Functional characteristics of induced pluripotent stem cell-derived cardiomyocytes (iPS-CMs) and neonatal cardiomyocytes (N-CMs). (A) Representative action potential (AP) recording traces of iPS-CMs showing the positive and negative chronotropic response to isoproterenol and carbachol application, respectively. (B) AP recordings from spontaneously beating N-CMs.
