Adult Stem Cells Offer Brain Damage Hope
Tuesday, June 27, 2006 - Stem Cell Guru
The online edition of yesterday's Guardian newspaper, from the UK, carried an article which highlighted research at the US National Institute of Neurological Disorders and Stroke, in Maryland, USA.
In the article 'Stem cells offer brain damage hope', scientists have found a way to make the brain reverse the damage it suffers after a stroke, raising hopes for treatment able to exploit the body's ability to heal itself.
Their experiments used rats whose brains had been starved of oxygen to simulate the effects of a stroke. Strokes kill brain cells and affect the way the body works, with paralysis common.
Researchers stimulated a receptor known as "notch", on the stem cells, and found that it caused reactions that produced new brain cells. Compared with untreated rats, fewer of the rodents that had a stroke and the stem cell therapy were left paralysed.
The technique has wide implications for stem cell research as this work shows a way of using stem cells in the body to promote healing.
