Does the Director of the National Institutes of Health not know the difference between embryonic and adult stem cells? Or is he just biased?

In an interview with the New England Journal of Medicine, Francis Collins talks about the number of "stem cell" clinical trials:

Steinbrook: What will the results of stem-cell research mean for human health?

Collins: My crystal ball is just as cloudy as everyone elses. However, the developments in understanding stem cells and how they could potentially be brought to bear for a whole host of medical problems are some of the more exciting things that have happened in the last decade. In terms of therapeutics, we are just so early on. The one clinical trial approved by the Food and Drug Administration - for spinal cord injury - is currently on hold.

What?!? The "one clinical trial" Collins refers to is the one embryonic stem cell experiment with patients that is out there. And it is indeed on hold.

But there are at least 2,000 clinical trials for Adult Stem Cells (this search term doesn't capture them all).

By the way, there are quite a few done on the NIH campus itself.

Remember, it's the National Institutes of Health...
