April Flowers for redOrbit.com Your Universe Online Columbia University ophthalmologists and stem cell researchers have developed an experimental treatment for blindness using the patients skin cells, which has improved the vision of blind mice in testing. The findings of this research, published online in the journal Molecular Medicine, suggest that induced pluripotent stem cells (iPS) could soon be used to improve vision in people with macular degeneration and other eye retina diseases. iPS cells are derived from adult human skin cells but have embryonic qualities. With eye diseases, I think were getting close to a scenario where a patients own skin cells are used to replace retina cells destroyed by disease or degeneration, says Stephen Tsang, MD, PhD, associate professor of ophthalmology and pathology & cell biology. Its often said that iPS transplantation will be important in the practice of medicine in some distant future, but our paper suggests the future is almost here. Scientists were very excited by the advent of human iPS cells when they were discovered in 2007, as they provide a way to avoid the ethical complications of embryonic stem cells. Another advantage is that the iPS cells are created from the patients own skin, eliminating … Continue reading →

Dallas, TX (PRWEB) September 30, 2012 Mesenchymal stem cells (MSCs) are multipotent stem cells that can differentiate into a variety of cell types, including osteoblasts, chondrocytes, myocytes, adipocytes, beta-pancreatic islets cells, and even neural cells. MSCs are of intense therapeutic interest because they represent a population of cells with the potential to treat a wide range of acute and degenerative diseases and are immuno-privileged, which makes them an advantageous cell type for allogenic transplantation. In the market research report Mesenchymal Stem Cells Advances & Applications, trend analysis of grant activity, publications, and patent applications reveals that global research activity involving MSCs increased by 112% from 2009 to 2010, and by 116% from 2010 to 2011. This rate accelerated throughout 2011, positioning mesenchymal stem cells as the fastest growing area of stem cell research for 2012. While competitors are guessing, this report divulges exactly where to focus R&D and marketing spend to create the most profitable MSC research products. A key element of this report is survey findings from a large population of mesenchymal stem cell (MSC) researchers that reveals: It is also important for bio-pharmaceutical and pharma companies interested in MSC therapy applications to understand underlying market forces, and in … Continue reading →

SACRAMENTO UC Davis investigators have found new evidence that a promising type of stem cell now being considered for a variety of disease therapies is very similar to the type of cells that give rise to cancer. The findings suggest that although the cells known as induced pluripotent stem cells (iPSCs) show substantial promise as a source of replacement cells and tissues to treat injuries, disease and chronic conditions, scientists and physicians must move cautiously with any clinical use because iPSCs could also cause malignant cancer. The article, "Induced pluripotency and oncogenic transformation are related processes," is now online in the journal Stem Cells and Development. "This is the first study that describes the specific molecular pathways that iPSCs and cancer cells share from a direct comparison" said Paul Knoepfler, associate professor of cell biology and human anatomy, and principal investigator of the study. "It means that much more study is required before iPSCs can be used clinically. However, our study adds to a growing knowledge base that not only will help make stem cell therapies safer, but also provide us with new understandings about the cancer-causing process and more effective ways to fight the disease." Since 2007, cell biologists … Continue reading →

The process researchers use to generate induced pluripotent stem cells (iPSCs)-a special type of stem cell that can be made in the lab from any type of adult cell-is time consuming and inefficient. To speed things up, researchers at Sanford-Burnham Medical Research Institute (Sanford-Burnham) turned to kinase inhibitors. These chemical compounds block the activity of kinases, enzymes responsible for many aspects of cellular communication, survival, and growth. As they outline in a paper published September 25 in Nature Communications, the team found several kinase inhibitors that, when added to starter cells, help generate many more iPSCs than the standard method. This new capability will likely speed up research in many fields, better enabling scientists around the world to study human disease and develop new treatments. "Generating iPSCs depends on the regulation of communication networks within cells," explained Tariq Rana, Ph.D., program director in Sanford-Burnham's Sanford Children's Health Research Center and senior author of the study. "So, when you start manipulating which genes are turned on or off in cells to create pluripotent stem cells, you are probably activating a large number of kinases. Since many of these active kinases are likely inhibiting the conversion to iPSCs, it made sense to … Continue reading →

Public release date: 27-Sep-2012 [ | E-mail | Share ] Contact: Julia Evangelou Strait straitj@wustl.edu 314-286-0141 Washington University School of Medicine Studying leukemia in mice, researchers at Washington University School of Medicine in St. Louis have reduced a life-threatening complication of stem cell transplants, the only curative treatment when leukemia returns. About 50 percent of leukemia patients who receive stem cells from another person develop graft-versus-host disease, a condition where donor immune cells attack the patient's own body. The main organs affected are the skin, liver and gut. Now, the scientists have shown they can redirect donor immune cells away from these vital organs. Steering immune cells away from healthy tissue also leaves more of them available for their intended purpose killing cancer cells. "This is the first example of reducing graft-versus-host disease not by killing the T- cells, but simply by altering how they circulate and traffic," says John F. DiPersio, MD, PhD, the Virginia E. and Sam J. Golman Professor of Medicine. "Donor T-cells do good things in terms of eliminating the recipient's leukemia, but they can also attack normal tissues leading to death in a number of patients. The goal is to minimize graft-versus-host disease, while maintaining … Continue reading →

NOKOMIS, Fla.--(BUSINESS WIRE)-- As Rainbow BioSciences, the biotech subsidiary of Rainbow Coral Corp. (RBCC), works to acquire licensing for commercial use of NASA-developed stem cell expansion technology, the company received good news from a Wall Street analysts forecast on Wednesday. Writing for Seeking Alpha, George Kesarios predicted major growth for the global stem cell market in coming years. Its estimated that the market will be worth about $64 billion by 2015, up from $21.5 billion in 2010. Kesarios attributed the growth largely to a potential revolution in drug companies research and development made possible by an abundance of induced pluripotent stem cells. With these stem cells, scientists can actually create working facsimiles of living human tissue, introduce diseases and observe how they unfold under a microscope, said RBCC CEO Patrick Brown.
