Two Moriguchi stem cell papers being retracted

It was, as Nature News wrote last month, a story that “seemed too good to be true:” Stem-cell transplant claims debunked Transplant of induced pluripotent stem cells to treat heart failure probably never happened Hisashi Moriguchi, a visiting researcher at the University of Tokyo, had claimed a result that would have put him years ahead … Continue reading Two Moriguchi stem cell papers being retracted

Pulp fiction: doubtful “veracity” leads to retraction of endodontics paper

This one’s like taking candy from a baby. The Journal of Endodontics — or JOE — has retracted a 2011 article (its online date) on the prospects of tissue engineering for the mouth by a group of Chinese authors who appear to have tried to pass bogus data into print. The paper was titled “Mineralized … Continue reading Pulp fiction: doubtful “veracity” leads to retraction of endodontics paper

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

Updated: Slate retracts story on Glenn McGee and Celltex following lawsuit threats, as McGee resigns from company

Slate has retracted a story about controversial bioethicist Glenn McGee and his involvement with Celltex Therapeutics, a Texas-based company that says it extracts and banks stem cells from people’s fat. Where the story by University of Minnesota bioethicist Carl Elliott once appeared now sits this editor’s note:

Mysterious retraction in the Journal of Biological Chemistry for Takashi Tsuji’s group

The authors of a paper in the Journal of Biological Chemistry (JBC) have retracted it, but don’t ask us why. This being the JBC, the retraction notice for “Human T-cell Leukemia Virus Type I Tax Down-regulates the Expression of Phosphatidylinositol 3,4,5-Trisphosphate Inositol Phosphatases via the NF-κB Pathway” is the very definition of opaque:

A mega-correction, but no retraction, in the Journal of Cell Science

In our 2011 year-end post, we promised to keep …an eye on what may be an emerging trend: The mega-correction. We’ve seen errata notices that correct so many different errors, it’s hard to believe the paper shouldn’t have been retracted. It’s unclear what this means yet, but watch this space for coverage of more examples. … Continue reading A mega-correction, but no retraction, in the Journal of Cell Science

Second retraction arrives in Alirio Melendez case

Alirio Melendez, whose former employer, the National University of Singapore, is investigating about 70 of his papers, has retracted a second study. Here’s the notice for the 2010 Journal of Molecular Cell Biology paper, “Sphingosine-1-phosphate mediates proliferation maintaining the multipotency of human Adult Bone Marrow and Adipose Tissue-derived Stem Cells:”

“Ill communication” leads to retraction of tissue paper (sorry) for authorship issues

Like many researchers, Frank Walboomers frequently checks the scientific databases to see when his latest publications appear. He was doing so a few months ago when he came across his name on an article — “Effects of pro-inflammatory cytokines on mineralization potential of rat dental pulp stem cells” — published online in July in the … Continue reading “Ill communication” leads to retraction of tissue paper (sorry) for authorship issues

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
