Whistleblower forces retractions of four stem cell papers amid questions about more than a dozen studies

In a case that is a good reminder of why journal editors shouldn’t ignore anonymous tips, a Seoul National University stem cell researcher has been forced to retract four papers, and withdraw another under peer review, in Antioxidants & Redox Signaling following a whistleblower’s exhaustive analysis. Two retractions by Soo Kyung Kang, a professor of … Continue reading Whistleblower forces retractions of four stem cell papers amid questions about more than a dozen studies

ORI sanctions Oregon eye stem cell researcher for faking data in grant applications

Peter Francis, a former Oregon Health Sciences University (OHSU) eye researcher, has been sanctioned by the U.S. Office of Research Integrity (ORI) for claiming, in grant applications, to have performed experiments that he hadn’t actually done. According to ORI’s case summary, Francis

Journal retracts heart stem cell paper (and pulls no punches) over image fraud

Some retractions beg for a kick of sand in the face, and others do the kicking. Here’s an example of what Charles Atlas might have written had he been a journal editor concerned with research integrity. Experimental Biology and Medicine, the official journal of the Society for Experimental Biology and Medicine, has retracted a 2010 … Continue reading Journal retracts heart stem cell paper (and pulls no punches) over image fraud

Blood retracts stem cell paper from Amy Wagers’ Harvard lab after 14 months of concern

More than 14 months after Blood issued a notice of concern about a paper by a Harvard stem cell scientist and her former post-doc, the journal has retracted the article. Here’s the notice for the paper, “Osteolineage niche cells initiate hematopoietic stem cell mobilization,” by Shane Mayack and Amy Wagers:

In a retraction’s wake: Postdoc Shane Mayack, dismissed from Amy Wagers’ stem cell lab, speaks out

  Last October, Retraction Watch readers will recall, up-and-coming stem cell researcher Amy Wagers retracted a study in Nature describing how her team rejuvenated blood-forming stem cells in older mice. Shane Mayack, a postdoc in Wagers’ lab who had been dismissed after an inquiry into what happened, did not sign that retraction. Since then, Mayack … Continue reading In a retraction’s wake: Postdoc Shane Mayack, dismissed from Amy Wagers’ stem cell lab, speaks out

Another stem cell paper retracted, for “breach of established ethical guidelines”

Last week’s big Retraction Watch news — which got us quoted in the New York Times — was a Nature paper by Amy Wagers and Shane Mayack. The now-retracted paper suggested that the aging of stem cells could be reversed, and Blood has issued a notice of concern about a second paper. Now comes news … Continue reading Another stem cell paper retracted, for “breach of established ethical guidelines”

Highly cited Harvard stem cell scientist retracts Nature paper

Amy Wagers, an up and coming stem cell researcher at Harvard who made a name for herself as a postdoc early by questioning the work of others, has retracted a January 2010 paper she co-authored in Nature. According to the retraction: Three of the authors (J.L.S., F.S.K. and A.J.W.) wish to retract this Article after … Continue reading Highly cited Harvard stem cell scientist retracts Nature paper

Update on stem cell-cancer link retraction: Why not everyone signed, and why authors ended up in another journal first

Last month, we wrote about the retraction of a 2005 paper suggesting that some adult stem cells might give rise to cancer. That, of course, would be a problem if researchers tried treating heart disease and other conditions with them. The paper’s authors retracted it, however, when it became clear that instead of being transformed … Continue reading Update on stem cell-cancer link retraction: Why not everyone signed, and why authors ended up in another journal first

It’s not a tumor: Authors retract 2005 Cancer Research paper linking adult stem cells to cancer

The authors of a 2005 Cancer Research paper that cast some doubt on the safety of a population of adult stem cells used frequently in research have retracted it. According to the retraction, in the August 15 issue of the journal: Upon review of the data published in this article, the authors have been unable … Continue reading It’s not a tumor: Authors retract 2005 Cancer Research paper linking adult stem cells to cancer

Exclusive: Biochemistry journal retracts 25 papers for ‘systematic manipulation’ of peer review

A journal of the UK-based Biochemical Society is retracting 25 papers after finding “systematic manipulation of our peer-review and publication processes by multiple individuals,” according to a statement provided to Retraction Watch.  The batch of retractions for Bioscience Reports is “​​the first time that we have issued this many retractions in one go for articles … Continue reading Exclusive: Biochemistry journal retracts 25 papers for ‘systematic manipulation’ of peer review
