Shinya Yamanaka: Usually to find a job in the States — from Japan — usually you have to ask your professor in Japan to recommend some place. But unfortunately, at that time, my professor — my mentor in Japan — did not know any labs working on knockout mice. So I did not get any good recommendations. So I had to apply for many positions, which I learned from scientific journals such as Nature and Science. I applied to — I forget — like 20 or 30 different universities and laboratories in the States. And UCSF — University of California at San Francisco — was the first to give me an opportunity. That was why I ended up coming to San Francisco.
