Cardiovascular diseases are the leading cause of death around the globe. Despite ongoing progress, a shortage in the primary source of human cardiac tissue still presents a major limiting factor in relevant research. Human induced pluripotent stem cells (iPSCs) hold great promise in cardiovascular disease mechanistic research and treatment as they can provide an unlimited supply of cardiomyocytes. Nevertheless, so far, the cardiomyocytes derived from human iPSCs disproportionately rec...
