"The impact of Alzheimer's disease is vast, far exceeding the medical community's current ability to treat it," said Joshua M. Hare, M.D., Longeveron's Co-Founder and Chief Science Officer. "Regenerative medicine and cell-based therapies offer a promising new approach to close this gap and address the urgent need for effective therapies to combat the condition."

An important component in the progression of Alzheimer's disease is neuroinflammation. Longeveron was recently awarded a $1 million Part the Cloud Challenge on Neuroinflammation grant from the Alzheimer's Association to help support this research.

"Adult stem cells are very potent anti-inflammatories. The characteristic amyloid plaques found in the brains of Alzheimer's disease patients produce inflammation, and stem cells can reduce inflammation," explained Bernard S. Baumel, M.D., Principal Investigator for the trial. "Alzheimer's also impairs the brain's ability to adequately produce new brain cells in the memory area known as the hippocampus. Stem cells can stimulate the brain to produce these new cells needed to form memory. We believe that an infusion of LMSCs may improve the condition or at least halt the progression of the disease."

Prior research shows that adult MSCs target and reduce inflammation, promote tissue repair and improve brain function in mouse models of Alzheimer's disease. Longeveron's trial is the first U.S. clinical study of exogenously administered mesenchymal stem cells derived from the bone marrow of healthy adult donors for treating Alzheimer's disease.

Adam Krief, with his wife, Lia, had a rare form of blood cancer that proved to be fatal. (Facebook)

(JTA) Adam Krief, a Jewish cancer patient whose search for a bone marrow donor captured the attention of social media and celebrities including Kim Kardashian, Mayim Bialik and Jason Biggs, has died.

Krief, a father of three from Los Angeles, died Tuesday, a family friend confirmed to JTA. He was 32.

Krief was diagnosed with primary myelofibrosis, a rare form of blood cancer that is likely fatal if a stem celltransplant matchis notfound.To find anHLA, or gene complex matchfor Krief something more difficultto track downthan a blood type match drives were held around the world, including in North America,Israel, France and Mexico.

Kardashian posted about Krief on Facebook in September, saying he was a friend of a friend.

A bone-marrow donor was found last December seven matches were found, in fact, through the donor drives organized for him.

This is what cloud 9 looks like Im so grateful to let you all know that a donorhas been found, Krief wrote at the time, sharing a video with two of his children.

The Hope 4 Adam Facebook page on March 8 called for a Worldwide Unity Shabbat for March 11 and March 18 for the recovery of Krief, asking followers to Help us bring about a miracle.

On Monday, the Eretz Kabbalah Facebook page of the Los Angeles-based Eretz Cultural Center posted a call for followers to recite Tehillim, or psalms, on behalf of Krief.

After a long search for a bone-marrow match to save his life, he finally received one. However, after some complications, he is said to only have a few hours to live, the post said.

Krief is survived by his wife, Lia, and his young children.

A longtime product developer is bringing a peptide ingredient to the US market that has been researched for a unique property promoting the growth of bone marrow stem cells.

Called DH Stemogen, the product is the brainchild of Dr Marvin Heuer MD who has a history of product development with sports nutrition company MuscleTech. Dr. Heuer has a background in clinical research, having spent many years in drug development at Glaxo Smith Kline. He also runs a contract research firm, Heuer M.D. Research Inc. and is the CEO of omega-3 supplement manufacturer Blue Ocean Nutrascience.

The new product, called DH Stemogen is based on a Cyclo-{L-ALA-L-GLU(TRP-OH) peptide that was developed by a Russian biochemist.

Its a peptide that is a mimic of a naturally occurring thymic peptide,Dr. Heuer told NutraIngredients-USA. Heuer was promoting the launch of the product at the recent Expo West trade show in Anaheim, CA. At Heuer M.D. Research, as a company we are out looking for novel ingredientsto bring out, hopefully in the nutraceutical area.

We got interested in Prof. Vlad Deigins peptide research, Dr. Heuer said (Deigin is associated with the Institute of Bioorganic Chemistry at the Russian Academy of Sciences in Moscow.)We looked at this particular compound that he was launching as an ingredient in Russia about a year ago.

The peptide in DH Stemogen targets a particular type of stem cell hematopoietic cells (HSC). Stem cells in general are the building blocks of our bodies. These cells are able to transform themselves into almost any type of cell. There are various sources of stem cells in an adult body. One of the most important of them comprises the bone marrow, where the HSCs are produced. HSCs transform into all the main cell types in our blood, including red blood cells and white blood cells. Dr. Heuer said there is some evidence that those cells are able to reconstruct other body tissues by transforming into the specific tissue type cell such as liver, nervous tissue, kidney and skin.

These properties would seem to make Stemogen a natural for a healthy aging product positioning, Dr. Heuer said. But Deigins research, trending as it does over into disease endpoints, is a little problematical when it comes to supporting US-style structure function claims, he admitted. Other countries dont make the same hard and fast distinctions between dietary ingredients meant for supplement applications and active pharmaceutical agents meant for drugs, he said.

We are going to be very cautious about making structure/function claims,Dr. Heuer said. The product at the moment saysSupport your immune system and Support healthy levels of stem cells in your blood.

We are about to begin a whole profile of research in the U.S. and Canada, he added.

Dr. Heuer said one thing thats unique about the ingredient (and something that he says Deigin has patented) is a structural twist that improves the peptides stability. The criticism of some other novel peptides has been that interesting as their properties might be, once they hit the stomachs gastric fluid they blow apart into their constituent amino groups and all those novel properties are lost.

He has a patent on the way he makes this with a hex ring on the end that protects it in the GI tract and allows it to be absorbed,he said.

Bringing a synthetic analogue of a naturally occurring peptide to market as a dietary ingredient would seem to pose significant regulatory challenges. Dr. Heuer said hes confident there is a way through that thicket. The plan is to start first with a GRAS filing, and Dr. Heuer said he believes that the peptide would fall under the amino acid category in the DHSEA definitions of what constitutes a dietary ingredient.

Certainly there is a precedent of complex peptides being sold on the market, he said.

The first new finding is an obvious onethe mouse experiments worked in human cells. Just because something worked in mice doesn't necessarily mean it will work in people too. So this is a really important finding.

The second important finding has to do with the specific genes each group used. Both groups added four genes to turn a stem cell into an ES cell. But they used a slightly different set of genes.

