I think I read somewhere that there had been some research done on using stem cells intravenously with some success for Vascular disease.
But I don't think anyone would seriously think that a bandage laced with stem cells on your foot was going to give you improved blood flow in your upper legs and groin.
In my opinion anyone who looks at the photos and has followed the trial and still can't see how beneficial this could be to hundreds of thousands of people around the world is not worth debating.
And at the end of the day we only need a very small slice of the market to do well.
