    IP3R-Mediated Compensatory Mechanism for Calcium Handling in Human Induced Pluripotent Stem Cell-Derived Cardiomyocytes with Cardiac Ryanodine Receptor Deficiency

    Researchers found that type 2 ryanodine receptor (RYR2)–/–-iPSCs could differentiate into cardiomyocytes (CMs) with the efficiency similar to control-iPSCs; however, the survival of induced pluripotent stem cell-CMs were markedly affected by the lack of functional RYR2.

    Abstract

    Selective Protection of Human Cardiomyocytes from Anthracycline Cardiotoxicity by Small Molecule Inhibitors of MAP4K4

    The authors report successful protection from doxorubicin in two independent human pluripotent stem cell-derived cardiomyocyte lines, using two potent, highly selective MAP4K4 inhibitors.
