The University of Tokyo today rejected the researcher who claimed to have achieved what would have been the first world trial the treatment of human patients with cells created from their own induced pluripotent stem (iPS). The researcher Hisashi Moriguchi, later admitted at a press conference that the initial application of the injection of cardiac muscle cells derived from iPS cells into the hearts of five patients was false, but maintained the procedure was performed on one patient at a Boston hospital in mid-2011.
"On October 19, the University of Tokyo has initiated a disciplinary dismissal Hisashi Moriguchi, a project scientist at the university hospital," reads a press release sent by e-mail reporters and posted this afternoon Japan time. He explained that the school's use of work rules call termination "in the case of severe damage to the honor or credibility of the university."
"It was conduct unbecoming a member of the faculty of this university, and he was treated strictly" wrote Fumio Isoda, executive vice president, in a statement accompanying. He added that the incident was regrettable and said an ongoing investigation would "clarify the facts as soon as possible."
Although investigations are ongoing, the scale and nature of the problem is becoming clearer. Moriguchi was the corresponding author of two papers online Exchange Protocol Nature Group website, ovarian tissue cryopreservation and cover another direct reprogramming describing human liver cancer cells using chemicals. Both contributions initially made several co-authors, but notes on the Exchange Protocol website indicate that as of Wednesday, all co-authors had requested that their names be removed. One of those, Taro Okitsu school Keio University of Medicine in Tokyo, said exchange protocol that has not participated in the study, according to the online edition of the English language The Yomiuri daily .
Another co-author on the Exchange protocol contributions Chifumi Sato, who studies liver diseases and health promotion at Tokyo Medical and Dental University (TMDU) could also face disciplinary action . The Commission of Inquiry concluded that TMDU Sato knew that his name was used on Moriguchi papers even though he did not check the data, according to comments made to the press by Ikuo Morita, a university trustee oversees research. "This behavior is inappropriate for a researcher," the Asahi Shimbun Article online quoted Morita as saying after a Thursday night committee meeting.
