Tampa, Fla. (June 4, 2012) When autologous (self-donated) lung-derived mensenchymal stem cells (LMSCs) were transplanted endoscopically into 13 adult female sheep modeled with emphysema, post-transplant evaluation showed evidence of tissue regeneration with increased blood perfusion and extra cellular matrix content. Researchers concluded that their approach could represent a practical alternative to conventional stem cell-based therapy for treating emphysema.

The study is published in Cell Transplantation (21:1), now freely available on-line at http://www.ingentaconnect.com/content/cog/ct/.

"Mensenchymal stem cells are considered for transplantation because they are readily available, highly proliferative and display multi-lineage potential," said study corresponding author Dr. Edward P. Ingenito of the Brigham and Women's Hospital Division of Pulmonary and Critical Care Medicine. "Although MSCs have been isolated from various adult tissues - including fat, liver and lung tissues - cells derived from bone marrow (BM) have therapeutic utility and may be useful in treating advanced lung diseases, such as emphysema."

However, according to the authors, previous transplantation studies, many of which used an intravenous delivery method, have shown that BM-MSCs have been only marginally successful in treating lung diseases. Further, therapeutic responses in those studies have been limited to animal models of inflammatory lung diseases, such as asthma and acute lung injury.

To try and answer the questions surrounding the utility of BM-MSCs for treating advanced emphysema, a disease characterized by tissue destruction and loss of lung structural integrity, for this study the researchers isolated highly proliferative, mensenchymal cells from adult lung parenchyma (functional tissue) (LMSCs) and used an endoscopic delivery system coupled with a scaffold comprised of natural extracellular matrix components.

"LMSCs display efficient retention in the lung when delivered endobronchially and have regenerative capacity through expression of basement membrane proteins and growth factors," explained Dr. Ingenito.

However, despite the use of autologous cells, only a fraction of the LMSCs delivered to the lungs alveolar compartment appeared to engraft. Cell death likely occurred because of the failure of LMSCs to home to and bind within their niche, perhaps because the niche was modified by inflammation or fibrosis. These cells are attachment-dependent and failure to attach results in cell death."

Their findings did suggest, however, that LMSCs were capable of contributing to lung remodeling leading to documented functional improvement rather than scarring 28 days post transplantation.

MADISON Breast-cancer researchers at the University of Wisconsin-Madison have found that two related receptors in a robust signaling pathway must work together as a team to maintain normal activity in mammary stem cells.

Mammary stem cells produce various kinds of breast cell types. They may also drive the development and growth of malignant breast tumors.

Published recently in the Journal of Biological Chemistry, the research also suggests that a new signaling pathway may be involved, a development that eventually could take cancer-drug manufacturers in a new direction.

"We wanted to know if we could use this knowledge to inform us about what might be the transition that occurs to start tumor growth and maintain it," says senior author Dr. Caroline Alexander, professor of oncology at the McArdle Laboratory for Cancer Research at the School of Medicine and Public Health.

The paper describes new information about the Wnt signaling pathway. Wnt signaling underlies numerous activities in normal development, but when the system is unregulated, cancer often occurs.

"Wnt signaling is very important for both stem cells and tumor growth. We need to know the details of the signaling process so that we can use the positive aspects of Wnt signaling for regenerative medicine, and eliminate the negative cancer-causing aspects," says Alexander, a member of the UW Carbone Cancer Center (CCC).

Regenerative biologists typically add Wnt proteins together with other agents to guide the differentiation of lung, bone and heart stem cells, she notes.

The UW researchers zeroed in on two related Wnt receptors on the cell surface--LRP5 and LRP6. The receptors normally respond to Wnt ligands that approach cells to initiate a signaling cascade inside.

ORANGE, Calif.--(BUSINESS WIRE)--

A CHOC Childrens research project, under the direction of Philip H. Schwartz, Ph.D., senior scientist at the CHOC Childrens Research Institute and managing director of the facilitys National Human Neural Stem Cell Resource, has been awarded a $5.5 million grant from the California Institute for Regenerative Medicine (CIRM). The grant will be used to develop a stem cell-based therapy for the treatment of mucopolysaccharidosis (MPS I), a fatal metabolic disease that causes neurodegeneration, as well as defects in other major organ systems.

