ABSTRACT
In vitro hepatocyte cell models are being used to study the pathogenesis of liver disease and in the discovery and preclinical stages of drug development. The culture of hepatic cell lines and primary hepatocytes as in vitro cell models has been carried out for several decades. However, hepatic cell lines (hepatic carcinoma generated or immortalized) have limited accuracy when recapitulating complex physiological functions of the liver. Additionally, primary hepatocytes sourced from human cadavers or medical biopsies are difficult to obtain due to sourcing limitations, particularly for large-scale population studies or in applications requiring large number of cells. Hepatocyte cultures differentiated from human embryonic stem cells (ESCs) and induced pluripotent stem cell (iPSCs) overcome in large part the limitations of traditional hepatocyte in vitro models. In this chapter, we described an efficient protocol routinely used in our laboratory to differentiate human iPSCs into functional hepatocyte cultures for in vitro modeling of liver function and disease. The protocol uses a three-stage differentiation strategy to generate functional hepatocytes from human iPSCs. The differentiated cells show characteristic hepatocyte morphology including flat and polygonal shape, distinct round nuclei, and presence of biliary canaliculi and they express hepatic markers alpha-fetoprotein (AFP), albumin (ALB), E-cadherin (CHD1), hepatocyte nuclear factor 4 alpha (HNF4α), and actin.
