By Stem Cell Treatment

MONTRAL, April 30, 2012 /CNW/ - Canada's most coveted stem cell prize will be awarded to a Stem Cell Network researcher who has used drug screening to find a potential new treatment for a deadly form of cancer.

Dr. Aaron Schimmer, associate professor in the University of Toronto's Department of Medical Biophysics and a clinician-scientist in the Princess Margaret Cancer Program/Ontario Cancer Institute at University Health Network, has received the 2012 Till & McCulloch Award, presented each year by the Stem Cell Network in recognition of the year's most influential peer-reviewed article by a researcher in Canada. Dr. Schimmer will accept the award and present a lecture entitled "Novel therapeutic strategies to target leukemia stem cells" as part of the Till and McCulloch Meetings in Montral at 2 p.m. this afternoon.

In an advance interview, Dr. Schimmer described his findings and their potential as a new drug therapy in the treatment of leukemia.

"When you treat patients with leukemia, you can kill off 99 per cent of their leukemic cells with just about anything, and yet, 80 per cent or more of patients relapse," Schimmer explained. "When we examined this in a really objective way, the question was not how to kill off those bulk cells - we already knew how to do that - but are we really missing a critical component of what we should be targeting?"

Dr. Schimmer and his team eventually found that cutting off the energy production capacity of bulk leukemia cells and leukemia stem cells was a way of treating the disease, and that the compound tigecyclinean FDA-approved antibiotic sometimes used to treat skin and abdominal infectionswas up to the task.

"Tigecycline appeared to work by essentially shutting down the energy supply of the leukemia cells and stem cells," said Dr. Schimmer. "Essentially it is like producing a selective power outage in leukemia cells but not normal cells."

By focusing on FDA-approved drugs, Dr. Schimmer was able to produce results that were quickly translated into clinical trials. Less than two years passed between his initial findings and the commencement of a phase-one clinical triala process that can otherwise take three or four times that long.

"It is incredibly impressive how much progress Dr. Schimmer has made in such a short period of time by using these stem cell screening techniques," said Stem Cell Network Scientific Director Michael Rudnicki. "By identifying drugs which are already approved for human therapies and testing their efficacy in treating diseases such as leukemia, Dr. Schimmer has shaved years off of the clinical trial process. It is likely that his discovery will improve the outcomes for many patients in the near future."

In 2005, the Stem Cell Network established the Till & McCulloch Award in honour of Canadians Drs. James Till and Ernest McCulloch, whose pioneering work established the field of stem cell research. The Award had been granted at the Stem Cell Network's Annual Scientific Meeting, but became part of the Till & McCulloch Meetings this year.

The previous winner was Timothy Caulfield, who was recognized for his global leadership in the field of stem cell ethics.

A Bellevue doctor is one of only two researchers in the country testing stem cells as an anti-aging treatment.

Working with volunteer patients, Dr. Fredric Stern extracts stem cells with a liposuction-like procedure. The cells are then mixed with a special medium.

"Half is saved cyrogenically for future use and the other half is shipped to the laboratory in Arizona where on that end the stem cells are grown further," Stern said.

The end product goes into a cream called tropoelastin. The hope is that high concentrations of a patient's own stem cells in the cream will boost the skink's ability to repair itself.

If the eye cream proves successful in the eight-week study, the company will also offer a facial cream. Both could be available within a few months.

Stern said he expects the price to be comparable to high-end cosmetic products that typically cost hundreds of dollars.

Stern said the skin treatment is just the beginning. He said wound care is another possible use.

Division of Labor in Neural Stem Cell Maintenance

By Stem Cell Medical Center

Newswise NEWARK, N.J. -- Sibling growth factors cooperate to maintain a pool of neuron-generating stem cells in the brain, according to a study published in the journal Stem Cells by researchers at the University of Medicine and Dentistry of New Jersey (UMDNJ).

Numerous soluble proteins and receptors help to maintain neural stem cells (NSCs) supportive environment in central nervous system (CNS). NSCs access some of these nurturing factors by sending cellular extensions into the cerebral spinal fluid (CSF), which is rich in stem cell-promoting proteins.

Insulin-like growth factors (IGF-I and IGF-II) are essential for the growth and development of the CNS. But although they are abundant in the brain and CSF, it was not clear whether they are required by NSCs. Steven Levison, PhD, and Teresa Wood, PhD, of UMDNJ-New Jersey Medical School and colleagues now show that IGF-I and II cooperate to maintain NSC numbers and the NSCs ability to self-renew. IGF-I maintains NSC numbers by promoting cell division (via the IGF-I receptor), whereas IGF-II drives the expression of proteins essential for NSC self-renewal and stemness (via the insulin receptor).

