Authors “in shock” when image reuse doesn’t fly with publishers of paper on emu oil and stem cells

A team of researchers in Iran has lost a 2018 paper on using emu oil to prepare stem cells because they tried to recycle previously published images. The journal told us that a whistleblower had raised concerns about the article, prompting an involved back-and-forth with the authors and even efforts at accommodation before the eventual … Continue reading Authors “in shock” when image reuse doesn’t fly with publishers of paper on emu oil and stem cells

Stem cell researchers have papers retracted for image manipulation

A group of dentistry researchers in Japan, whose work on stem cells has been the subject of an institutional investigation, have now lost two papers in PLOS ONE for image problems.  The authors, from Aichi Gakuin University in Nagoya, were led by Makio Mogi, a medicinal biochemist at the school. Mogi asked for at least … Continue reading Stem cell researchers have papers retracted for image manipulation

Drip, drip: Former Harvard stem cell researcher up to 18 retractions

Piero Anversa, a former star researcher at Harvard Medical School who left the institution under a cloud, is up to 18 retractions. But that’s barely half of the 31 papers by Anversa’s group that Harvard has requested journals pull over concerns about the integrity of the findings.  The two articles, published in the Proceedings of … Continue reading Drip, drip: Former Harvard stem cell researcher up to 18 retractions

Japanese stem cell fraud leads to a new retraction

Last March, we reported on the retraction of a 2017 paper in Stem Cell Reports by Kohei Yamamizu and colleagues for widespread fabrication of figures. Turns out the problems were at least five years older than that. Yamamizu had received a pink slip from his institution, the Center for iPS Cell Research and Application (CiRA), … Continue reading Japanese stem cell fraud leads to a new retraction

Yesterday, Circulation retracted three papers, and Circulation Research retracted 10. All 13 were … Continue reading Anversa cardiac stem cell lab earns 13 retractions

Journals stamp expressions of concern on 15 papers from Anversa’s cardiac stem cell lab
