ERBB2 and myocardial infarction: Recent studies have highlighted that in the process of cardiac regeneration mediated by ErbB2 in an adult murine model of MI, an epithelial-mesenchymal transition (EMT)-like process is also involved; thus, the authors suggested that CM migration is an essential element for cardiac repair and scar replacement by new CMs, together with ECM and cytoskeletal remodelling.
