Summary:
WASHINGTON – Scientists have used embryonic stem cells to restore function in the legs of paralyzed rats, raising hopes they may some day achieve the same result in humans. Researchers extracted the cells from rat embryos, then used chemicals to coax them into becoming motor neurons, cells that carry impulses from the brain and spinal cord to receptors in the muscles. The neurons were transplanted into the rats, allowing three in every four animals to bear weight on their hind legs and take steps after six months.
