Study finds blood cells can be reprogrammed to act as embryonic stem cells
In a recent study, U.S. researchers have reprogrammed cells found in circulating blood into cells that are molecularly and functionally indistinguishable from embryonic stem cells, a revolutionary achievement that provides a readily accessible source of stem cells and an alternative to harvesting embryonic stem cells. The findings were prepublished online in Blood, the official journal of the American Society of Hematology.
Lab-grown nerves promote nerve regeneration after injury
Researchers at the University of Pennsylvania School of Medicine have engineered transplantable living nerve tissue that encourages and guides regeneration in an animal model. Results were published this month in Tissue Engineering.
Researchers make stem cell breakthrough
In a study to be released on March 1, 2009, Mount Sinai Hospital's Dr. Andras Nagy discovered a new method of creating stem cells that could lead to possible cures for devastating diseases including spinal cord injury, macular degeneration, diabetes and Parkinson's disease. The study, to be published by Nature online, accelerates stem cell technology and provides a road map for new clinical approaches to regenerative medicine.