The Japanese group added OCT3/4, SOX2, KLF4, and c-MYC. The Wisconsin group added OCT4, SOX2, NANOG, and LIN28. This matters because of a side effect seen in the previous mouse study.

The mouse study went farther than the human study in that the researchers added these new ES cells to a mouse embryo. The results were disconcerting. Around 20% of the mice developed cancer from the cells. The researchers hypothesized that the cause was one or more of the genes that were used to create the ES cell.

By using different sets of genes in the human cell study, the researchers showed you don't need the same four genes to create an ES cell. The hope is that the researchers will find a combination of genes that do not cause cancer.

Once the scientists find a set of genes that don't cause cancer, this research should blow the stem cell field wide open. We still don't know if ES cells will work to actually cure disease. But ethical ES cells should open the spigot of federal funds so American scientists can finally research this subject to its full extent. Then we'll see if ES cells can really live up to their hype. Or if we need to pursue other ways to cure these illnesses.

Human Embryonic Stem (ES) Cells from Skin Cells ...

Skin Stem Cells Comments Off on Human Embryonic Stem (ES) Cells from Skin Cells … | March 15th, 2017

March 15, 2017 by Grove Potter The four images, from left to right, show Keratinocyte-derive neural crest stem cells turning into neurons as shown by typical neuronal morphology. Credit: University at Buffalo.

A discovery, several years in the making, by a University at Buffalo research team has proven that adult skin cells can be converted into neural crest cells (a type of stem cell) without any genetic modification, and that these stem cells can yield other cells that are present in the spinal cord and the brain.

The practical implications could be very significant, from studying genetic diseases in a dish to generating possible regenerative cures from the patient's own cells.

"It's actually quite remarkable that it happens," says Stelios T. Andreadis, PhD, professor and chair of UB's Department of Chemical and Biological Engineering, who recently published a paper on the results in the journal Stem Cells.

The identity of the cells was further confirmed by lineage tracing experiments, where the reprogrammed cells were implanted in chicken embryos and acted just as neural crest cells do.

Stem cells have been derived from adult cells before, but not without adding genes to alter the cells. The new process yields neural crest cells without addition of foreign genetic material. The reprogrammed neural crest cells can become smooth muscle cells, melanocytes, Schwann cells or neurons.

"In medical applications this has tremendous potential because you can always get a skin biopsy," Andreadis says. "We can grow the cells to large numbers and reprogram them, without genetic modification. So, autologous cells derived from the patient can be used to treat devastating neurogenic diseases that are currently hampered by the lack of easily accessible cell sources."

The process can also be used to model disease. Skin cells from a person with a genetic disease of the nervous system can be reprogrammed into neural crest cells. These cells will have the disease-causing mutation in their chromosomes, but the genes that cause the mutation are not expressed in the skin. The genes are likely to be expressed when cells differentiate into neural crest lineages, such as neurons or Schwann cells, thereby enabling researchers to study the disease in a dish. This is similar to induced pluripotent stem cells, but without genetic modification or reprograming to the pluripotent state.

The discovery was a gradual process, Andreadis says, as successive experiments kept leading to something new. "It was one step at a time. It was a very challenging task that took almost five years and involved a wide range of expertise and collaborators to bring it to fruition," Andreadis says. Collaborators include Gabriella Popescu, PhD, professor in the Department of Biochemistry in the Jacobs School of Medicine and Biomedical Sciences at UB; Song Liu, PhD, vice chair of biostatistics and bioinformatics at Roswell Park Cancer Institute and a research associate professor in biostatistics UB's School of Public Health and Health Professions; and Marianne Bronner, PhD, professor of biology and biological engineering, California Institute of Technology.

Andreadis credits the persistence of his then-PhD student, Vivek K. Bajpai, for sticking with it.

"He is an excellent and persistent student," Andreadis says. "Most students would have given up." Andreadis also credits a seed grant from UB's office of the Vice President for Research and Economic Development's IMPACT program that enabled part of the work.

The work recently received a $1.7 million National Institutes of Health grant to delve into the mechanisms that occur as the cells reprogram, and to employ the cells for treating the Parkinson's-like symptoms in a mouse model of hypomyelinating disease.

"This work has the potential to provide a novel source of abundant, easily accessible and autologous cells for treatment of devastating neurodegenerative diseases. We are excited about this discovery and its potential impact and are grateful to NIH for the opportunity to pursue it further," Andreadis said.

The research is described in the journal Stem Cells under the title "Reprogramming Postnatal Human Epidermal Keratinocytes Toward Functional Neural Crest Fates."

Skin Stem Cells Comments Off on From skin to brain: Stem cells without genetic modification – Phys.Org | March 15th, 2017

RenovaCare Inc. (OTCQB:RCAR) is a New York City-based biotechnology company developing its patented CellMist and SkinGun stem cell technologies for treating burns in weeks or less as well as treating chronic and acute wounds, acne scarring, and skin defects and diseases. In December, it received a U.S. patent for its SkinGun device.

Before joining RenovaCare, CEO Thomas Bold was CEO of StemCell Systems. He has more than 15 years of experience in medical biotechnology device manufacturing and stem cell platform development.

Harlan Levy: How does your CellMist technology specifically work?

Thomas Bold: Doctors isolate a high concentration of the most desirable stem cell population from a very small donor sample of the patient's own skin and suspended in the liquid CellMist Solution. It's then gently sprayed onto wound sites using our SkinGun, which looks like Captain Kirk's particle-beam gun, the "Phaser" in the Star Trek TV series.

The isolated cells include cells that proliferate rapidly in order to achieve quick re-epithelialization. This is the stage at which a burn is technically considered "healed" and patients are often discharged. The average person would recognize this healing phase as the point at which the wound develops a thin, shiny, pink-colored protective layer.

H.L.: What are existing burn treatments, and how do they compare with the SkinGun treatment?

T.B.: Traditional skin grafting has been the treatment for burns and wounds for centuries. More recently, mesh grafting has become the latest standard of care. This process surgically removes large sheets of healthy skin from the patient. Following this painful donor procedure, the sheet is punctured in a grid-like pattern to form an expandable mesh. Surgeons pull this mesh as wide as feasible and surgically stitch this skin to the patient's wound. The procedure is extremely painful, creates an additional wound at each donor site and results in poor cosmetic outcomes, often with scarred and deformed skin.

