Retraction of: Tracking Chromatid Segregation to Identify Human Cardiac Stem Cells That Regenerate Extensively the Infarcted Myocardium

For the article “Tracking Chromatid Segregation to Identify Human Cardiac Stem Cells That Regenerate Extensively the Infarcted Myocardium” (Circ Res. 2012;111:894–906; DOI: 10.1161/CIRCRESAHA.112.273649) by Jan Kajstura, Yingnan Bai, Donato Cappetta, Junghyun Kim, Christian Arranto, Fumihiro Sanada, Domenico D’Amario, Alex Matsuda, Silvana Bardelli, Joao Ferreira-Martins, Toru Hosoda, Annarosa Leri, Marcello Rota, Joseph Loscalzo, and Piero Anversa, an investigation by Harvard Medical School and Brigham and Women’s Hospital (BWH) has determined that there were issues with some of the data reported in the article, specifically Figure 2E. An expression of concern was published on November 20, 2018,¹ to alert readers that the American Heart Association was communicating with the authors and reviewing the materials provided by BWH. After considering input from authors, the American Heart Association has determined that the best interest of the public and the research community will be served by issuing this notice of retraction.

The American Heart Association, therefore, retracts the article.
