heart failure commonly occurs after a heart attack, when the heart muscle is weakened and cannot pump enough blood to meet the body's needs for blood and oxygen. About 790,000 people in the U.S. have heart attacks each year. The number of adults living with heart failure increased from about 5.7 million (2009-2012) to about 6.5 million (2011-2014), and the number of adults diagnosed with heart failure is expected to dramatically rise by 46 percent by the year 2030, according to the American Heart Association (AHA).

The CardiAMP Heart Failure Trial is a phase III study of up to 260 patients at up to 40 centers nationwide. Phase III trials are conducted to measure effectiveness of the intervention, monitor side effects and gather information for future use of the procedure. Study subjects must be diagnosed with New York Heart Association (NYHA) Class II or III heart failure as a result of a previous heart attack.

Information about eligibility or enrollment in the trial is available at http://www.clinicaltrials.gov, or through a cardiologist.

First participant treated in trial of stem-cell therapy for heart failure - Medical Xpress

Like drag car racers revving their engines at the starting line, stem cells respond more quickly to injury when they've been previously primed with one dose of a single protein, according to a study from the Stanford University School of Medicine.

Mice given the priming protein recover muscle function more quickly after damage, their skin heals more rapidly and even the shaved area around the injury regrows hair more quickly, the study found. Harnessing the power of this protein may one day help people recover more quickly from surgery or restore youthful vigor to aging stem cells.

"We're trying to better understand wound healing in response to trauma and aging," said Thomas Rando, MD, PhD, professor of neurology and neurological sciences. "We've shown that muscle and bone marrow stem cells enter a stage of alertness in response to distant injury that allows them to spring into action more quickly. Now we've pinpointed the protein responsible for priming them to do what they do better and faster."

Rando, who also directs Stanford's Glenn Center for the Biology of Aging, is the senior author of the study, which will be published April 18 in Cell Reports. Former postdoctoral scholar Joseph Rodgers, PhD, is the lead author. Rodgers is now an assistant professor of stem cell biology and regenerative medicine at the University of Southern California.

Potential therapy

"Our research shows that by priming the body before an injury you can speed the process of tissue repair and recovery, similar to how a vaccine prepares the body to a fight infection," Rodgers said. "We believe this could be a therapeutic approach to improve recovery in situations where injuries can be anticipated, such as surgery, combat or sports."

Normally, adult, tissue-specific stem cells are held in a kind of cellular deep freeze called quiescence to avoid unnecessary cell division in the absence of injury. In a 2014 paper published in Nature, Rodgers and Rando showed in laboratory mice that an injury to the muscle of one leg caused a change in the muscle stem cells of the other leg. These cells entered what the researchers called an "alert" phase of the cell cycle that is distinct from either fully resting or fully active stem cells.

The fact that muscle stem cells distant from the injury were alerted indicated that the damaged muscle must release a soluble factor that can travel throughout the body to wake up quiescent stem cells. Rodgers and his colleagues found that a protein called hepatocyte growth factor, which exists in a latent form in the spaces between muscle cells and tissue, can activate a critical signaling pathway in the cells by binding to their surfaces. This pathway stimulates the production of proteins important in alerting the stem cells. But it wasn't known how HGF itself became activated.

In the new study, Rodgers and his colleagues identified the activating factor by injecting uninjured animals with blood serum isolated from animals with an induced muscle injury. (Mice were anesthetized prior to a local injection of muscle-damaging toxin; they were given pain relief and antibiotics during the recovery period.) After 2.5 days, the researchers found that muscle stem cells from the recipient animals were in an alert state and completed their first cell division much more quickly than occurred in animals that had received blood serum from uninjured mice.

"Clearly, blood from the injured animal contains a factor that alerts the stem cells," said Rando. "We wanted to know, what is it in the blood that is doing this?"

Increased levels of a protein

The researchers found that the serum from the injured animals had the same levels of HGF as the control serum. However, it did have increased levels of a protein called HGFA that activates HGF by snipping it into two pieces. Treating the serum with an antibody that blocked the activity of HGFA eliminated the recovery benefit of pretreatment, the researchers found.

In a related experiment, exposing the animals to a single intravenous dose of HGFA alone two days prior to injury helped the mice recover more quickly. They scampered around on their wheels sooner and their skin healed more quickly than mice that received a control injection. They also regrew their hair around the shaved surgical site more completely than did the control animals.

"Just like in the muscles, we saw the responses in the skin were dramatically improved when the stem cells were alerted," Rando said.

In addition to pinpointing possible ways to prepare people for surgeries or other situations in which they might sustain wounds, the researchers are intrigued by the role HGF and HGFA might play in aging. It's known that the pathway activated by these proteins is less active in older people and animals.

"Stem cell activity diminishes with advancing age, and older people heal more slowly and less effectively than younger people. Might it be possible to restore youthful healing by activating this pathway?" said Rando. "We'd love to find out."

The work is an example of Stanford Medicine's focus on precision health, the goal of which is to anticipate and prevent disease in the healthy and precisely diagnose and treat disease in the ill.
