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.

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.

I like the freedom of research. Plus, if I fail in science, I know I can always survive because I have an M.D. This has been my insurance policy.

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

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

I started my career as a surgeon 25 years ago. But it turned out that I am not talented as a surgeon, so I decided to change my career. But I still feel that I am a doctor. So my goal, all my life, is to bring this stem-cell technology to the bedside.

IPS cells can become a powerful tool to develop new drugs to cure intractable diseases because they can be made from patients' somatic cells.

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