Stem cells found in umbilical cord blood.

Scientists at the University of Minnesota recently observed that, the transplanted stem cells found in human umbilical cord blood, took on properties of brain cells and seemed to spur the rats’ brains to “rewire” themselves and eventually reverse the effects of stroke in lab rats.

The researchers almost fully healed the rats 48 hours after the animals sustained brain damage. Typically doctors need to act within three hours to treat a human stroke patient successfully.

Now scientists are finding that stem cells from umbilical cord blood - once thought capable only of turning into blood cells—may really be able to grow into other kinds of cells as well.Link [news.nationalgeographic.com/news/2006/04/0406_060406_cord_blood.html]