Based on a number of medical and experimental observations, children with inherited degenerative diseases of the brain are expected to be among the first to benefit from novel approaches based on stem cell therapy (SCT).

Dr. Schwartz explains, While uncommon, pediatric genetic neurodegenerative diseases account for a large burden of mortality and morbidity in young children. Hematopoietic (bone marrow) stem cell transplant (HSCT) can improve some non-neural symptoms of these diseases, but does not treat the deadly neurodegenerative process. Our approach targeting the effects of the disease on organs besides the brain with HSCT and neurodegeneration with a second stem cell therapy specifically designed to treat the brain is a strategy for whole-body treatment of MPS I. Our approach is also designed to avoid the need for immunosuppressive drugs to prevent rejection of the transplanted cells.

This research is designed to lead to experimental therapy, based on stem cells, by addressing two critical issues: early intervention is required and possible in this patient population; and teaching the immune system not to reject the transplanted cells is required. This research also sets the stage for efficient translation of this technology into clinical practice, by adapting transplant techniques that are standard in clinical practice or in clinical trials, and using laboratory cell biology methods that are easily transferrable to clinical cell manufacturing.

Nationally recognized for his work in the stem cell field, Dr. Schwartz research focuses on the use of stem cells to understand the neurobiological causes of autism and other neurodevelopmental disorders.

Named one of the best childrens hospitals by U.S. News & World Report (2011-2012) and a 2011 Leapfrog Top Hospital, CHOC Children's is exclusively committed to the health and well-being of children through clinical expertise, advocacy, outreach and research that brings advanced treatment to pediatric patients.

Five scientists from the University of California, San Diego and its School of Medicine have been awarded almost $12 million in new grants from the California Institute for Regenerative Medicine (CIRM) to conduct stem cell-based research into regenerating spinal cord injuries, repairing gene mutations that cause amyotrophic lateral sclerosis and finding new drugs to treat heart failure and Alzheimer's disease.

The awards mark the third round of funding in CIRM's Early Translational Awards program, which supports projects that are in the initial stages of identifying drugs or cell types that could become disease therapies. More than $69 million in awards were announced yesterday, including funding for first-ever collaboratively funded research projects with China and the federal government of Australia.

"With these new awards, the agency now has 52 projects in 33 diseases at varying stages of working toward clinical trials," said Jonathan Thomas, JD, PhD and CIRM governing board chair. "Californians should take pride in being at the center of this worldwide research leading toward new cures. These projects represent the best of California stem cell science and the best international experts who, together, will bring new therapies for patients."

The five new UC San Diego awards are:

With a $1.8 million award, Lawrence Goldstein, PhD, professor in the Department of Cellular and Molecular Medicine, Howard Hughes Medical Institute Investigator and director of the UC San Diego Stem Cell Program, and colleagues will continue their work developing new methods to find and test drug candidates for Alzheimer's disease (AD). Currently, there is no effective treatment for AD. The researchers screen novel candidates using purified human brain cells made from human reprogrammed stem cells. Already, they have discovered that these human brain cells exhibit a unique biochemical behavior that indicates early development of AD in a dish.

Mark H. Tuszynski, MD, PhD, professor of neurosciences and director of the Center for Neural Repair at UC San Diego, and colleagues seek to develop more potent stem cell-based treatments for spinal cord injuries. By combining grafts of neural stem cells with scaffolds placed at injury sites, the researchers have reported substantial progress in restoring functional improvement in impaired animal models. The new $4.6 million grant will fund work to identify the optimal human neural stem cells for preclinical development and, in an unprecedented step, test this treatment in appropriate preclinical models of spinal cord injury, providing the strongest validation for human translation.

