Triggering heart repair after myocardial infarction is a challenge in regenerative medicine. A study now shows how ERBB2-mediated YAP activation promotes both cardiomyocyte proliferation and epithelial-to-mesenchymal transition (EMT) in adult mice. EMT initiates cardiomyocyte dedifferentiation and migration and together with proliferation promotes cardiac regeneration.
