Comments on this old interview w/ Mel Gipson regarding Stem Cells therapy experience

Does anybody else has other reports from actuall stem cell therapy outside of clinical trials?
What therapies are available and what do they currently cost?

I found this very promising.

I also believe I've heared Tim Ferris speaking about some stem cell therapy that he had done on himself to heal some old sport injuries. Not sure anymore though.
