Jun 8 - Scientists in Britain have developed a way of replacing brain tissue damaged by a stroke, growing stem cells on tiny ping pong ball like structures injected into the brain.
The team wanted to provide a structure for stem cells to cling to while they grow in the brain.
Their system uses tiny particles like ping pong balls, just a tenth of a millimetre across.
Worldwide, stroke accounts for 5.7 million deaths each year and ranks second to heart disease as a cause of death, according to the World Stroke Association.
