A group of Harvard stem cell researchers who already have one retraction and an expression of concern now have a correction. This one’s in Circulation Research, and it involves an image that previously had been flagged as suspicious in our comments.
The group is led by Piero Anversa, who as we reported last year is one of two researchers suing Harvard because the institution’s investigation into their work
has cost them millions in a forfeited sale of their company, and job offers.
As Boston news outlets reported at the time, Anversa and his colleague, Annarosa Leri, claim their
professional reputations and careers have been shattered by an inquiry and investigation process that has been conducted contrary to federal regulation and institutional policies, and has been publicly disclosed by Defendants.
Leri and Anversa are co-authors of the Circulation Research article, titled “Insulin-Like Growth Factor-1 Receptor Identifies a Pool of Human Cardiac Stem Cells With Superior Therapeutic Potential for Myocardial Regeneration.” Here’s the notice:
In the Circulation Research article by D’Amario et al (Insulin-Like Growth Factor-1 Receptor Identifies a Pool of Human Cardiac Stem Cells With Superior Therapeutic Potential for Myocardial Regeneration. Circ Res. 2011;108:1467–1481. DOI: 10.1161/CIRCRESAHA.111.240648), a correction was needed.
During the course of an ongoing investigation, questions were raised about Figure 7I in the article, which may not adequately reproduce the originally acquired image. Accordingly, the authors have generated a new figure using data from the same sample. The new figure demonstrates the same findings as the original figure, and it does not change the conclusions of the published article.
The authors regret this circumstance. This correction been noted and updated in the online version of the article, which is available at http://circres.ahajournals.org/content/108/12/1467.full.
