BODY-ON-A-CHIP: ON-CHIP HEART RECEIVING METABOLITES FROM ON-CHIP LIVER

Abstract

International audienceWe report on the development of an integrated microfluidic and multi-electrode array (MEA) system housed in a microbioreactor for Body-on-a-Chip applications. On a single chip, we successfully demonstrate the use of this system by connecting an on-Chip Liver and an on-Chip Heart. We demonstrate that acylated dihydropyrimidinone (DHPM), when added to the on-Chip Liver, is deacylated and results in DHPM, a well-known calcium channel blocker, delivered to the on-Chip Heart by on-Chip organ-to-organ interconnectivity. Deacylated DHPM delivery to the cardiomyocytes is verified by MEA measurements of cardiomyocyte electroactivity and Liquid chromatography-mass spectrometry (LCMS) of the cardiomyocyte medium
