New Scientist reports that a small trial involving three partially paralyzed patients saw injections of 20 million neural stem cells administered directly into their spinal cords. The stem cells were harvested from donated fetal brain tissue, and the patients received immunosuppressive drugs to minimize the risks of rejection.
Before treatment, all of the patients could feel nothing below their nipples. Six months on, two of them can now feel touch and heat as far down as their belly button.
