GATA4 and myocardial infarction: The overexpression of exosomes derived from GATA binding factor 4 (GATA-4) bone marrow mes-enchymal stem cells can not only induce the differentiation of bone marrow mesenchymal stem cells (BMSCs) into cardiomyocyte-like cells by upregulating the expression of cardiomyocyte-specific antigens, cardiac troponins T (cTnT), Connexin-43, and Desmin; they can also inhibit cardiomyocyte apoptosis, in-creasing the ejection fraction of the exosome-treated group after myocardial infarction to improve cardiac function in vivo (79).
