It is five years since our medical scientist training program (MSTP) of the University of Tokyo started. The program is now working well, thanks to the former head Shigeo Okabe, lecturer Kano Mitsunobu (currently a professor at Okayama University), Assistant Professor Makoto Kurachi (currently a post-doc at University of Pennsylvania). Since last year, new stuffs were recruited and involved in managing the MSTP. Here, I think it is a good chance to verbalize the policy and history of the MSTP.
