Caught Our Notice: Oops — paper included proofreader’s query

Title: Concise Review: Mesenchymal Stem Cells in Neurodegenerative Diseases

What Caught Our Attention: Everyone makes mistakes — but some are more amusing than others. In one recent correction, the publisher (Wiley) admitted to including a proofreader’s query in the published manuscript. But didn’t say what the query was.

We looked around, and think we found the added notes in the abstract on the PubMed entry (emphasis ours):  Read the rest of this entry »

JCI retracts paper by stem cell biologist Jacob Hanna, citing “figure irregularities”

with 9 comments

jciapril2015The Journal of Clinical Investigation has retracted a 2004 paper by Jacob Hanna, a highly cited stem cell researcher in Israel whose work has been dogged by questions about its validity.

Questions about the work, and other articles on which Hanna was an author, were raised on PubPeer last November. This is his first retraction.

The retraction stems from “a number of figure irregularities;” the authors say they were “inadvertently introduced,” and subsequent work has supported their data and conclusions. However, due to the “number of serious mistakes,” the JCI editorial board chose to retract the article. Hanna and corresponding author Ofer Mandelboim at The Lautenberg Center for General and Tumor Immunology — part of Hebrew University, in Jerusalem, where Hanna used to work — say they have accepted the decision.

Hanna, currently at the Weizmann Institute of Science, studies ways to reprogram cells to become more versatile stem cells. He also spent time as a postdoc at the Whitehead Institute in Cambridge and Mount Sinai, in New York City.

Six of Hanna’s papers have been cited more than 500 times, according to Thomson Scientific’s Web of Knowledge. The most-cited, with more than 1,000 citations, was a 2008 Nature paper.

The retracted article, “Novel APC-like properties of human NK cells directly regulate T cell activation,” has been cited 121 times, according to Thomson Scientific’s Web of Knowledge.

The retracted paper examined the early steps of an immune response involving natural killer (NK) cells and antigen-presenting cells (APCs). From the abstract: Read the rest of this entry »

Stem cell researcher in Korea up to half a dozen retractions

without comments

stem cellsAlmost two years ago, we brought you — with the help of Trevor Stokes — the story of a stem cell researcher in Korea whose publication record, and career, unraveled after evidence of image manipulation surfaced in her work.

We’ve reported on four retractions, all in Antioxidants & Redox Signaling, by Soo-Kyung Kang, formerly of Seoul National University resulting from the efforts of a whistleblower. There has been another in Human Gene Therapy: Read the rest of this entry »

Stem cell scientist says data in retracted paper “is not falsified or fabricated”

with 17 comments


Gerold Feuer, via Upstate

On Wednesday, we brought you the story of a retraction by Gerold Feuer, a State University of New York (SUNY) Upstate Medical Center stem cell scientist whom the university had found to have misused grants. He was suspended, but successfully fought that action. We had asked Feuer for comment at that time, and he has now responded:

SUNY Upstate Medical University’s decision to widely publicize the recent decision by the journal Stem Cells to retract an article from my laboratory is a vindictive and retaliatory campaign to defame my scientific credentials in the press and to my scientific colleagues.

I unequivocally state that the data in all published manuscripts is valid and sound and is not falsified or fabricated. SUNY UMU unilaterally requested a retraction from Stem Cells, despite the fact that the federal Office of Research Integrity (ORI) has not yet ruled on these allegations. It is not surprising that UMU has decided to publicize this retraction in a public forum as a second attempt to force me from my tenured faculty position and circumvent decision of the employment arbitrator and the New York Supreme Court.

To date SUNY UMU has refused to abide by the arbitrator’s “binding” decision to reinstate my faculty position and has failed to pay proper back-wages. The arbitrator evaluated operations of my spin-off company, Humurine Technologies, and stated: Read the rest of this entry »

Retraction appears for stem cell researcher found to have used funds for his company’s gain

Gerold Feuer in 2008, via Upstate

A stem cell journal is retracting a paper by Gerold Feuer, a researcher at the State University of New York (SUNY) Upstate Medical Center in Syracuse who was also found to have misused grants.

The Feuer story is complicated. Heralded in 2008 for landing $6.2 million in grants from the New York Stem Cell Board, Feuer was suspended in October 2010 while the university investigated allegations he had misused funds, specifically to funnel state dollars to HuMurine, a company he founded in 2008. In December 2010, Upstate said they had found evidence he had committed 53 acts of financial misconduct, and dismissed him.

From an August 2012 court ruling on a case Feuer brought to fight that dismissal: Read the rest of this entry »
