Don't be so quick to discount stem cell treatments. Up to now, it may not be helpful for paralysis but just you wait a few years.

I know a woman who has undergone radiation for bone cancer - then her own stem cells were removed and treated and reinjected. The healthy cells began growing immediately.

For the time being at least, due to a low immunity, she has to be especially careful of bacterial contamination. We can't visit her, hug her, or shake her hand.

Not discounting anything. What I wonder, though, is why we seem to have stem cells available for repairs but the body seems not to have any mechanism to move them on-site to do the repairs.

Could a viral infection have inhibited a normal process?