The role of IGF-I and -II in maintaining NSC numbers and function might help to explain the cognitive impairments associated with aging, as the abundance of both proteins declines with age.

Disclosure: This study was funded by a Deans grant from UMDNJ-New Jersey Medical School, NIH grants (R21HL094905, F31NS065607 and T32-HL069752) and a grant from the LeDucq Foundation.

The University of Medicine and Dentistry of New Jersey (UMDNJ) is New Jerseys only health sciences university with more than 6,000 students on five campuses attending the state's three medical schools, its only dental school, a graduate school of biomedical sciences, a school of health related professions, a school of nursing and New Jerseys only school of public health. UMDNJ operates University Hospital, a Level I Trauma Center in Newark, and University Behavioral HealthCare, which provides a continuum of healthcare services with multiple locations throughout the state.

Medical Center Researchers Discover "Housekeeping" Mechanism for Brain Stem Cells

By Stem Cell Medical Center

Published: April 22, 2012

Findings offer new insights into neurologic development and regenerative therapies for neurologic disease

(New York, NY, April 22, 2012) Researchers at Columbia University Medical Center (CUMC) have identified a molecular pathway that controls the retention and release of the brains stem cells. The discovery offers new insights into normal and abnormal neurologic development and could eventually lead to regenerative therapies for neurologic disease and injury. The findings, from a collaborative effort of the laboratories of Drs. Anna Lasorella and Antonio Iavarone, were published today in the online edition of Nature Cell Biology.

The research builds on recent studies, which showed that stem cells reside in specialized niches, or microenvironments, that support and maintain them.

From this research, we knew that when stem cells detach from their niche, they lose their identity as stem cells and begin to differentiate into specific cell types, said co-senior author Antonio Iavarone, MD, professor of Pathology and Neurology at CUMC.

However, the pathways that regulate the interaction of stem cells with their niche were obscure, said co-senior author Anna Lasorella, MD, associate professor of Pathology and Pediatrics at CUMC and a member of the Columbia Stem Cell Initiative.

In the brain, the stem cell niche is located in an area adjacent to the ventricles, the fluid-filled spaces within the brain. Neural stem cells (NSCs) within the niche are carefully regulated, so that enough cells are released to populate specific brain areas, while a sufficient supply is kept in reserve.

In previous studies, Drs. Iavarone and Lasorella focused on molecules called Id (inhibitor of differentiation) proteins, which regulate various stem cell properties. They undertook the present study to determine how Id proteins maintain stem cell identity.

BioTime’s Subsidiary Cell Cure Neurosciences, Ltd. Provides Update on OpRegen® Product Development

By Uncategorized

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

BioTime, Inc. (NYSE Amex: BTX) announced today that Charles S. Irving, Ph.D., the CEO of BioTimes subsidiary Cell Cure Neurosciences, Ltd. will provide an update on the development of OpRegen at an investor meeting in New York City. In his presentation, Dr. Irving will describe the unmet medical needs and markets for the treatment of the dry form of age-related macular degeneration (AMD), and the advantages of Cell Cures OpRegen which has been produced from human embryonic stem cells in culture conditions free of animal products, eliminating the need for designating the product as a xenotransplantation therapeutic. Dr. Irving will also discuss Cell Cures collaboration with Teva Pharmaceutical Industries Ltd., under which Teva has the option to develop and commercialize both OpRegen and OpRegen-Plus. Dr. Irving will describe the nature of the ongoing preclinical studies which are expected to lead to regulatory filings for the initiation of human clinical trials in 2013. Dr. Irvings presentation will be available on BioTimes web site http://www.biotimeinc.com as well as Cell Cure Neurosciences web site at http://www.cellcureneurosciences.com.

Background.

Age-related macular degeneration is the leading cause of blindness in an aging population. It is widely believed that the loss or dysfunction of a particular type of cell called retinal pigment epithelial (RPE) cells is the root cause of the disease. While therapies exist to treat what is called the wet form of macular degeneration exist, there are no therapies for the dry form. The transplantation of healthy RPE cells may provide a superior treatment for this devastating disorder. Cell Cures OpRegen is xeno-free, meaning that no animal products were used in the culture of the human embryonic stem cell-derived RPE cells. The use animal products to culture cells often results in the designation of the therapy as a xenotransplantation product, even though the cells themselves are of human origin. Xenotransplantation may raise purity issues, increasing the costs of product development along with other risks and uncertainties. The production of animal product-free OpRegen will therefore eliminate concerns of xenotransplantation and may provide cost savings in development and production should the product successfully complete clinical trials and be approved for human use.