This transplanted skin can result in restricted joint movement and is unable to grow with the patient. Consequently, mesh graft patients require months and sometimes up to a year of physical therapy and can face psychological problems from the permanent disfigurement of scarring. In addition, long-term pain management with painkillers is very often necessary.

With the RenovaCare treatment technology, by spraying the patient's stem cells, the SkinGun overcomes the need for removing large sheets of donor skin, and the resultant healing does not require prolonged physical therapy. The spray procedure is gentle, and the skin that regrows looks, feels, and functions as the original skin that it replaces. Most often the healing process takes only a week.

It's very important to note here that a sheet of meshed skin covers only up to six times its original donor area. The RenovaCare system covers up to 100 times its donor skin sample. This is why the donor skin sample can be so small compared to the injured treatment area.

H.L.: What about scars and infection potential compared with conventional treatments?

T.B.: A wound heals from the edges towards the middle. The bigger the wound, the longer this process takes. And the longer this process takes, the higher the risk of infection and scarring.

Imagine a large burn of 20, 30, 40 percent of your total body surface. With our CellMist System, the doctor sprays the patient's own stem cells with a highly regenerative capacity onto the wound and, by doing so, creates tens of thousands of little regenerative islands across the wound. These islands grow outwards, ultimately connecting to each other to create a protective epithelial skin layer that covers the wound.

Experts believe the formation of this pink-colored layer marks the moment of re-epithelization where the risk of infection is reduced and the patient's wound is effectively healed. Beyond this stage, the cosmetic healing process also happens entirely natural to produce a scar-free result where, finally, skin color, tone and pigmentation are restored.

Since the RenovaCare spray procedure uses the patient's own stem cells, there isn't the risk of tissue rejection, infection, or ongoing immuno suppression therapy.

H.L.: What results have you found for patients using the SkinGun?

T.B.: We have many examples of patients recovering from severe burns within a week or two, scar-free, and walking away with unlimited joint restrictions.

In the case of one patient with severe electrical burns to over a third of his body, we were able to spray his wounds with 23 million stem cells isolated from a tiny two-inch-by two-inch sample of his own skin. Within five days of treatment, his chest and arms were already healed. Four days later, the patient was discharged from the hospital.

It's also important to note that reconstructive surgery for burn patients is especially challenging when tackling joints in the body. To this end, the authors of a case study in the reputable journal "Burns," said, "Cell-spray grafting is also especially suitable for hands and joint areas, where prolonged times to re-epithelization may significantly impact functionality and esthetic outcome."

H.L.: What different uses does the SkinGun have beside burns?

T.B.: Currently, we are focusing on severe second-degree burns, but we see the RenovaCare technology also applicable for other indications such as cosmetic procedures targeting skin pigmentation disorders, scar treatment, and other related conditions.

Our goal is to bring to market the world's most advanced technology for skin repair using a patient's own stem cells.

H.L.: Is there a record of the SkinGun use in the States and abroad?

T.B.: Having treated 72 burn patients to date, the company's early clinical target is burns with follow-on indications, including chronic wounds and cosmetic procedures.

H.L.: How much research went into creating the SkinGun and over what time period?

T.B.: The birth of RenovaCare technology goes back to the early 2000s in Berlin, Germany. Researchers, at that time, were trying to "grow" skin by seeding stem cells inside multi-dimensional bioreactors. They soon discovered that these artificial chambers were no match for the growth of the same cells when transplanted inside a human body; thus, the birth of a concept to use a patient's own wound as a natural bioreactor.

A study published in "Advances in Plastic Surgery" highlights 19 early patients with deep dermal wound burns to the face and neck, complex three-dimensional surfaces. Researchers achieved such outstanding results using our cell spray that they refused to perform further skin grafting. Instead, surgeons adopted our founding technology as their standard of care.

Let me quote from the surgeons' study, which states

"We refuse to perform a prospective randomized study with groups in which traditional skin grafting and/or wound healing are still applied for the therapy for deep dermal burns due to the excellent results in our study. The method of CEA spray application has become our standard of care for these indications. The faster wound closure, the promotion of spontaneous wound healing by keratinocyte application, as well as the preservation of donor sites are further advantages of the method."

The same paper concluded that "using a spray technique results in excellent cosmetic outcomes compared with any other method."

H.L.: How has the technology changed since then?

T.B.: Since the time of this early approach, our technology has evolved and matured significantly. Our cell isolation no longer requires complex procedures, culturing, expansion, and processing time, and our stem cell spray device no longer requires multiple hand-assembled parts. Its independent power and flow-control unit has been condensed in size from a 2-foot cube down to a 9-volt battery placed inside the handle of a single handheld spray gun.

H.L.: What is the potential market for the technology in dollars and number of patients?

T.B.: Conservatively speaking, the market for our technology exceeds $50 billion. There are nearly a million people who suffer from burns each year in the U.S. alone. According to the American Burn Association, burn injuries continue to be one of the leading causes of accidental death and injury in the U.S, and one civilian fire death occurs every two hours and forty minutes.

H.L.: How much would you estimate the treatment cost may be for each different use?

T.B.: The SkinGun technology is currently under development and not approved for clinical use in the U.S., so it's too early to talk about what the treatment will cost. We have always been mindful of reimbursement, and nearly two years ago, we commissioned an investigation into the reimbursement pathway for our CellMist System. We know that reimbursement opportunities are available by way of current coding and practices.

We have further investigated and evaluated the "bundling" approach currently advocated for by insurers and are confident that that our technology is well placed to take advantages of any shift towards such a model.

H.L: What is the schedule to get Federal Drug Administration clearance?

T.B.: In order to achieve FDA clearance for the CellMist System and the SkinGun, we will be working to show our technology is safe and prove its efficacy within applicable clinical trial formats and according to the relevant regulatory requirements. I can't speculate as to how long the FDA clearance process will take, and, therefore, it's hard to speculate when our product will be commercialized.

H.L.: What other products are you investigating and how may they work?

T.B.: We are focusing on bringing the SkinGun and our stem cell spray technology to market at this time.

H.L.: What is your background, including age, education, prior employment?

T.B.: Before joining RenovaCare I worked as the CEO of StemCell Systems GmbH, a Berlin-based biomedical company engaged in the development and commercialization of advanced cell culture bioreactors. I have more than 15 years of professional business experience in the field of medical biotechnology device manufacturing, stem cell culture technology platform development and regenerative medicine research project management and product development. I also co-founded several start-up companies in Germany.

