Abstract: Described herein are compositions and methods relating to the improvement of cardiac function. Various embodiments relate to transplant compositions comprising cardiomyocytes which are engineered to be non-contractile, and to methods of using such cardiomyocytes or transplant compositions to improve cardiac function, e.g., by administering them to cardiac tissue.

Abstract: Described herein are compositions and methods related to the treatment of a cardiovascular disease or disorder. Also described herein are cells, stem cells (including embryonic and pluripotent stem cells), and in vitro-differentiated human cardiomyocytes in which HCN4 (HCN4), Cav3.2 (CACNA1H) and NCX1 (SLC8A1) activities are at least partially inhibited, and Kir2.1 (KCNJ2) activity is at least partially stimulated in such cells. Also described herein are formulations for the delivery of such cells and methods of transplanting cardiomyocytes, e.g., for the treatment or prevention of a disease or disorder.
