Human stem cells protect against acute strokes in rats

Here's the story. Excerpt:

The researchers demonstrated that cells obtained from circulating human blood -- known as human peripheral blood (HPB) cells -- survived without immunosuppression, migrated to the site of stroke injury and significantly improved motor and cognitive performance in transplanted animals....The researchers conclude the preliminary findings support the investigation of HPB cells for neurotransplantation therapy in stroke patients.

Now if they can make this go the other way we're in business.
