Abstract
We propose a method for constructing fiber-type three-dimensional (3D) tissue of human iPS-derived cardiomyocytes and quantifying its contractile force in response to the addition of drug. By culturing the cardiomyocytes in micropatterned hydrogel with anchors, we succeeded in fabrication of the fibers with aligned cardiomyocytes and fixation of the fiber edges to the anchors. Since the fiber generated contractile force in a single direction due to alignment of cardiomyocytes, we can measure the contractile force accurately. Furthermore, as a demonstration of drug testing, we quantified contractile frequency and force in accordance with concentrations of pilsicainide. We believed that the fiber of human iPS-derived cardiomyocytes will be used in pharmacokinetic applications for drug development.
