There is no way now to get around some use of embryos. But my goal is to avoid using them.

Patients' lives are more important than embryos. I do want to avoid the use of embryos if possible.

When I saw the embryo, I suddenly realized there was such a small difference between it and my daughters. I thought, we can't keep destroying embryos for our research. There must be another way.

My goals over the decade include to develop new drugs to treat intractable diseases by using iPS cell technology and to conduct clinical trials using it on a few patients with Parkinson's diseases, diabetes or blood diseases.

I grew so depressed from the lack of support that I considered quitting. No one understood me.

Researchers should always consider ethical concerns on scientific research and disclose their data to the public. Scientists also need to discuss issues surrounding their research with those who are concerned.
