Abstract

The quest for physiologically active human hepatocyte-like cells for in vitro research and drug screening is high. The recent progress in the field of pluripotent stem cell (PSC)-derived hepatic cells within the last decade brings those cells closer to applications in translational medicine. However, the classical two-dimensional (2D) cell culture systems are of limited use, because relevant cell-cell interactions based on cell polarity, which is a major prerequisite for proper hepatic cell metabolisms, are not provided. In this study, we report a scalable 3D suspension culture system, in which PSC-derived hepatic cells can be maintained for up to 3 weeks with stable gene expression profiles and metabolic features in a suspension culture system ranging from a 1.5 mL up to a 15 mL. Adjustments of culture conditions and, most importantly, the size of the organoids resulted in the robust generation of hepatic organoids consisting of a quite homogenous cell population. Importantly, the generation of these hepatic organoids was highly reproducible and allowed, in contrast to hepatic PSC derivatives in 2D culture conditions, a sensitive assessment of acetaminophen-related toxicity, the most common source for drug-induced liver failure.
