On Umbilical Cord Blood

The National Geographic looks at research into the stem cells found in umbilical cord blood: scientists "recently announced that they were able to largely reverse the effects of stroke in lab rats using stem cells found in human umbilical cord blood. In the experiment, conducted by neurologist Walter Low and his colleagues, the transplanted stem cells took on properties of brain cells and seemed to spur the rats' brains to "rewire" themselves. 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. Cord-blood cell transplants are already becoming common as a therapy for diseases of the blood. Now scientists like Low are finding that stem cells from umbilical cord blood - once thought capable only of turning into blood cells - may be able to grow into other kinds of cells as well."