Stem cells are unspecialised cells that can develop into any type of cell in the human body. So far, however, scientists only partially understand how the body controls the fate of these all-rounders, and what factors decide whether a stem cell will differentiate, for example, into a blood, liver or nerve cell. Researchers from the Luxembourg Centre for Systems Biomedicine (LCSB) of the University of Luxembourg and an international team have now identified an ingenious mechanism by which the body orchestrates the regeneration of red and white blood cells from progenitor cells. "This finding can help us to improve stem cell therapy in future," says Dr. Alexander Skupin, head of the "Integrative Cell Signalling" group of LCSB.

Although all cells in an organism carry the same genetic blueprints the same DNA some of them act as blood or bone cells, for example, while others function as nerve or skin cells. Researchers already understand quite well how individual cells work. But how an organism is able to create such a diversity of cells from the same genetic template and how it manages to relocate them to wherever they are needed in the body is still largely unknown. In order to learn more about this process, Alexander Skupin and his team treated blood stem cells from mice with growth hormones and then watched closely how these progenitor cells behaved during their differentiation into white or red blood cells. The researchers observed that the cells' transformation does not occur in linear, targeted fashion, but rather more opportunistically. Each progenitor cell adapts to the needs of its environment and integrates itself into the body where new cells are needed. "So, it is not as though the cell takes a ticket at the beginning of its differentiation and then travels straight to its destination. Rather, it gets off frequently to look around and see which line is best to take," Alexander Skupin explains.

By this clever mechanism, a multicellular organism can adapt the regrowth of new cells to its current needs. "Before progenitor cells differentiate once and for all, they first lose their stem cell character and then check, as it were, which cell line is currently in demand. Only then do they develop into the cell type that best suits their characteristics and which prevails in their environment," Alexander Skupin says. The researcher likens this step to a game of roulette, where the different types of cells can be thought of as the differently numbered slots in the roulette wheel that catch the ball. "When the cells lose their stem cell character, they are quasi thrown into the roulette wheel, where they first bounce around aimlessly. Only when they have found the right environment do the cells then drop into that niche like the roulette ball falling into a numbered slot and differentiate definitively." This way, the body can orchestrate its cell regeneration and at the same time prevent stem cells from being misdirected too early. "Even if a cell takes a wrong turn, it is ultimately sorted out again if its characteristics are unsuitable for the niche, or slot, it has landed in," says Skupin.

With their study, Alexander Skupin and his team have shown for the first time that a progenitor cell's fate is not clearly predetermined and does not follow a straight line. "This observation contradicts the current doctrine that stem cells are programmed to follow a certain lineage from the beginning," Alexander Skupin says. The researcher is furthermore convinced that the processes are similar for other progenitor cells. "In the lab, we have observed the same differentiation pattern in so-called iPS cells, or induced pluripotent stem cells, which can transform into many different types of cells."

This knowledge can help the researchers to improve the effectiveness of therapies in future. Stem cell therapy involves administering a patient his or her own body's stem cells in order to replace other cells that have died as a result of an affliction such as Parkinson's disease. While this promising treatment method has been intensively researched over many years, there has so far been only limited practical success in endogenous stem cell therapy. It is also highly controversial, since it is frequently accompanied by severe side effects and it cannot be ruled out that some cells might degenerate and lead to cancer. "Because we now have a better understanding of how the body influences the direction in which stem cells differentiate, we can hopefully control this process better in future," Alexander Skupin concludes.

Skin Stem Cells Comments Off on Antibody Therapy Targets Cancer Stem Cells: Study – The Scientist | March 15th, 2017

Guiding a recent tour of a Kyoto University lab, a staff member holds up a transparent container. Inside are tiny pale spheres, no bigger than peas, floating in a clear liquid. This is cartilage, explains the guide, Hiroyuki Wadahama. It was made here from human iPS cells.

A monitor attached to a nearby microscope shows a mass of pink and purple dots. This is the stuff from which the cartilage was grown: induced pluripotent stem cells, often called iPS cells. Scientists can create these seemingly magical cells from any cell in the body by introducing four genes, in essence turning back the cellular clock to an immature, nonspecialized state. The term pluripotent refers to the fact iPS cells can be reprogrammed to become any type of cell, from skin to liver to nerve cells. In this way they act like embryonic stem cells and share their revolutionary therapeutic potentialand as such, they could eliminate the need for using and then destroying human embryos. Also, iPS cells can proliferate infinitely.

They can also give rise, however, to potentially dangerous mutations, possibly including ones that lead to cancerous tumors. Thus, iPS cells are a double-edged swordtheir great promise is tempered by risk. Another problem is the high cost of treating a patient with his or her own newly reprogrammed cells. But now Japanese researchers are trying a different approach.

When Kyoto University researcher Shinya Yamanaka announced in 2006 that his lab had created iPS cells from mouse skin cells for the first time, biologists were stunned. In 2007, along with James Thomson of the University of WisconsinMadison, Yamanaka repeated the feat with human skin cells. Many hailed the opening of an entirely new field of personalized regenerative medicine. Need new liver cells? No problem. Patients could benefit from having their own cells reprogrammed into ones that could help treat disease, potentially eliminating the prospect of immune rejection. In 2012 Yamanaka shared the Nobel Prize in Physiology or Medicine with John Gurdon for discovering that mature cells can be converted to stem cells. By reprogramming human cells, scientists have created new opportunities to study diseases and develop methods for diagnosis and therapy, the Nobel judges wrote. To capitalize on the discovery, Kyoto University set up the $40-million Center for iPS Cell Research and Application (CiRA), which Yamanaka directs.

A decade after the Yamanaka teams groundbreaking discoveries, however, iPS cells have retreated from the headlines; to the layperson, progress seems scant. There has only been one clinical trial involving iPS cells, and it was halted after a transplant operation on just one patienta Japanese woman in her 70s with macular degeneration, a condition that can lead to blurry vision or partial blindness. Doctors at Kobe City Medical Center General Hospital used her skin cells to grow iPS cells, which were reprogrammed into retinal cells and implanted in her eye. The treatment stopped the degeneration but the trial was halted in 2015 because genetic mutations were detected in another batch of iPS cells intended for another patient. Regulatory changes, under which the Japanese government allowed the distribution of iPS cells for clinical use, also prompted researchers to switch the study to a more efficient process of using cells from third-party donors instead of using a patients own cells. The Japanese government has a lot of incentives to considerwere developing a new science, a new technology and also a new economic market, says CiRA spokesperson Peter Karagiannis. So theres the ethical issues, but theres also money to be made. How do we balance the two?

