Stem cell transplant restores memory, learning in mice

For the first time, human embryonic stem cells have been transformed into nerve cells that helped mice regain the ability to learn and remember.

A study at UW–Madison is the first to show that human stem cells can successfully implant themselves in the brain and then heal neurological deficits, says senior author Su-Chun Zhang, a professor of neuroscience and neurology.

Long considered to be little more than putty in the brain and spinal cord, the star-shaped astrocyte has found new respect among neuroscientists who have begun to recognize its many functions in the brain, not to mention its role in a range of disorders of the central nervous system.

UW-Madison scientist and brainiac Su-Chun Zhang has raised the stakes — and astonished the world — by proving it’s possible to grow the healthy brain cells that could one day repair damage caused by everything from strokes to disease to spinal cord injuries. When UW wins the race to cure chronic diseases, he and James Thomson will be crossing the finish line together.”
