Stem Cells Help Paralyzed Rats Walk

And they could help humans, too.

("Paralyzed Rats Walk in Stem Cell Study," The Baltimore Sun) -- "A team of Johns Hopkins researchers has restored movement to paralyzed rats using a new method that they say shows the potential of embryonic stem cells to restore function to humans suffering from neurological disorders. 'For the first time we have used stem cells to rewire part of the nervous system,' said Dr. Douglas Kerr, the lead researcher...[Kerr] said the results suggest that embryonic stem cells may one day be used to treat human neurological disorders such as Lou Gehrig's disease, multiple sclerosis and spinal injuries."