The Kobe clinical trial had a lot riding on it. And the setback followed a major stem cell scandal in which biologist Haruko Obokata of the Riken Center for Developmental Biology was found to have falsified data in studies, published in 2014, that claimed a new method of achieving pluripotency. Then, earlier this year, Yamanaka had to apologize at a news conference after it was discovered that a reagent used to create iPS cells at CiRA was mislabeled, which could mean the wrong reagent was used. Although the mix-up is being examined, the center has halted supplies of some of its iPS cells to researchers across Japan; the error also set back by a few years a CiRA project to produce clinical-grade platelets from iPS cells.

But Yamanaka says he remains focused on the bigger picture of iPS cells and is still optimistic they can not only help researchers but may be key to transformative clinical therapies. CiRA still has a bank of tens of millions of iPS cells that have already been reset and checked for safety, so they can be used in patient applications. In terms of regenerative medicine, things have gone quicker than I expected, Yamanaka says, adding, iPS cells have exceeded expectations because of their potential for disease modeling, which allows us to elucidate unknown disease mechanisms, and drug discovery.

Those hoping for quick clinical success should remember it takes time for revolutionary treatments to go from lab bench to bedside, says Andras Nagy, a stem cell researcher at Mount Sinai Hospitals LunenfeldTanenbaum Research Institute in Toronto, who has not been directly involved in Yamanakas work. If you fully appreciate the paradigm-shifting nature of iPS cells, tremendous progress has in fact been made over the past 10 years, says Nagy, who in 2009 established a method of creating stem cells without using viruses (which had initially been used to deliver reprogramming genes into targeted cells). By comparison, penicillin was discovered as an antibiotic in 1928, but it was not available in the clinic until the early 1940s.

Researchers in Japan are meanwhile using iPS cell technology to pave the way to better drugs. For instance, CiRAs Kohei Yamamizu recently reported developing a cellular model of the bloodbrain barrier made entirely from human iPS cells. It could become a useful tool for testing drugs for brain diseases.

All eyes, however, are back on Kobe City Medical Center General Hospital, which is resuming its retina trialthis time with iPS cells from donors instead of cells from patients themselves. Using CiRAs bank of iPS cells, there are significant time and cost savingsit could be one fifth the cost of cell preparation and patient transplant or less. The initial study, with its personalized approach, reportedly cost about $875,000 for just one patient. We plan to evaluate the efficacy of transplanting the [donor] cells and consider the feasibility of using this method as a routine treatment in the future, accessible to the wider society, study co-leader Masayo Takahashi of the RIKEN Center for Developmental Biology said at a February press conference in Kobe. Her husband Jun Takahashi, a researcher at CiRA, is also planning to use donor-derived iPS cells for a clinical applicationto help treat patients with Parkinsons disease.

Nagy admits the promise of personalized cell regeneration is probably too costly for mainstream use, and he believes genomic editingin which DNA is inserted or deletedis key to safe iPS cell implants. For his part, Yamanaka is cautiously optimistic about iPS cells as a therapeutic tool.

Regenerative medicine and drug discovery are the two key applications for iPS cells, Yamanaka says. With the use of iPS cell stock, we are now able to work quicker and cheaper, so thats the challenge going forward.

Heptares struck a $12 million deal to partner with Daiichi Sankyo on a new GPCR pain drug. The UK biotech gets $4 million upfront and $8 million in research support along with an unspecified set of milestones for the deal, in which the Sosei subsidiary will search for new drugs that can be developed for pain. Said CEO Malcolm Weir: We are confident that the unique structural insights of the receptor that our technologies can deliver combined with expertise on its role in pain from the Neurosciences team at Daiichi Sankyo will yield new, differentiated molecules that can be advanced into development.

Everybody loves a good takeover rumor. On Friday, it was Incytes turn again. The biotechs shares jumped Friday on buzz that Gilead was interested in acquiring the company, fast on the heels of an analysts report insisting that Gilead needed to do a deal, fast.

Belgiums TiGenix says that it gained some positive data in a Phase I/II cardiac stem cell study. Investigators say that a pre-specified subset of patients demonstrated a larger reduction in infarct size. This is the first trial in which it has been demonstrated that allogeneic cardiac stem cells can be transplanted safely through the coronary tree, and in the worst possible setting represented by patients with an acute heart attack with left ventricular dysfunction, commented Professor Fernndez-Avils, head of the Department of Cardiology at the Hospital General Universitario Gregorio Maran.

VANCOUVER, BRITISH COLUMBIA--(Marketwired - March 13, 2017) -

NOT FOR DISSEMINATION IN THE UNITED STATES

Editors Note: There is a photo associated with this press release.

Woodrose Ventures Corporation (TSX VENTURE:WRS.H) ("Woodrose" or the "Company") is pleased to announce that it has entered into an agreement (the "Agreement") dated March 10, 2017 to acquire all of the shares of Novoheart Holdings Ltd. ("Novoheart"), a global stem cell biotechnology company dedicated to human heart engineering (the "Transaction"). Novoheart develops products and provides services focused on engineering prototypes of bio-artificial human heart tissues and chambers for drug discovery, cardiotoxicity screening, disease modelling and therapeutic applications.

The Transaction will constitute a "reverse-takeover" of Woodrose in accordance with the policies of the TSX Venture Exchange (the "TSXV") and the reactivation of Woodrose, which is currently a NEX-listed issuer.

About Novoheart

Novoheart is a global stem cell biotechnology company headquartered in Hong Kong with R&D Innovation Centres being set up in the United States. Novoheart's mission is to revolutionize drug discovery and the development of heart therapeutics with its range of proprietary bioengineered human heart constructs, collectively known as the MyHeart platform, and to further develop them into transplantable heart grafts for cell-based regenerative therapies with superior safety and efficacy. Its scientific team has pioneered a range of best-in-class bioengineering technologies and constructed the world's first human mini-heart "novoHeart" with which the Novoheart team intends to revolutionize:

1) Pre-clinical drug discovery, cardiotoxicity screening and heart disease modelling;

2) Post-discovery, clinical development of novel therapeutics; and

3) Pre-clinical and clinical development of cell-based cardiac regenerative therapies.

