Abstract

Induced pluripotent stem cells (iPSCs) hold great promise for cell therapy including for replacing damaged cardiomyocytes after a myocardial infarction. However, preclinical studies should be performed to evaluate the feasibility, safety and efficiency of this approach. The aim of this project is to test the hypothesis that transplantation of pig iPSC-derived cardiac cells prevents deterioration of the cardiac function post myocardial infarction in pigs. The major limitation in the use of pig iPSCs for translational cardiac cell therapy studies is the inefficiency of the differentiation of these cells into cardiomycoytes. Based on a strong laboratory expertise on pig iPSC generation, characterization and human cardiomyocyte differentiation, the first specific aims will be the enhancement of pig cardiomyocyte differentiation protocol and the generation of pig iPSC-derived cells which are non-fully differentiated but cardiac committed cells, which we speculate would be the most suitable for transplantation. We plan to test 3D culture systems to increase the potential of pig cells before transplantation and to transplant the cells into a pig model of closed-artery catheter-based myocardial infarction developed in the laboratory. This work would be of significant interest to the field and help for the acceleration of the transition of iPSC-based cell therapy for cardiac regeneration from bench to clinics. (AU)