Amyotrophic lateral sclerosis or ALS (Lou Gehrig's disease) is a progressive neurological condition that is currently incurable. Gene Yeo, PhD, assistant professor in the Department of Cellular and Molecular Medicine, and colleagues will use a $1.6 million grant to exploit recent discoveries that specific mutations in RNA-binding proteins cause neuronal dysfunction and death. They will use neurons generated from patient cells containing the mutations to identify the unique RNA "signature" of these doomed neurons and screen for drug-like compounds that bypass the mutations to correct the RNA signature to obtain healthy neurons.

Eric David Adler, MD, an associate clinical professor of medicine and cardiologist, studies heart failure, including the use of stem cells to treat it. His $1.7 million award will fund research into Danon disease, a type of inherited heart failure that frequently kills patients by their 20s. Adler and colleagues will turn stem cells created from skin cells of patients with Danon disease into heart cells, then screen hundreds of thousands of drug candidates for beneficial effects. The most promising drugs will subsequently be tested on mice with a genetic defect similar to Danon disease, with the ultimate goal of identifying a suitable candidate for human clinical trials. The research may have broader applications for other conditions with similar pathogenesis, such as cancer and Parkinson's disease.

UC San Diego researchers receive new CIRM funding

Five UC San Diego scientists have received almost $12 million combined from the California Institute for Regenerative Medicine to pay for stem cell-based research, the university announced today.

A team led by Lawrence Goldstein, of the Department of Cellular and Molecular Medicine and director of the UC San Diego Stem Cell Program, was given $1.8 million to continue looking for new methods to find and test possible medications for Alzheimer's disease, according to UCSD. They use reprogrammed stem cells in their work.

Dr. Mark Tuszynski, professor of neurosciences and director of the Center for Neural Repair, received $4.6 million to develop more potent stem cell-based treatments for spinal cord injuries.

Gene Yeo, assistant professor in the Department of Cellular and Molecular Medicine, was awarded $1.6 million to continue research into treatments for amyotrophic lateral sclerosis. His research hopes to take advantage of recent discoveries about ALS, or Lou Gehrig's disease, which center on mutations in RNA-binding proteins that cause dysfunction and death in neurons.

Dr. Eric David Adler, an associate clinical professor of medicine and cardiologist, was granted $1.7 million to screen potential drugs for Danon disease, a type of inherited heart failure that frequently kills patients by their 20s.

Yang Xu, a professor in the Division of Biological Sciences, was given $1.8 million to research the use of human embryonic stem cells to produce a renewable source of heart muscle cells that replace cells damaged or destroyed by disease, while overcoming biological resistance to new cells.

"With these new awards, the (institute) now has 52 projects in 33 diseases at varying stages of working toward clinical trials,'' said Jonathan Thomas, chairman of the CIRM governing board. "Californians should take pride in being at the center of this worldwide research leading toward new cures.''

CIRM was established in November 2004 with voter passage of the California Stem Cell Research and Cures Act. UC San Diego has received $112 million since CIRM began providing grants six years ago.

UC San Diego Scientists Net $12 Million For Stem Cell Research

DUARTE, Calif.--(BUSINESS WIRE)--

City of Hope was granted a $5,217,004 early translational research award by the California Institute for Regenerative Medicine (CIRM) to support the development of a T cell-based immunotherapy that re-directs a patients own immune response against glioma stem cells. City of Hope has been awarded more than $49.7 million in grant support from CIRM since awards were first announced in 2006.

City of Hope is a pioneer in T cell immunotherapy research, helping to develop genetically modified T cells as a treatment for cancer. This strategy, termed adoptive T cell therapy, focuses on redirecting a patients immune system to specifically target tumor cells, and has the potential to become a promising new approach for treatment of cancer.

In this research, we are genetically engineering a central memory T cell that targets proteins expressed by glioma stem cells, said Stephen J. Forman, M.D., Francis and Kathleen McNamara Distinguished Chair in Hematology and Hematopoietic Cell Transplantation and director of the T Cell Immunotherapy Research Laboratory. Central memory T cells have the potential to establish a persistent, lifelong immunity to help prevent brain tumors from recurring.

