Kyoto University Detects Misconduct in iPS Cell-Related Paper (News)


Kyoto, Jan. 22 (Jiji Press)—Kyoto University said Monday data falsification has been detected in an iPS cell-related research paper.

In the paper published online by the US scientific journal Stem Cell Reports in February last year, Yamamizu Kōhei, a specially appointed assistant professor at the university's Center for iPS Cell Research and Application, and colleagues claimed they generated in vitro the blood-brain barrier using human induced pluripotent stem cells.

But it has been found that all six main figures in the article as well as five of six supplementary figures were manipulated, the university announced.

The university plans to punish not only Yamamizu, 36, but Yamanaka Shin'ya, professor at the university and chief of the center. Yamanaka won the 2012 Nobel Prize in Physiology or Medicine for creating iPS cells, which can develop into almost all tissues.

"As head of the center, I feel deep remorse," Yamanaka told a press conference held by the university. He said resignation from the post would be one of possible punitive measures against himself.
