The sentence should read: Furthermore, it has been recently demonstrated that CDCs limit acute injury by polarizing an effector macrophage population within the heart.A reference is omitted from the fourth sentence of the third paragraph of the Introduction, the second sentence of the fourth paragraph of the Introduction, and the second sentence of the third paragraph of the Discussion.The reference is: de Couto G, Liu W, Tseliou E, Sun B, Makkar N, Kanazawa H, Arditi M, Marbán E. Macrophages mediate cardioprotective cellular postconditioning in acute myocardial infarction. J Clin Invest. 2015;125:3147–62. doi: 10.1172/JCI81321.The fourth sentence of the third paragraph of the Introduction should read: Furthermore, it has been recently demonstrated that CDCs limit acute injury by polarizing an effector macrophage population within the heart (de Couto et al., 2015).The second sentence of the fourth paragraph of the Introduction should read: Similar to previous study (de Couto et al., 2015), results showed that CDCs-conditioned medium significantly promotes the macrophages to shift into a regulatory (M2) phenotype.The second sentence of the third paragraph of the Discussion should read: The immunomodulation property of MSCs has been demonstrated by previous studies, and a recent study has already demonstrated the potential role of CDCs for polarizing macrophages [18-21] (de Couto et al., 2015).There are errors in the Author Contributions.