The American Cancer Society estimates that more than 22,000 people in the U.S. will be diagnosed with a brain tumor this year, and 13,700 will die from the disease. Glioma is a type of brain tumor that is often difficult to treat and is prone to recurrence. Currently, less than 20 percent of patients with malignant gliomas are living five years after their diagnosis. This poor prognosis is largely due to the persistence of tumor-initiating cancer stem cells, a population of malignant cells similar to normal stem cells in that they are able to reproduce themselves indefinitely. These glioma stem cells are highly resistant to chemotherapy and radiation treatments, making them capable of re-establishing new tumors.

Researchers at City of Hope previously have identified several proteins as potential prime targets for the development of cancer immunotherapies, such as interleukin 13 receptor alpha 2, a receptor found on the surface of glioma cells, and CD19, a protein that is active in lymphoma and leukemia cells. Both investigational therapies are currently in phase I clinical trials. Forman is the principal investigator for the newly granted study which will develop a T cell that targets different proteins expressed by glioma stem cells. Christine Brown, Ph.D., associate research professor, serves as co-principal investigator, and Michael Barish, Ph.D., chair of the Department of Neurosciences, and Behnam Badie, M.D., director of the Brain Tumor Program, serve as co-investigators on the project.

Because cancer stem cells are heterogeneous, our proposed therapy will target multiple antigens to cast as wide a net as possible over this malignant stem cell population, said Brown.

While in this effort, we are targeting a neurological cancer, our approach will lead to future studies targeting other cancers, including those that metastasize to the brain, added Barish.

The CIRM grant will help us to build a targeted T cell therapy against glioma that can offer lasting protection, determine the best way to deliver the treatment, establish an efficient process to manufacture these T cells for treatment, and get approval for a human clinical trial, said Badie.

City of Hope is also a collaborative partner providing process development, stem cell-derived cell products and regulatory affairs support in two other CIRM-funded projects that received early translational research grants. Larry Couture, Ph.D., senior vice president of City of Hopes Sylvia R. & Isador A. Deutch Center for Applied Technology Development and director of the Center for Biomedicine & Genetics, is working with Stanford University and Childrens Hospital of Orange County Research Institute on their respective projects.

IT'S current preservation for future regeneration - and now umbilical cord tissue is going on ice in Australia for the first time.

Usually discarded after birth, umbilical tissue from newborn babies is being collected and cryogenically frozen to be used one day for regenerative and stem cell medicine. And it doesn't just have potential for the babies involved, either. Experts say stem cells could also be used for family members who are genetically compatible.

It is hoped the cells will eventually be able to be used to repair damaged tissues and organs, with researchers investigating its uses for treating diseases like multiple sclerosis, cerebral palsy and diabetes, as well as for bone and cartilage repair.

Although cord blood storage has been available for many years, Cell Care Australia has added cord tissue storage in anticipation of new discoveries in the regenerative medicine field.

Cell Care Australia medical director associate professor Mark Kirkland said the storage process - already popular in the US, Europe and Southeast Asia - was long overdue for Australian shores.

"The science is developing around the world and we're really behind the rest of the world in providing parents the option to store these cells and we thought it was about time it was brought here," he said.

"It's finding a way to take what would otherwise be waste tissue and turning it into something of potential future value for not only your child but also potentially for other family members.'

Parramatta couple Tim and Padma Vellaichamy are among the first to use the service in Australia.

Mr Vellaichamy, 31, said he heard of the technology while working as a dentist in India and decided to store their daughter's cord cell tissue after birth three weeks ago.

SOUTH SAN FRANCISCO, CA--(Marketwire -05/14/12)- VistaGen Therapeutics, Inc. (OTC.BB: VSTA) (VSTA.OB), a biotechnology company applying stem cell technology for drug rescue, today issued the following letter to its stockholders and the investment community from its CEO, Shawn Singh.

