However, the underlying mechanisms for cardiac patch repairing infarcted myocardium remain unclear. In this study, we investigated the mechanisms of PCL\/gelatin patch loaded with MSCs on activating endogenous cardiac repair. PCL\/gelatin patch was fabricated by electrospun. The patch enhanced the survival of the seeded MSCs and their <jats:italic>HIF\u20101<\/jats:italic>\u03b1, <jats:italic>T<\/jats:italic>\u03b2<jats:italic>4<\/jats:italic>,<jats:italic> VEGF<\/jats:italic> and <jats:italic>SDF\u20101<\/jats:italic> expression and decreased <jats:italic>CXCL14<\/jats:italic> expression in hypoxic and serum\u2010deprived conditions. In murine MI models, the survival and distribution of the engrafted MSCs and the activation of the epicardium were examined, respectively. At 4 weeks after transplantation of the cell patch, the cardiac functions were significantly improved. The engrafted MSCs migrated across the epicardium and into the myocardium. Tendency of <jats:italic>HIF\u20101<\/jats:italic>\u03b1, <jats:italic>T<\/jats:italic>\u03b2<jats:italic>4<\/jats:italic>,<jats:italic> VEGF<\/jats:italic>,<jats:italic> SDF\u20101 and CXCL14<\/jats:italic> expression in the infarcted myocardium was similar with expression <jats:italic>in vitro<\/jats:italic>. The epicardium was activated and epicardial\u2010derived cells (EPDCs) migrated into deep tissue. The EPDCs differentiated into endothelial cells and smooth muscle cells, and some of EPDCs showed to have differentiated into cardiomyocytes. Density of blood and lymphatic capillaries increased significantly. More c\u2010kit<jats:sup>+<\/jats:sup> cells were recruited into the infarcted myocardium after transplantation of the cell patch. The results suggest that epicardial transplantation of the cell patch promotes repair of the infarcted myocardium and improves cardiac functions by enhancing the survival of the transplanted cells, accelerating locality paracrine, and then activating the epicardium and recruiting endogenous c\u2010kit<jats:sup>+<\/jats:sup> cells. Epicardial transplantation of the cell patch may be applied as a novel effective MI therapy.<\/jats:p>","DOI":"10.1111\/jcmm.13097","type":"journal-article","created":{"date-parts":[[2017,2,28]],"date-time":"2017-02-28T13:26:09Z","timestamp":1488288369000},"page":"1751-1766","source":"Crossref","is-referenced-by-count":84,"title":["Mesenchymal
