The National Academy of Sciences guidelines for stem cell research prohibits payment to egg donors, and scientists in the U.S. have embraced those principles. There is a right way and a wrong way, and we must be sure to perform this vitally important medical research the right way.

We scientists typically are good at doing our research, but we're not so good at communicating it to the public -- its relevance and why we should spend taxpayer dollars to fund it.

California could become the global center for stem cell research with that kind of investment and the talent that's there. But within Harvard alone, we have as many outstanding scientists as arguably all of California. I think many of us are envious of the resources in California, but we're doing our best to organize and effort around somewhat more modest funding.

a huge chance to do pioneering high-risk research.

It has been discovered that one of our scientists has fabricated data for use in scientific research. The results ... are based on false facts. This is very serious.

I am confident with the scientists we have we can do this research in an ethical and moral way. It would be huge. There would no place better to do this than Michigan.