To our valued Stockholders:

Since becoming a public company one year ago, we have progressed to perhaps the most exciting time in our company's 14-year history. To arrive at this point, more than $45 million, obtained through various strategic collaborations, investments and grant awards, has been carefully employed. We believe our pluripotent stem cell technology platform, Human Clinical Trials in a Test Tube, combined with the network of strategic relationships we have announced, will allow us to secure additional capital and the large market drug rescue opportunities that can deliver value to our stockholders.

Since the beginning of the year, our team has carefully reviewed our Top 10 drug rescue opportunities and narrowed our focus to our Top 5 candidates. Now we intend to launch our initial drug rescue program and secure strategic capital necessary to support it, as well as launch our second drug rescue program by year-end. We also are working on validation of LiverSafe 3D, our bioassay system for drug rescue involving liver toxicity and drug metabolism issues, for launch during the first half of next year.

The pharmaceutical industry continues to face extremely high barriers in bringing new medicine to market. The number of drugs approved by the FDA over the past decade has dropped precipitously, by over 50%, in spite of staggering increases in resources devoted to R&D by pharmaceutical companies. Based on the progress we have made with CardioSafe 3D and our efforts to build our strategic drug rescue ecosystem of collaborators, we believe our core business model -- to use our stem cell technology and strategic relationships to develop less toxic variants of drugs that have already been proven in vitro to be effective -- is now more commercially promising than at any other point in our history. We believe we will be able to help major pharmaceutical companies avoid the loss of years of time and millions of dollars spent in developing new therapies that have positive efficacy data, but must be discontinued due to later discovery of unsafe toxicity levels for human heart and liver tissue.

Over the past year, we have secured additional intellectual property protection and entered into strategic relationships with leading biotech firms and academic researchers to support development of our stem technology and our drug rescue-based commercialization initiatives:

Over the next 12 months, we have an ambitious agenda to work closely with our advisors and collaborators to secure capital and achieve these transformative milestones:

Our goals are reachable, with strategic financing. We believe we have the right technology, intellectual property, development teams and specialized focus to deliver on our founding mission -- "putting humans first" -- bringing clinically relevant human biology to the front end of the drug development process, long before standard animal and human testing, and using better cells to make better medicine.

We would like to thank our partners, advisors, employees and each of you, our loyal stockholders, for helping support us in our efforts to deliver long-term value for you.

Sincerely,

DUBLIN--(BUSINESS WIRE)--

Research and Markets (http://www.researchandmarkets.com/research/lffnp7/stem_cell_research) has announced the addition of the "Stem Cell Research Products: Opportunities, Tools & Technologies 2012 (Updated)" report to their offering.

Stem cells are primitive cells found in all multi-cellular organisms that are characterized by self-renewal and the capacity to differentiate into any mature cell type. Several broad categories of stem cells exist, including embryonic stem cells, derived from blastocysts; fetal stem cells, obtained from aborted fetuses; adult stem cells, found in adult tissues; cord blood stem cells, isolated from umbilical tissue; dental stem cells, derived from deciduous teeth; cancer stem cells, which give rise to clonal populations of cells that form tumors or disperse in the body; and animal stem cells, derived from non-human sources.

In a developing embryo, stem cells can differentiate into all of the specialized embryonic tissues. In adult organisms, stem and progenitor cells act as a repair system for the body, replenishing specialized cells. Of interest to researchers is the potential for use of stem cells in regenerative medicine to treat conditions ranging from diabetes, to cardiovascular disease and neurological disorders. Additionally, the ability to use stem cells to improve drug target validation and toxicology screening is of intense interest to pharmaceutical companies. Stem cells are also being studied for their ability to improve both the understanding and treatment of birth disorders.

To facilitate research resulting from interest in these far-ranging applications, a large and growing stem cells research products market has emerged. Large companies selling stem cell research products include Life Technologies, BD Biosciences, Thermo Fisher Scientific, and Millipore, although dozens of other suppliers exist as well. Products offered by these companies include: antibodies to stem cell antigens, bead-based stem cell separation systems, stem cell protein purification and analysis tools, tools for DNA and RNA-based characterization of stem cells, stem cell culture and media reagents, stem cell specific growth factors and cytokines, tools for stem cell gene regulation, a range of stem cell services, tools for in vivo and in vitro stem cell tracking, and stem cell lines.

