Shane Mayack, a former post-doc in Harvard lab of Amy Wagers, a rising star in the stem cell field, has been sanctioned by the Office of Research Integrity for misconduct.
Mayack, who has defended her actions on this blog as honest error — albeit sloppiness — and has not admitted to wrongdoing, must undergo supervision if she receives any federal grant funding over the next three years, under the voluntary agreement.
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 has not spoken to the press, except for a brief comment to Naturethrough her attorney.
Here, we present, unedited, Mayack’s side of the story. While accepting responsibility, she also has a number of suggestions for how universities and journals can handle these situations better. Shane can be reached at smayck[at]yahoo.com.
Since it was well covered by this blog, the readers of Retraction Watch are no doubt aware that in October 2010, a paper that I co-authored was retracted from Nature and a notice of concern was posted regarding a second paper published in Blood.
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 a re-examination of the publication raised serious concerns with some of the reported data. These concerns have undermined the authors’ confidence in the support for the scientific conclusions reported, specifically the role of osteopontin-positive niche cells in the rejuvenation of haematopoietic stem cells in aged mice. Although this matter is under further review, these authors wish to retract the paper in its entirety, and regret any adverse consequences that may have resulted from the paper’s publication. The retraction has not been signed by Shane R. Mayack, who maintains that the results are still valid.
