Abstract
Disclosed are methods of using a cell-derived extracellular matrix derived in-vitro from cells isolated from amniotic fluid (AFC-ECM) for the maturation of immature cardiomyocytes derived from human induced pluripotent stem cells (immature hiPSC-CMs) in culture forming mature cardiomyocytes. Also disclosed is a cell construct comprising a monolayer of these mature cardiomyocytes on an AFC-ECM useful for cardiotoxicity and/or proarrhythmic screening assays of drug compounds. Also disclosed are methods for determining the cardiotoxicity and/or proarrhythmic effect of a drug compound in vitro using such cell constructs.
