The establishment of self-renewing hepatoblast-like cells (HBCs) from human pluripotent stem cells (PSCs) would realize a stable supply of hepatocyte-like cells for medical applications. However, the functional characterization of human PSC-derived HBCs was not enough. To purify and expand human PSC-derived HBCs, human PSC-derived HBCs were cultured on dishes coated with various types of human recombinant laminins (LN). Human PSC-derived HBCs attached to human laminin-111 (LN111)-coated dish via integrin alpha 6 and beta 1 and were purified and expanded by culturing on the LN111-coated dish, but not by culturing on dishes coated with other laminin isoforms. By culturing on the LN111-coated dish, human PSC-derived HBCs were maintained for more than 3 months and had the ability to differentiate into both hepatocyte-like cells and cholangiocyte-like cells. These expandable human PSC-derived HBCs would be manageable tools for drug screening, experimental platforms to elucidate mechanisms of hepatoblasts, and cell sources for hepatic regenerative therapy.