Dr. Julio C. Voltarelli, who made a significant impact in cell transplantation, dies at 63

Distinguished Brazilian professor pioneered bone marrow transplantation

Newswise Tampa, Fla. (May. 9th , 2012) Julio C. Voltarelli, MD, PhD, professor at the Ribeiro Preto School of Medicine at the University of So Paulo, Brazil, died March 21, 2012 at the age of 63. Dr. Voltarelli, who was on the editorial board of the Cell Transplantation journal, published by Cognizant Communication Corporation, and an important factor in the journals success, was a distinguished stem cell researcher and head of the bone marrow transplantation unit at the Ribeiro Preto School of Medicine.

Dr. Voltarelli had a significant impact on Brazilian stem cell transplantation science, said Dr. Maria C. O. Rodrigues, Dr. Voltarellis longtime colleague. He was driven to bring the benefits of the newest cellular therapies to those with ALS, MS and type 1 diabetes. His efforts and dedication will be greatly missed.

Dr. Voltarelli, a graduate of the Ribeiro Preto School of Medicine, served post-doctoral fellowships at the University of California San Francisco, the Fred Hutchinson Cancer Research Center in Seattle, and the Scripps Research Institute in San Diego. He returned to Brazil in 1992 and started a highly ranked bone marrow transplantation program at the Ribeiro Preto School of Medicine. In 2002, Dr. Voltarelli initiated the schools research efforts in stem cell transplantation for autoimmune diseases, later focusing on diabetes, graft-versus-host disease and sickle cell anemia.

At the time of his death, Dr. Voltarelli, in addition to serving as head of the bone marrow transplantation unit, also served as research coordinator for the Center for Cellular Therapy at the So Paulo Research Foundation and the National Institute of Science and Technology in Stem Cells and Cell Therapy. He was recently elected president of the Brazilian Society of Bone Marrow Transplantation.

Julio C. Voltarelli, Pioneer in Cell Transplantation, Dies at 63

ScienceDaily (May 10, 2012) This summer's action film, "The Amazing Spider-Man," is another match-up between the superhero and his nemesis the Lizard. Moviegoers and comic book fans alike will recall that the villain, AKA Dr. Curt Connors, was a surgeon who, after losing an arm, experimented with cell generation and reptilian DNA and was eventually able to grow back his missing limb.

The latest issue of the journal Physiology contains a review article that looks at possible routes that unlock cellular regeneration in general, and the principles by which hair and feathers regenerate themselves in particular.

The authors apply what is currently known about regenerative biology to the emerging field of regenerative medicine, which is being transformed from fantasy to reality.

Review Article

While the concept of regenerative medicine is relatively new, animals are well known to remake their hair and feathers regularly by normal regenerative physiological processes. In their review, the authors focus on (1) how extrafollicular environments can regulate hair and feather stem cell activities and (2) how different configurations of stem cells can shape organ forms in different body regions to fulfill changing physiological needs.

The review outlines previous research on the role of normal regeneration of hair and feathers throughout the lifespan of various birds and mammals. The researchers include what is currently known about the mechanism behind this re-growth, as well as what gaps still exist in the knowledge base and remain ripe for future research.

The review examines dozens of papers on normal "physiological regeneration" -- the re-growth that happens over the course of an animal's life and not in response to an injury. This regeneration takes place to accommodate different stages in an animal's life (e.g., replacing downy chick feathers with an adult chicken's, or replacing the fine facial hair of a young boy with the budding beard of an adolescent), or in response to various environmental conditions (e.g., cats shedding a thick winter coat in the summer heat but re-growing it when the seasons change again, or snowshoe hares switching from brown in the summer to white in the winter for camouflage).

