Image Problem

A former postdoc in stem cell biologist Amy Wagers' lab at Harvard University, Shane Mayack, has been sanctioned by the US Office of Research Integrity for research misconduct, reports Retraction Watch. Mayack has been found to have improperly manipulated images in two papers, according to the Federal Register.

The papers, a 2010 Nature paper and a 2008 Blood paper, have been retracted. For the Nature paper, Wagers and two of the co-authors signed the notice, though Mayack did not. Mayack has said that the conclusions from the papers are valid, and the Boston Globe's White Coats blog notes that Mayack has neither admitted nor denied wrongdoing.

Through her attorney, Mayack tells Retraction Watch that she is sorry for "mistakes made during the preparation of figures corresponding to some of the work I performed as a postdoc at Harvard Medical School. These were mistakes in representation and presentation of the data, as corroborated by ORI's findings of ‘falsely presented’, and were not due to fabrication, falsification, or plagiarism of scientific results."
