STEM CELL RESEARCH IN PROGRESS TO EXPLORE MORE AND TO CONQUER DISEASE New Stem Cell Technique for Leukemia Treatment: British scientists have developed a new stem cell technique that could help patients with advanced leukemia or lymphoma. They genetically tinkered with donor stem cells -- master cells that can develop into virtually any cell type -- so that they can survive highly toxic chemotherapy. Trial of High-Risk Therapy for Severe MS Planned LONDON (Reuters Health) - Scientists announced plans on Monday for a major trial of a controversial stem cell therapy in people with severe multiple sclerosis (MS) who do not respond to conventional treatment. The therapy involves removing and storing the patients'''' own stem cells from bone marrow, then using drugs to knock out the immune system in order to stabilize the course of MS. The stem cells are transplanted back into the body to reconstitute the lost blood cells. Patients have very few infection-fighting white blood cells for the first 10 days and have to stay in an extremely clean environment until the stem cell therapy takes a hold. Stem Cells Used to Treat Brain Cancer in Mice : LOS ANGELES (Reuters) - Injecting neural stem cells engineered to produce a cancer-killing protein into mice with brain cancer extends the animals'''' survival and even immunizes a third of them against the cancer, researchers said on Monday. "Malignant brain tumors are highly invasive. The main tumor mass often spawns outgrowth...this is a way to target cancer cells that migrate away from the primary brain tumor," said Dr. Moneeb Ehtesham, an author of the study conducted at Cedars-Sinai Medical Center in Los Angeles. Stem Cell Science Offers New Hope to Diabetics: LOS ANGELES (Reuters) - Type 1 diabetes patients may be able to avoid the need for daily insulin shots through transplants of insulin-producing stem cells, but the procedure faces some hurdles including finding the cells and dealing with immune-system rejection, researchers said. Researchers have sought for decades to prove that islet cell transplantation could be a cure for Type 1 diabetes, said Taylor Mayo, a spokesman for the City of Hope Cancer Center in Duarte, California, one of 10 research centers chosen by the US National Institutes of Health (news - web sites) to conduct studies aimed at duplicating on a larger scale the islet cell transplantation done in Canada.
Hopes Raised of Using Stem Cells For Treating Muscular Dystrophy A rare natural experiment has given researchers hope of using stem cells to treat muscular dystrophy, a group of genetic diseases that cause progressive wasting of the muscles. Umbilical Stem Cells Show Promise : SEATTLE Scientists said Tuesday they can increase the number of stem cells derived from umbilical cord blood significantly by exposing the blood to a particular molecule. The finding could have important implications for stem cell research. Dr. Irwin Bernstein, a pediatric oncologist at Fred Hutchinson Cancer Center and the University of Washington, in Seattle, led a research team to determine how best to use stem cells that can be derived from umbilical cord blood. Stem Cells Offer Hope to Heart Attack Victims LONDON (Reuters) - Stem cells may help patients recover from heart attacks by triggering new cell growth in damaged tissue, scientists said on Friday. Stem cells are so-called master cells that can develop into various tissues in the body and using them to repair damaged hearts is a hot area of medical research. Two teams of doctors from Germany and Hong Kong reported promising results after transplanting stem cells extracted from bone marrow into heart muscle, although they said more research was needed on the procedure. The aim of the procedure is to stimulate blood vessel growth in areas without sufficient blood supply, a process known as angiogenesis. It could eve
