Stem Cells Mend Spinal Injuries

Darkman, Walkin Dude writes "New research shows that rats that had their spinal columns severed were able to regain use of their hind legs through the use of stem cells from embryonic rats." From the Wired article: "Spinal cord injuries can be caused by accidents or infections and affect 250,000 people a year in the United States alone, costing $4 billion annually, according to the National Institute of Neurological Disorders. Whittemore's team took specific cells from rat embryos called glial restricted precursor cells -- a kind of stem cell or master cell that gives rise to nerve cells."