Novoheart's immediate focus is to innovate and accelerate the lengthy, expensive and inefficient drug development process. The development of a new drug candidate typically costs US$2-4bn and takes 10+ years (Tufts Centre for the Study of Drug Development, Tufts CSDD R&D Cost Study 2014) with extremely poor success rates of <1% of initial drug candidates making it to market (Willmann et al. 2008, Nature Reviews Drug Discovery 7, 591-607). The primary cause for drug withdrawal and attrition is heart toxicity. Despite substantial pre-human R&D costs (~30% of the entire process), conventional non-human and non-cardiac cell and animal models are poorly predictive of human responses, leading to false negative and false positive pre-clinical results that compromise the overall successes (Chen et al. 2016, Nature Reviews Cardiology 13, 333-349).

Novoheart's intellectual property portfolio, including the human "heart-in-a-jar" (novoHeart) and other related next-generation technologies of the MyHeart platform (see figure below) are unique solutions that help bridge the gap between pre-clinical and clinical drug trials. The MyHeart platform provides advanced human heart surrogates for pre-screening of drug formulas and the elimination of toxic compounds early on in the drug development process, minimizing the risk towards patients. Significantly, the MyHeart Platform provides real time data on the effects of drug formulations enabling drug development companies to undertake "on-the-fly" reformulation of drug candidates to optimize efficacy and toxicological profiles. With Novoheart's technologies, we aim to significantly reduce pre-clinical R&D time and costs, and importantly, improve trial successes. It is anticipated that drug screening results using Novoheart's human engineered tissues would be accepted as reliable indicators for toxicity and efficacy, thereby qualifying the test compounds for accelerated drug development.

Novoheart adopts a hybrid business model by:

These products and services are designed to significantly reduce the time, cost, and use of animal models, as well as improve patient safety, and facilitate pharmaceutical discovery and development. Novoheart is currently working with leading academic and pharmaceutical partners to innovate drug discovery and toxicity screening protocols. Our targeted clients are pharmaceutical companies, government units, and research institutions.

Novoheart was incorporated in 2014 pursuant to the laws of British Virgin Islands (BVI) and its controlling shareholder is Medera Group Limited, a BVI entity. Novoheart has one wholly owned Hong Kong subsidiary "Novoheart Limited" ("Novoheart Hong Kong") which is the group operating entity.

Novoheart Hong Kong was incorporated in January 2014 by founder and CEO Prof. Ronald Li, with scientific co-founders Prof. Kevin Costa and Prof. Michelle Khine.

Novoheart's foundational technologies are the direct outcome of over 15 years of research effort supported by R&D investments amounting to approximately USD30MM. These research efforts, performed at Johns Hopkins University, Icahn School of Medicine at Mount Sinai, University of California Irvine, University of California Davis, and the University of Hong Kong by our scientific founders, have received major recognitions such as American Heart Association's Best Study of 2005, Ground-breaking Study of 2006, and Late-breaking Studies of 2002, 2003, 2005 and 2007, and the Spirit of Hong Kong Innovating for Good Award in 2015. The "human-heart-in-a-jar" technology was selected by Google's Solve For X as a Moonshot Project in 2015.

Novoheart's scientific founders and advisors are renowned pioneering leaders in the stem cell and cardiac space, with a successful track record in developing and commercializing ground-breaking technologies. In September 2014, Novoheart established its R&D base and office in the Hong Kong Science Park, where it continues to innovate solutions for drug discovery and human heart tissue engineering.

In December 2014, Novoheart signed a strategic partnership with a major global pharmaceutical company (the "Global Pharma Partner") headquartered in New York City to validate the MyHeart platform. The success of this validation process has resulted in follow on income-generating projects.

In January 2015, Novoheart's R&D proposal to develop bio-artificial heart tissues for drug screening received 50/50 matched funding from the Innovation & Technology Commission (ITC) of the Government of Hong Kong, with a total project cost of over HK$21MM over 2 years. It was also the largest biotech project granted by ITC for that year. Novoheart owns all of the intellectual property generated from this project, and as a result of the R&D, Novoheart has applied or is in the application process for 3 new patents covering newly developed technology, including the human ventricular cardiac anisotropic sheet (hvCAS) as a powerful tool for detecting drug-induced arrhythmias with the results published in the prestigious international peer-reviewed bioengineering journal Advanced Materials (Shum et al. 2017, Advanced Materials, 29). Additionally, Novoheart holds exclusive worldwide licenses or options to acquire the same for technologies that constitute its MyHeart platform and future developments.

In December 2015, Novoheart signed a second contract with the Global Pharma Partner to build disease-specific engineered human heart tissues and chambers for drug discovery. The total project cost is US$726,000 over 1.5 years.

In February 2017, the Corporate Venture Fund (CVF) of the Hong Kong Science and Technology Parks Corporation (HKSTPC) completed an equity investment of approximately US$250,000 into Novoheart and an additional investment would be made at the Transaction.

Novoheart Financial Information

The following table includes a summary of certain financial information of Novoheart and is derived from its financial statements for the years ended June 30, 2016 and June 30, 2015.

Summary of the Transaction

Under the terms of the Agreement, the shareholders of Novoheart will receive an aggregate of 66,086,600 common shares of Woodrose on a post-Consolidation basis (see below) ("Woodrose Post-Consolidation Shares"). In addition, a finder's fee of 2,313,038 Woodrose Post-Consolidation Shares will be paid to Cynosure Private Equity Limited in connection with the Transaction.

