In the article by Sanada et al, “c-Kit–Positive Cardiac Stem Cells Nested in Hypoxic Niches Are Activated by Stem Cell Factor Reversing the Aging Myopathy,” which published online before print October 29, 2013, and appeared in the January 3, 2014, issue of the journal (Circ Res. 2014;114:41–55. DOI: 10.1161/CIRCRESAHA.114.302500), a correction is needed.
Questions were raised about Figures 3A, 3C, and 4B in the article. The antibody employed for the detection of Ki67 was a rat monoclonal while the antibodies utilized to identify Nkx2.5 and GATA4 were goat polyclonal. It was appropriate to use the same isotype control for Nkx2.5 and GATA4, but a different isotype control was introduced for the analysis of Ki67. A mistake was made in the assembly of Figures 3A, 3C, and 4B. The similarity in the FACS plots resulted in an error, which has been corrected in the revised figures. For clarity, plots collected at the same time have been selected. The legends to Figures 3A, 3C, and 4B remain unchanged.
The authors regret this circumstance.
