GATA4 and myocardial infarction: Porcine dECM scaffold, when seeded with adipose tissue-derived progenitor cells, has shown to express endothelial marker isolectin B4 as well as cardiac markers including GATA4, connexin43 and cardiac troponin T. The cardiac dECM seeded with ATDPCs and ATMSCs, when implanted in a porcine MI model, has promoted neovascularization of the ischemic myocardium and resulted significant restoration of ventricular cardiac function
