Frankly in reading the article posted by someone here on the different types of stem cells, it's very possible the stem cells injected into the knees, etc. are different than the stem cells harvested from the blood. I would like to learn more about that myself.
One thing I believe we're all learning about is that if you begin with the placental cells, you can do almost anything. To me it's a shame the political debate on this throttled development on this in the U.S. I believe that Israel is clearly a world leader in development of technologies that U.S. politicians refuse to allow.
