Abstract

This protocol describes the differentiation of human iPSCs into liver organoids (HLOs) and their culture on Curio Barrier Liver Chips (Curiochips) to model drug-induced liver injury. The system maintains hepatocyte function and CYP450 metabolic activity for up to 28 days and enables rapid detection of hepatotoxicity at physiologically relevant drug concentrations, offering a high-throughput platform for DILI risk assessment in drug development.

Cell source
Human iPSC
Application
Disease modeling; Drug-induced liver injury (DILI) screening and risk prediction
