Abstract
Following the publication of this article, an interested reader drew to our attention that, in the Materials and methods section of the paper, on p. 2608 in the Immunofluorescence subsection, the authors had included a catalog number (cat no. 6487) that belonged to α‑actinin, not α‑smooth muscle actin (α‑SMA). After having investigated this matter with the authors, they were able to confirm that, although both α‑SMA and α‑actinin antibodies were employed in this study to investigate purification of the cardiomyocytes, the catalog number for α‑SMA should have been referenced as ab5694 from Abcam, and the catalog number for α‑actinin from Cell Signaling Technology is #6487. The authors were also able to confirm that staining with α‑SMA was presented in Fig. 1 of their article, and therefore the relevant catalogue number should have been listed on p. 2608 as ab5694 (Abcam) for α‑SMA, not #6487. The authors express their gratitude towards the reader who identified this error, and regret any inconvenience that this mistake has caused.