In connection with the Transaction, Woodrose intends to complete a consolidation of all its outstanding common shares on the basis of 3.56878449 old common shares for each one new common share (the "Consolidation"). In addition, Woodrose intends to complete a non-brokered private placement (the "Private Placement") of 11,700,000 subscription receipts ("Subscription Receipts") at a price of CDN$0.50 per Subscription Receipt to raise gross proceeds of CDN$5,850,000, which will be held in escrow in accordance with the terms of a subscription receipt agreement (the "Subscription Receipt Agreement"). It is anticipated that the Subscription Receipt Agreement will provide that, upon completion of the Transaction, each Subscription Receipt will automatically convert into one Woodrose Post-Consolidation Share. The Subscription Receipt Agreement will also provide that, in the event the Transaction is terminated or does not complete within an agreed timeframe, the Subscription Receipts will be cancelled and the funds will be returned to the holders. Woodrose may pay cash fees in an amount not to exceed 7% of the gross proceeds (to a maximum of $364,000) to certain finders involved in the Private Placement and may issue finder's warrants ("Finder's Warrants"), in an amount not to exceed 7% of the number of Subscription Receipts issued (to a maximum of 728,000 Finders Warrants) each of which would entitle the holder to acquire one Woodrose Post-Consolidation Share at a price of CDN$0.50 for a period of two years following closing of the Private Placement. All securities issued pursuant to the Private Placement will be subject to a statutory hold period of four months and one day.

The Company intends to use the net proceeds of the offering to finance investment in drug discovery and screening, establish commercial partnerships, expand the current laboratory, hire additional research and development team members and for working capital and general corporate purposes.

Upon completion of the Transaction, it is anticipated that the Company will be classified as a Tier 2 Technology Issuer on the TSXV and will change its name to "Novoheart Holdings (BC) Limited" or such other name as is acceptable to the Board of Directors. Closing of the Transaction ("Closing") is subject to conditions precedent, that include, but are not limited to, the following:

PHILADELPHIA (CBS) Doctors at the University of Pennsylvania School of Veterinary Medicine are conducting a study to see if stem cell therapy will ease the pain of arthritis and the results of their research could benefit human patients as well.

Its Zoeys last check up,walking on a special mat called a forceplate to measure how much weight she puts on each leg.

It was just a year ago that putting weight on her front legs was painful.The 2-year-old Golden Retriever was diagnosed with elbow dysplasia, a condition that created arthritis in both elbows.

It is the most common cause of chronic pain in dogs, saidDr. Kimberly Agnello at Penn Vet.

Zoeys owner, Christine Brown, says she was a bundle of energy when she first got Zoey.

She was so sweet, said Brown. She was your typical energetic puppy.

But soon Brown knew her dog was hurting.

After coming back from a walk and taking a nap, she would get up and limp, said Brown. With her being a puppy it was devastating.

Zoey was enrolled in aPenn Vet trial to determine the benefits of stem cell therapy as a treatment to ease arthritic pain.

They are randomized into three groups, whether they receive an interarticular joint injection of hyaluronic acid or they geteither stem cells derived from their bone marrow or stem cells derived from fat, saidAgnello.

The stems cells from the dogs bone marrow are injected back into the elbow joint. Doctors hope it will relieve the arthritic pain.

We also remove a little fragment of bone that can be causing some more pain, saidAgnello.

The research isnt just about arthritis in dogs but humans as well.

The goals of this study are to look for different treatments to not only help our canine patientsbut also to help human patients with arthritis, saidAgnello.

For now results are promising.

Oh my gosh, she is not limping, she runs and jumps, and has a great time, said Brown.

The trial is ongoing so there is no hard data yet to show final results if stem cells are effective for treating arthritis, but Dr.Agnello says there are many dogs in the study and almost all of them have improved during the year-long research.

Veterinary Doctors Conduct Study Looking To Ease Arthritis Pain - CBS Philly

TiGenix announces positiveone-year results forits phase I/II trial of donor-derived cardiac stem cell therapy in acute myocardial infarction (AMI).

The Belgian biotech TiGenixis developing allogeneic stem cell therapies. Now the companyhasannouncedthat its cardiac stem cell therapyAlloCSC-01 reached its primary endpoints in aphase I/IItrial.

In 2015, the companyacquired Coretherapixin a292M deal for its allogeneic cardiac stem cell pipeline, which is being developed for the treatment of AMI.The first-in-human trial was designed to test the safety and feasibility of an intracoronary infusion of donor-derivedexpanded cardiac stem cells (AlloCSCs)in patients with AMI and left ventricular dysfunction.

AlloCSC-01consists of adult allogeneic cardiac stem cells isolated from the heartof donors and expanded in vitro. In vivo studies suggest that these cellshave cardio-reparative potential by activating regenerative pathways and promoting the formation of new hearttissue.

Thecurrent phase II study demonstrated thesafety of these allogeneic stem cells. Initial results also revealed a larger reduction of infarct size in a subgroup of patients.

Myocardial infarction caused by blockade of coronary arteries

TiGenix is well known forChondroCellect, which was the first cell therapyto reach the European market for the repair of knee cartilage.After the companyrecently withdrew its market authorization for this product, due to a lack of reimbursement, the biotech is focusing on another stem cell therapy, Cx601, in addition to AlloCSC-01. Under development for Crohns disease, Cx601 is currently awaitingEMA approval and is in phase III trials in the US.

For a late-stage clinical company, TiGenix has a low market cap of191M. Even so, the company seems to be doing well these days with the progress of Cx601 and AlloCSC-01.

If AlloCSC-01 obtains market approval, it could treat the more than 1.9 millionpeople affected by AMI, a major cause of heart failure. So far, most treatments are palliative or restore myocardial function by angioplasty and insertion of a stent to support the vascular lumen.

Stem cell therapy of the heart is definitely not a new topic, but many trials have been conducted using the patients own stem cells derived from the bone marrow. A recent meta-analysisof such trials has suggested that these therapies are safe, but do not enhance cardiac function. TiGenixs approach using allogeneic heart-derived stem cells may offer a new and promisingopportunity in thefield.

On March 8-9 in Boston, stem cell medicine biotechnology start-up Asymmetrex led attendees at the 6th Annual Clinical Trials Supply New England 2017 conference in discussions about the need for quality controls for the supply of tissue stem cells used for treatments in either FDA-approved clinical trials or unregulated private stem cell clinics. Though these two stem cell treatment settings are often contrasted regarding their safety and effectiveness, Asymmetrex stressed that patient care and research progress is compromised in both because of the lack of essential quality control tests for the number and quality of transplanted tissue stem cells.

Boston, MA (PRWEB) March 14, 2017

At the 6th Annual Clinical Trials Supply New England 2017 conference, held in Boston from March 8-9, James Sherley, M.D., Ph.D., director of Asymmetrex, led discussions that evaluated the quality of U.S. supplies of stem cells used in clinical trials compared to private stem cell clinics. Private stem cell clinics have been criticized for not employing research standards that are necessary to establish the therapeutic effectiveness of treatments with statistical confidence. In part because of this difference in practice, they are also often accused of making unproven claims about the effectiveness of their therapies.

