Stem cell researcher retracts neuron paper for “image aberrations”

Jens Christian Schwamborn, a stem cell researcher at the University of Luxembourg, is retracting a 2007 paper on how to grow brain cells. The paper, “Ubiquitination of the GTPase Rap1B by the ubiquitin ligase Smurf2 is required for the establishment of neuronal polarity,” was published while Schwamborn was at Westfälische Wilhelms‐Universität Münster in Germany. An anonymous … Continue reading Stem cell researcher retracts neuron paper for “image aberrations”

Stem cell researchers sue Harvard, claiming faulty investigation lost them job offers

Piero Anversa, a stem cell researcher at the Brigham & Women’s Hospital, and a colleague, Annarosa Leri, have sued Harvard over an investigation into their work that they claim has cost them millions in a forfeited sale of their company, and job offers. The team has had a paper in Circulation retracted, and a paper in … Continue reading Stem cell researchers sue Harvard, claiming faulty investigation lost them job offers

Stem cell researcher Hanna “working…to correct the unfortunate and inadvertent mistakes” in papers

Jacob Hanna of Israel’s Weizmann Institute has been a media darling for years, including as a member of the 2010 Technology Review 30 under 35 for his work with stem cells. However, questions have been mounting about his research, both on PubPeer (which has critical comments for 15 papers he’s an author on) and in other stem cell labs, who have … Continue reading Stem cell researcher Hanna “working…to correct the unfortunate and inadvertent mistakes” in papers

Paper on controversial stem cell “stamina therapy” retracted

A Korean stem cell journal has retracted a paper on a controversial Italian treatment that involves harvesting stem cells from bone marrow and injecting them back into the patient. “Stamina therapy” has been pitched as a treatment for everything from Parkinson’s disease to coma, based on a U.S. patent application filed in 2010. The Italian … Continue reading Paper on controversial stem cell “stamina therapy” retracted

Faking data earns stem cell researcher a ban on federal funding

The Office of Research Integrity (ORI) has sanctioned Kaushik Deb, a former post-doc at the University of Missouri-Columbia, who “engaged in misconduct in science by intentionally, knowingly, and recklessly” fabricating data in papers in both Science and Nature (which ultimately rejected his manuscript). Deb was big news in 2007, when Science retracted his paper. Articles … Continue reading Faking data earns stem cell researcher a ban on federal funding

Kidney journal to retract stem cell paper for duplicated and doctored images

Kidney International is in the process of retracting a stem cell paper containing plagiarized images, Retraction Watch has learned. Here’s the notice that will appear for “Human renal stem/progenitor cells repair tubular epithelial cell injury through TLR2-driven inhibin-A and microvesicle-shuttled decorin“:

“Potentially groundbreaking,” “highly provocative:” Nature STAP stem cell peer reviews published

A day after we published the cover letter and peer review reports about the STAP stem cell paper rejected by Science, Science‘s news section has published the same material for the version rejected by Nature. From Science‘s news story about the document:

“Truly extraordinary,” “simply not credible,” “suspiciously sharp:” A STAP stem cell peer review report revealed

Retraction Watch readers are of course familiar with the STAP stem cell saga, which was punctuated by tragedy last month when one of the authors of the two now-retracted papers in Nature committed suicide. In June, Science‘s news section reported: Sources in the scientific community confirm that early versions of the STAP work were rejected … Continue reading “Truly extraordinary,” “simply not credible,” “suspiciously sharp:” A STAP stem cell peer review report revealed
