Well, they have an exhibit here. Riken too, but they will probably only show regenerative medicine for non-hair related issues.
Interested in this too. I have been searching the Internet trying to find out how. I guess we would have to sign up to a Japanese clinical trials recruitment program and tell them that we specifically want to be guinea pigs for Tsuji. The only question is, which registrar will Riken/Organ Tech. use?
