"Broad says he is saddened by the Bush Administration's stem-cell ban, which has constrained funding, forced universities to set up redundant labs off-site and let Singapore, Australia and Europe pull ahead of the U.S. in one of the most exciting new fields for fighting disease. "The promise is great," he says."
First off. Nothing is stopping people like Broad from giving as much money as they want to fund it. Just don't expect the 'taxpayer' to do it.
Secondly "The promise is great", but the "results are lacking".
Adult stem cells show much more promise than Embryonic ever will. Unless your goal is to invent a new form of cancer.
If the promise really were great, capitalists and pharmacutical companies would be investing heavily in order to reap billions in profits.
