These stem cells can reproduce and be converted into various types of brain cells. To date, only reprogramming in brain cells that were already fully developed or which had only a limited ability to divide was possible. The new reprogramming method presented by the Bonn scientists and submitted for publication in July 2011 now enables derivation of brain stem cells that are still immature and able to undergo practically unlimited division to be extracted from conventional body cells. The results have now been published in the current edition of the prestigious journal Cell Stem Cell.
A new cornea may be the only way to prevent a patient going blind Â– but there is a shortage of donated corneas and the queue for transplantation is long. Scientists at the Sahlgrenska Academy at the University of Gothenburg, Sweden, have for the first time successfully cultivated stem cells on human corneas, which may in the long term remove the need for donators.
For the first time, Massachusetts General Hospital (MGH) researchers have isolated egg-producing stem cells from the ovaries of reproductive age women and shown these cells can produce what appear to be normal egg cells or oocytes. In the March issue of Nature Medicine, the team from the Vincent Center for Reproductive Biology at MGH reports the latest follow-up study to their now-landmark 2004 Nature paper that first suggested female mammals continue producing egg cells into adulthood.
A UCSF stem cell study conducted in mice suggests a novel strategy for treating damaged cardiac tissue in patients following a heart attack. The approach potentially could improve cardiac function, minimize scar size, lead to the development of new blood vessels Â– and avoid the risk of tissue rejection.
In a study to be presented today at the Society for Maternal-Fetal Medicine’s annual meeting, The Pregnancy Meeting Â™, in Dallas, Texas, researchers will report that early transplantation of human placenta-derived mesenchymal stem cells into the lateral ventricles of neonatal rats with birth-related brain damage is possible, and that the donor cells can survive and migrate in the recipient’s brain. The study was designed to have the rat’s brain damage mimic brain injury in infants with very low birth weight.
For the first time ever, stem cells from umbilical cords have been converted into other types of cells, which may eventually lead to new treatment options for spinal cord injuries and multiple sclerosis, among other nervous system diseases.
For years, researchers seeking new therapies for traumatic brain injury have been tantalized by the results of animal experiments with stem cells. In numerous studies, stem cell implantation has substantially improved brain function in experimental animals with brain trauma. But just how these improvements occur has remained a mystery.
Initiated by Lentigen and UH Case Medical Center
Cleveland, OH. and Gaithersburg, MD. Â– University Hospitals (UH) Case Medical Center, Case Western Reserve University School of Medicine and Lentigen Corporation announced today the initiation of a novel Phase I clinical trial of LG631 gene therapy for the protection of hematopoietic stem cells (HSCs) from the dose limiting toxicity of chemotherapy with Temodar.
Researchers from Mount Sinai School of Medicine have discovered the therapeutic benefit of fetal stem cells in helping the maternal heart recover after heart attack or other injury. The research, which marks a significant advancement in cardiac regenerative medicine, was presented today at the American Heart Association’s (AHA) Scientific Sessions 2011 in Orlando, Florida, and is also published in the current issue of Circulation Research, a journal of the AHA.
Durham, NC November 2011 Chinese stem cell scientists have published new research that improves the survival and effectiveness of transplanted stem cells. The research led by Dr Hsiao Chang Chan, from the Chinese University of Hong Kong, is published in Stem Cells.
