Stem Cell cure for disc degeneration

[Crystal33]

Has anyone done any research or aware of any expert opinions on whether this company's stem cell "cure" for disc degenaration is the real deal.
It works in sheep and about to be tested in humans... see link.

I was thinking that stem cell treatment may not work where disc degeneration is caused by decrease in nutrient supply as happens in aging humans, rather than by injection of a chemical to degenerate healthy discs as was done in the sheep test. The sheep discs would have good nutrient supply and therefore be able to remain healthy after being restored by stem cells.
