ScienceDaily (May 21, 2012) A substance in human mesenchymal stem cells that promotes growth appears to spur restoration of nerves and their function in rodent models of multiple sclerosis (MS), researchers at Case Western Reserve University School of Medicine have found. In animals injected with hepatocyte growth factor, inflammation declined and neural cells grew. Perhaps most important, the myelin sheath, which protects nerves and their ability to gather and send information, regrew, covering lesions caused by the disease. "The importance of this work is we think we've identified the driver of the recovery," said Robert H. Miller, professor of neurosciences at the School of Medicine and vice president for research at Case Western Reserve University. Miller, neurosciences instructor Lianhua Bai and biology professor Arnold I. Caplan, designed the study. They worked with Project Manager Anne DeChant, and research assistants Jordan Hecker, Janet Kranso and Anita Zaremba, from the School of Medicine; and Donald P. Lennon, a research assistant from the university's Skeletal Research Center. In MS, the immune system attacks myelin, risking injury to exposed nerves' intricate wiring. When damaged, nerve signals can be interrupted, causing loss of balance and coordination, cognitive ability and other functions. Over time, intermittent losses … Continue reading →

Osiris Therapeutics Inc says Canadian health regulators have approved its treatment for acute graft-versus host disease in children, making it the first stem cell drug to be approved for a systemic disease anywhere in the world. Osiris shares rose 14 percent to $6.00 in extended trading after the news was announced. Graft versus host disease (GvHD) is a potentially deadly complication from a bone marrow transplant, when newly implanted cells attack the patient's body. Symptoms range from abdominal pain and skin rash to hair loss, hepatitis, lung and digestive tract disorders, jaundice and vomiting. The disease kills up to 80 percent of children affected, Osiris said. To date there have been no approved treatments for the disease. Canadian authorities approved the therapy, Prochymal, for use in children who have failed to respond to steroids. Prochymal was approved with the condition that Osiris carry out further testing after it reaches the market. C. Randal Mills, the company's chief executive, said in an interview that could take three to four years. Some investment analysts have been skeptical about Prochymal's future. In 2009, two late-stage clinical trials failed to show the drug was more effective overall than a placebo in treating the disease, … Continue reading →

Thirty Percent of Patients Show Improved Functioning after Stem Cell Therapy Philadelphia, Pa. (May 17, 2012) One of the first long-term studies of stem cell treatment for spinal cord injury shows significant functional and other improvements in three out of ten patients, reports a study in the May issue of Neurosurgery, official journal of the Congress of Neurological Surgeons. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health. The results support the safety of mesenchymal stem cells (MSCs) derived from the patient's own bone marrow, showing "continuous and gradual motor improvement" in at least some patients with disability caused by spinal cord injury. The lead author of the new study was Dr. Sang Ryong Jeon of University of Ulsan College of Medicine, Seoul, South Korea. Evidence of Improved Function after MSC Treatment for Spinal Cord Injury The researchers performed MSC transplantation in ten patients with permanent motor (movement) deficits or paralysis (paraplegia or quadriplegia) after spinal cord injury. Mesenchymal stem cells are a type of "multipotent" cell that can be cultured from adult bone marrow and induced to develop into many different types of cells. The cultured MSCs were injected directly into the injured … Continue reading →

By Meg Tirrell - 2012-05-18T20:13:19Z Osiris Therapeutics Inc. (OSIR) rose after the company said it won the worlds first approval for a stem- cell drug, gaining clearance in Canada to sell Prochymal for a disease that can attack patients who received bone-marrow transplants. Osiris climbed 5.5 percent to $5.55 at 4 p.m. New York time. The shares have lost 24 percent in the last 12 months. Prochymal was approved for the treatment of acute graft versus host disease in children for whom steroids havent worked, the Columbia, Maryland-based company said yesterday in a statement. Steroids have a 30 percent to 50 percent success rate, and severe GvHD can be fatal in 80 percent of cases, according to the company. The therapy uses mesenchymal stem cells derived from bone marrow that can take on different forms to combat the immune reaction that causes patients to literally peel out of their skin and shed their intestinal lining, Osiris Chief Executive Officer Randal Mills said in a telephone interview. The disease has no equal. The company hasnt sought approval for this indication in the U.S., where regulators asked for more data before considering whether to allow sales of the drug, Mills said. Prochymal … Continue reading →

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 … Continue reading →
