WT1 and myocardial infarction: For cardiac repair post-myocardial infarction, Wt1+ epicardial cells consist of multipotent cardiac stem cells that can give rise to de novo cardiomyocytes [105] and vascular progenitor cells contributing to angiogenesis [106], which undergo epithelial-to-mesenchymal transition (EMT) to migrate into the infarcted area to repair and repopulate the region [78].
