Atrial hiPSC-CM as a pharmacological model to evaluate anti-AF drugs: Some lessons from IKur

Journal of Cardiovascular Pharmacology

Human induced pluripotent stem cells (hiPSC) and atrial hiPSC-derived cardiomyocytes (hiPSC-CM) have entered the arena of preclinical AF research. A central question is whether they reproduce the physiological contribution of atrial selective potassium currents (such as the ultrarapid potassium current, IKur) to repolarization.
