Subsequently to the publication of the above article, the authors have realized that Fig. 3 was published with an error: Essentially, the image selected for Masson's staining of the Leonurine group in Fig. 3A (the right-hand panel) was inadvertently selected from Fig. 4 in an article published previously by the same group [Zhu H, Jiang X, Li X, Hu M, Wan W, Wen Y, He Y and Zheng X: Intramyocardial delivery of VEGF165 via a novel biodegradable hydrogel induces angiogenesis and improves cardiac function after rat myocardial infarction. Heart Vessels 31: 963–975, 2016]. However, owing to the time that has elapsed since this article was published, the authors no longer had access to their original data; therefore, they were granted permission by the Editor to repeat the experiments shown in Fig. 3, and the revised version of Fig. 3 is shown below.

Figure 3. Collagen content 28 days after myocardial infarction. (A) Representative pictures of left ventricles from each group after Masson's Trichrome staining (magnification, ×200). (B) Collagen content as percentages at 28 days. Collagen content is calculated from the ratio of the collagen area to the area of the entire high-power field. The data are expressed as the mean ± standard deviation. *P<0.05 vs. sham, #P<0.05 vs. NS. n=6 in each group. NS, saline group.