These changes seem to respond both to internal cues such as physiology of the hair follicle itself, or external cues such as the environment, but the mechanisms behind these normal alterations are largely unknown. Stem cells inside the follicle prompt hair and feather regeneration, but researchers are still unsure how to guide those cells to form the shape, size, and orientation of these "skin appendages" so that controlled re-growth is possible. Additionally, scientists are still unsure how to re-grow hair on skin in people after severe injuries that lead to scar tissue.

Importance of the Findings

The reviewed studies suggest that while researchers are making headway in understanding how and why hair and feathers regenerate after normal loss or in response to different life stages, much still remains unknown. This missing knowledge could hold valuable clues to learning how to regenerate much more complicated and valuable structures after loss to injury, such as fingers and toes.

A new study by researchers at the University of California, Los Angeles (UCLA) has discovered two adult stem cell-like subpopulations in adult human skin.

The findings allow for further research to be done in the area of personalized medicine and patient-specific cellular therapies.

The study, using technology from Fibrocell Science, allowed the researchers to identify and confirm two types of cells in human skin cell cultures; the possible source of stem cell-like subpopulations from skin biopsies would be faster to perform, painless, and less invasive than current extractions from adipose tissues and bone marrow.

The research, featured in the inaugural issue of BioResearch Open Access, discusses two subtypes of cells. BioResearch Open Access is a bimonthly, peer-reviewed journal. It features scientific topics like biochemistry, bioengineering, gene therapy, genetics, microbiology, neuroscience, regenerative medicine, stem cells, systems biology, tissue engineering and biomaterials, and virology.

Being able to identify two sub-populations of rare, viable and functional cells that behave like stem cells from within the skin is an important finding because both cell types have the potential to be investigated for diverse clinical applications, commented Dr. James A. Bryne, lead author of the report.

Brynes research, first at Stanford University then at UCLA, focused on reprogramming beginnings of cells from animals and then humans. A graduate of Cambridge University, Bryne studied the intra- and inter-species of epigenetic reprogramming. His work also highlighted how primate embryonic stem cells could be derived from somatic cell nuclear transfers.

The study published in BioResearch Open Access confirmed previous research that identified a rare population of cells in adult human skin that had a marker called stage-specific embryonic antigen 3 (SSEA3). Bryne and his colleagues found that there was an increase in the amount of SSEA3 expressing cells after injury to the human skin. It showed that the SSEA3 biomarker could be used to help identify and isolate cells with tissue-regenerative traits.

Finding these rare adult stem cell-like subpopulations in human skin is an exciting discovery and provides the first step towards purifying and expanding these cells to clinically relevant numbers for application to a variety of potential personalized cellular therapies for osteoarthritis, bone loss, injury and/or damage to human skin as well as many other diseases, remarked Bryne, an Assistant Professor of Molecular and Medical Pharmacology at the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA.

Bryne and his team used Fibrocell technology to collect cells from skin samples, cultured the cells in the lab, and purified them by fluorescence-activated cell sorting (FACS). The FACS tagged suspended cells with fluorescent markers for undifferentiated stem cells. The researchers were able to separate the rare cell subpopulations from other kinds of cells.

CINCINNATI Researchers have rejuvenated aged hematopoietic stem cells to be functionally younger, offering intriguing clues into how medicine might one day fend off some of the ailments of old age.

Scientists at Cincinnati Children's Hospital Medical Center and the Ulm University Medicine in Germany report their findings online May 3 in the journal Cell Stem Cell. The paper brings new perspective to what has been a life science controversy countering what used to be broad consensus that the aging of hematopoietic stem cells (HSCs) was locked in by nature and not reversible by therapeutic intervention.

HSCs are stem cells that originate in the bone marrow and generate all of the body's red and white blood cells and platelets. They are an essential support mechanism of blood cells and the immune system. As humans and other species age, HSCs become more numerous but less effective at regenerating blood cells and immune cells. This makes older people more susceptible to infections and disease, including leukemia.

