There is no way now to get around some use of embryos. But my goal is to avoid using them.
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.
IPS cells can become a powerful tool to develop new drugs to cure intractable diseases because they can be made from patients' somatic cells.
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.
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.