Sherley presented comparisons of key operational elements to argue that, given good intent in both settings, the two different settings of stem cell treatments had both distinct and shared shortcomings. He noted, however, that the most significant shortcoming, which stem cell clinical trials and private stem cell clinics share, was perennially overlooked.

Based on the number of reported stem cell clinical trials and private stem cell clinics, Sherley estimated that close to a quarter-million patients in the U.S. now receive stem cell treatments each year. Though many of these occur within FDA-approved clinical trials, their number is dwarfed nearly 10 times by the number of treatments that occur in private stem cell clinics. It shocked the audience of clinical trial suppliers to learn that there was no stem cell quality control test performed for any of these many treatments.

Even for approved stem cell medicine treatments like bone marrow transplantation and umbilical cord blood transplant, there is no stem cell-specific quality control test available. Counts of total cells are made, but these do not adequately predict stem cell number or function. Biomarkers designated for tissue stem cells are also expressed by stem cells' more abundant non-stem cell products. So, the biomarkers lack sufficient specificity to be used to count and monitor tissue stem cell function.

Without a quality control test for tissue stem cell number, stem cell treatments in all settings proceed without knowing the dose of treating tissue stem cells. This previously unavoidable therapeutic blind spot creates an instant treatment risk. It also precludes effective analyses to optimize treatment procedures, to compare different treatments, or to relate treatment outcomes to tissue stem cell dose. Without knowing stem cell dose, the interpretation of any stem cell treatment in terms of stem cells as the responsible agents is compromised.

In this context, Sherley announced briefly to attendees that Asymmetrex's new AlphaSTEM Test for counting adult tissue stem cells and providing data on their viability and tissue cell renewal function represented the needed first quality control test for tissue stem cell treatments, whether in clinical trials, in private stem cell clinics, or approved therapies. In particular, he indicated that both stem cell treatment patients and progress in stem cell medicine would benefit from existing clinical trial supply companies developing into future private stem cell clinic supply companies to insure the quality of stem cell treatment preparations. Sherley said that, of course, their partnership with Asymmetrex to implement its new stem cell-specific quality control test was an all around best solution for accelerating progress in stem cell transplantation medicine.

Vampire facials sound like a totally modern sci-fi development, but people have thought that drinking or slathering on blood can heal and renew for millennia. Pliny the Elder, nearly 2,000 years ago, wrote, [e]pileptic patients are in the habit of drinking the blood even of gladiators, draughts teeming with life. Elizabeth Bthory, a noblewoman from early modern Hungary, was said to have murdered virgins and then bathed in their blood in order to retain her youth. (Its worthwhile to note that King Louis XV and Marie Antoinette were also accused of bathing in their subjects blood.) In the stories, Bthory literally soaks up the youth of virgins via contact with their blood.

We think topically applied and ingested blood, bones, organs, and cells are magical sources of life force, health, and youth that somehow surpass the efficacy of less gory, more common ingredients.

The tales of blood baths seem spurious to say the least, and apparently theyre not backed up by primary evidence. But the fact that people have been passing the stories along for centuries tells us something about how we think. Even now, we seem to really dig the idea of applying or consuming human cells for the purpose of absorbing beauty and health from them. Vampire facelifts and Dr. Barbara Sturms MC1 cream make use of plasma from ones own blood drawn and separated in-office to supposedly renew skin. We think topically applied and ingested blood, bones, organs, and cells are magical sources of life force, health, and youth that somehow surpass the efficacy of less gory, more common ingredients.

Ingredients associated with conception, birth, and nursing seem to particularly excite us. Semen facials inadvisable and groan-worthy seem to make the rounds again when clicks are needed. In Korea, the brand Isa Knox uses recombinant human placenta protein (rHPP-8TM) in the Tervina line, supplied by the CHA Placenta Institute (part of the CHA Global Medical Network that includes a university medical school and institutes for stem cell and cosmetics research).

In the case of human stem cell skincare, companies have slapped a veneer of science on our old magical beliefs to ratchet up prices and expectations.

The idea of human ingredients is so seductive that people pay extra for them even when theyre not actually in the products. A Korean beauty product nicknamed mothers milk, Eureque Muru Mor Cream, contains no human milk, just baby powder fragrance and animal milk extracts that are supposed to be similar to human breast milk. If youre looking for the real deal, check out Mud Facial Bar, which offers an ethically sourced, $10 breast milk add-on for its facials.

In the case of human stem cell skincare, companies have slapped a veneer of science on our old magical beliefs to ratchet up prices and expectations. Stem cells here Im talking about pluripotent human stem cells can be manipulated to become any cell type in the human body under the right conditions and divide essentially without limit to replenish other cells as long as the person or animal is still alive according to the National Institutes of Health.

The twist is that stem cell skincare brands such as Lifeline Skin Care dont actually use whole, live human stem cells in their products. An actual stem cell would need to be kept alive in a skin cream, and that would certainly be challenging to accomplish, according to cosmetic chemist Kelly Dobos. Lifelines parent company, International Stem Cell Corporation, extracts human growth factors from stem cells by stimulating unfertilized eggs. Its the growth factors which stimulate cell growth, differentiation, healing, and proliferation that end up bottled, not the whole stem cells.

There really isn't any concrete, unbiased research to support the use of epidermal growth factors (EGF).

I asked Stephen Alain Ko, cosmetic chemist and blogger at kindofstephen, whether applying growth factors to skin makes sense. He wrote via email, [t]here really isn't any concrete, unbiased research to support the use of epidermal growth factors (EGF) on healthy human skin, and there is also a concern that EGF can also be involved in certain cancer growth as well. Ko noted that Oprah-recommended SkinMedicas TNS Essential Serum ($281 for one ounce) faces a California class action lawsuit claiming the company failed to disclose cancer risks associated with applying human growth factors to skin.

When asked about Skinmedicas TNS Essential Serum, Dobos wrote, [a]t $281 for one ounce and questionable science backing the ingredient claims, I would opt for a less expensive skin care product. Skincare companies dont need to make extravagant claims about the power of stem cell-derived ingredients, or even use whole human stem cells in their products; simply mentioning stem cell taps into long-held beliefs about the power of wearing and consuming human cells and our wallets.
