Quadriplegic treated with stem cells regains some motor function

Keck Medical Center of USC announced that a team of doctors became the first in California to inject an experimental treatment made from stem cells, AST-OPC1, into the damaged cervical spine of a recently paralyzed 21-year-old man as part of a multi-center clinical trial...

Two weeks after surgery, Kris began to show signs of improvement. Three months later, he's able to feed himself, use his cell phone, write his name, operate a motorized wheelchair and hug his friends and family.
Improved sensation and movement in both arms and hands also makes it easier for Kris to care for himself, and to envision a life lived more independently. 

"As of 90 days post-treatment, Kris has gained significant improvement in his motor function, up to two spinal cord levels," said Dr. Liu.  "In Kris' case, two spinal cord levels means the difference between using your hands to brush your teeth, operate a computer or do other things you wouldn't otherwise be able to do, so having this level of functional independence cannot be overstated."