Researchers in the current study determined a protein that regulates cell signaling Cdc42 also controls a molecular process that causes HSCs from mice to age. Pharmacologic inhibition of Cdc42 reversed HSC aging and restored function similar to that of younger stem cells, explained Hartmut Geiger, PhD, the study's principal investigator and a researcher in the Division of Experimental Hematology/Cancer Biology at Cincinnati Children's, and the Department of Dermatology and Allergic Diseases, Ulm University Medicine.

"Aging is interesting, in part because we still don't understand how we age," Geiger said. "Our findings suggest a novel and important role for Cdc42 and identify its activity as a target for ameliorating natural HSC aging. We know the aging of HSCs reduces in part the response of the immune system response in older people, which contributes to diseases such as anemia, and may be the cause of tissue attrition in certain systems of the body."

The findings are early and involve laboratory manipulation of mouse cells, so it remains to be seen what direct application they may have for humans. Still, the study expands what is known about the basic molecular and cellular mechanisms of aging a necessary step to one day designing rational approaches to aiding a healthy aging process.

One reason the research team focused on Cdc42 is that previous studies have reported elevated activity of the protein in various tissue types of older mice which have a natural life span of around two years. Also, elevated expression of Cdc42 has been found in immune system white blood cells in older humans.

In the current study, researchers found elevated activity of Cdc42 in the HSCs of older mice. They also were able to induce premature aging of HSCs in mice by genetically increasing Cdc42 activity in the cells. The aged cells lost structural organization and polarity, resulting in improper placement and spacing of components inside the cells. This disorganization contributed to the cells' decreased functional efficiency.

MARLBOROUGH, Mass.--(BUSINESS WIRE)--

Advanced Cell Technology, Inc. (ACT; OTCBB: ACTC), a leader in the field of regenerative medicine, announced today that Massachusetts Eye and Ear (Mass. Eye and Ear) has received institutional review board (IRB) approval to be a site for the companys Phase I/II clinical trial for dry age-related macular degeneration (dry AMD), using human embryonic stem cell (hESC)-derived retinal pigment epithelial (RPE) cells.

We are delighted to announce that Mass. Eye and Ear will participate as a site for our clinical trial for dry AMD, said Gary Rabin, ACTs chairman and CEO. Dr. Dean Eliott and his team are deeply committed to finding new treatments for preventing blindness, and we very much look forward to tapping into his expertise and insight into the progression of macular degenerative disorders. The primary teaching hospital for ophthalmology at Harvard Medical School, Mass. Eye and Ear is ranked as among the top ophthalmology hospitals in the country by U.S. News & World Report and has a reputation that is unrivaled.

The Phase I/II trial is a prospective, open-label study designed to determine the safety and tolerability of the hESC-derived RPE cells following sub-retinal transplantation into patients with dry AMD. The trial will ultimately enroll 12 patients, with cohorts of three patients each in an ascending dosage format.

Dry AMD represents one of the largest unmet medical needs in ophthalmology, commented Dr. Dean Eliott, M.D. a full time retina surgeon, scientist and Associate Director of the Retina Service at Mass. Eye and Ear. We appreciate the opportunity to get some first-hand experience with the protocol and be involved with the international team that has been assembled around the U.S. and European trials.

Founded in 1824, the Massachusetts Eye and Ear Infirmary is an independent specialty hospital affiliated with Harvard Medical School.

Further information about patient eligibility for the dry AMD study is available at http://www.clinicaltrials.gov; ClinicalTrials.gov Identifier: NCT01344993.

About dry AMD Degenerative diseases of the retina are among the most common causes of untreatable blindness in the world. Age-related macular degeneration (AMD) is the leading cause of blindness in people over age 60 in the United States, and the vast majority of cases of AMD are of the dry form, which is currently untreatable.

About hESC-derived RPE Cells The retinal pigment epithelium (RPE) is a highly specialized tissue located between the choroid and the neural retina. RPE cells support, protect and provide nutrition for the light-sensitive photoreceptors. Human embryonic stem cells differentiate into any cell type, including RPE cells, and have a similar expression of RPE-specific genes compared to human RPE cells and demonstrate the full transition from the hESC state.
