Infusing stem cells into the brain may help boost recovery after a stroke, according to a pilot study by Imperial College London.

Scientists believe the cells encourage new blood vessels to grow in damaged areas of the brain.

They found most patients were able to walk and look after themselves independently by the end of the trial, despite having suffered severe strokes.

Larger studies are needed to evaluate whether this could be used more widely.

In this early trial - designed primarily to look at the safety of this approach - researchers harvested stem cells from the bone marrow of five people who had recently had a stroke.

They isolated particular types of stem cells - known as CD34+. These have the ability to stimulate the growth of new blood vessels.

They were infused directly into damaged sections of the brain, via the major artery that supplies this area.

Scientists monitored the patients for six months, charting their ability to carry out everyday activities independently.

Four of the five patients had suffered particularly severe strokes - resulting in the loss of speech and marked paralysis down one side of the body.
