Abstract
The pharmaceutical industry is evolving with the use of human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CM) for in vitro cardiac safety screening. Traditional reliance on QT-interval prolongation as a main arrhythmogenicity marker is being challenged. In addition, the Comprehensive In Vitro Proarrhythmia Assay (CiPA) initiative recommends using computer modeling and in silico platforms as a more comprehensive approach for arrhythmogenicity testing in conjunction with hiPSC-CM in vitro screening. Our study presents an innovative platform that integrates in vitro hiPSC-CM propagation test with in silico models to assess the potential arrhythmogenic effect of drug-induced impact on ionic currents and electrophysiological intercellular coupling. Utilizing the electrophysiological and morphological characteristics of hiPSC-CM, we offer a thorough evaluation of potential drug-induced cardiac risks by computer modeling. We show, using the examples of lidocaine (100-300μM) and Cyclophosphamide (639, 852μM), that with the use of an integrative experimental and computer platform, it is possible to correctly display the clinical manifestations of side effects in advance.
