The Center for iPS Cell Research and Application (CiRA) at Kyoto University in Japan is defending Nobel Prize winner Shinya Yamanaka against claims of  image manipulation in multiple studies on which he was an author. The institute says questioning Yamanaka’s integrity without sufficient evidence is “completely unacceptable.”

Yamanaka shared the Nobel Prize in Physiology or Medicine in 2012 and works at CiRA. 

On August 7, Gotham City Research LLC, a short-selling firm based in the United States, released a report alleging image manipulation in several papers by Yamanaka appearing between 2000 and 2020.

An investigation by Kyoto University in Japan has found a researcher guilty of falsifying all but one of the figures in a 2017 stem cell paper.

Yamamizu works at the Center for iPS cell Research and Application (CiRA) at Kyoto University, directed by Shinya Yamanaka, a Nobel Prize winner for his pioneering work in stem cell biology.

A spokesperson for the journal told us that the authors disclosed the problems last week and Stem Cell Reports will be retracting the paper, published last February.

In the university’s official statement, Yamanaka said: Continue reading Researcher at Japan stem cell institute falsified nearly all images in 2017 paper
