Stem cell therapy is pretty cool. I remember there were a few young horses from one consigner at Fasig a couple years ago who came with a card informing the buyer of stored umbilical cord blood from the horses' birth as a embryonic stem cell bank.

As an aside, last year I went to the human "stem cell research" clinical ortho at University of Kentucky, but alas, they were not yet in a position to help my torn meniscus. Dara Torres, the Olympic swimmer, had to go overseas to get stem cell treatment on her knee. That result is pending.
Go Lava Man! Glad he's back.
