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.

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 thought, we can’t keep destroying embryos for our research. There must be another way.

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

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.
