Establishment of a Drug-Induced, Bile Acid–Dependent Hepatotoxicity Model Using HepaRG Cells

Bile acid (BA) retention within hepatocytes is an underlying mechanism of cholestatic drug-induced liver injury (DILI). We previously developed an assay using sandwich-cultured human hepatocytes (SCHHs) to evaluate drug-induced hepatocyte toxicity accompanying intracellular BA accumulation. However, due to shortcomings commonly associated with the use of primary human hepatocytes (e.g., limited availability, lot-to-lot variability, and high...
