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

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 (MI). 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 MI, as evidenced by increased ejection fraction (iPS-CM, +7.3% ± 2.2% and SM, +5.8% ± 5.4% vs. Control: -4.4% ± 3.8%; P
