Transplantation of Human-induced Pluripotent Stem Cell-derived Cardiomyocytes Is Superior to Somatic Stem Cell Therapy for Restoring Cardiac Function and Oxygen Consumption in a Porcine Model of Myocardial Infarction.

ABSTRACT: BACKGROUND:Somatic stem cell (SC) therapy can improve cardiac performance following ischemic injury. In this study, we investigated whether induced pluripotent SC-derived cardiomyocytes (iPS-CMs) are more effective than somatic SCs, such as skeletal myoblasts (SM) and mesenchymal (M)SCs, in promoting functional recovery upon transplantation in a porcine model of myocardial infarction. METHODS:Myocardial injury was induced by ameroid ring placement in immunosuppressed female mini pigs; after 1 month, epicardial cell transplantation was performed with iPS-CMs (n = 7), SMs (n = 7), and MSCs (n = 7). Control pigs underwent sham operation (n = 8). RESULTS:Cell therapy improved functional recovery 2 months after myocardial infarction, as evidenced by increased ejection fraction (iPS-CM, +7.3% ±
