This article tells about a woman who is walking, years after a spinal cord injury, after therapy using umbilical cord stem cells.
If this pans out to be more than a one-time thing, it's bloody wonderful. I've read that fetal stem cells have not really worked out well, but umbilical cells are a different matter. They seem to work much better, and don't involve the ethical problems with fetal cells.
I hope this works out.
