Safety and Engraftment of Aligned Cardiac Patches Loaded with hiPSC-CMs in a Large Animal Model of Myocardial Infarction.

ABSTRACT: Myocardial infarction (MI) is a leading cause of death in the United States. Human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) present a promising strategy for regenerating the damaged heart tissue post-MI. However, poor cell engraftment and survival remain significant barriers in their effective use for myocardial repair. In this study, we developed a "cardiac patch" using a bi-layered, aligned coaxial patch for epicardial delivery of hiPSC-CMs in a preclinical porcine MI model. The cardiac patch (40 mm in diameter and 500 µm thick) was fabricated using polycaprolactone (PCL) and gelatin via electrospinning and seeded with twenty-two million hiPSC-CMs. In vitro functional assessment showed synchronized contractility of the hiPSC-CMs along the aligned fibers.
