Anecdotal evidence...

Have been waiting for a surge of analytical brilliance to attach to this story of the woman who regained her ability to walk after stem cell treatment. But really, it's just one case, and thus it's hard to conclude much, other than that the Reeve foundation must be over the moon. There's not much data given on her improvement, and she's got more braces and metalwork holding her up than muscle. But it's also hard to ignore that she had been paralyzed for two decades and is now moving.
