Summary:
Researchers have foud that stimulating a protein on the surface of the brain's stem cells helps rats recover after a stroke. The discovery suggests that in humans it could be possible to provoke the body's own stem cells into repairing an injury, rather than laboriously growing and transplanting new cells.
The researchers believe that many of the body's tissues contain stem cells capable of dividing to make new tissue. But some of these are resistant and do not naturally divide to repair damage wreaked by severe injuries such as stroke or spinal-cord damage.
Commentary: Hopefully this finding can be translated into effective treatments for central nervous system disorders and injuries.
