Summary:
WASHINGTON (CNN) -- Paralyzed rats were able to move their hind legs in a study in which scientists injected the rodents with stem cells from mouse embryos, according to researchers at Johns Hopkins University.
The scientists said they combined the transplanted stem cells with a "cocktail" of chemicals to help the paralyzed rats regenerate some of their nerve cells, allowing a message from the brain to travel to the spinal cord and then to the legs of the paralyzed rats. Scientists outside the university agreed that the findings were a big step forward in embryonic stem cell research.
