Adult stem cells didn’t work until they were tried. Embryonic stem cells have just had their first human clinical trial approved. Of course they haven’t helped yet.
The problem is that they haven't been that successful in earlier trials on animals. It will be interesting to see how they do in human clinical trials.
The best thing about adult stem cells is that they can be taken from other parts of the patient's own body, precluding the need for a lifetime of taking anti-rejection drugs
Wait, you’re saying that it’s cutting edge news that the new embryos created at Harvard or California from solicited oocytes and sperm?
Singapore has been throwing money hand over fist at embryonic stem cell research. That wasn’t enough? Are you saying that $3 Billion in California, $250 million in Houston, all that money at Harvard, South Korea, the UK, were just not enough additional funding and opportunities over and above the millions the NIH has allocated for the currently approved embryonic stem cell lines?
Well, perhaps if all the money spent so far can’t show us nearly the results that adult stem cell has — much less the hoped for successes from iPSC’s — perhaps we don’t need to throw good money after bad.
