Abstract: Provided are: a method for producing biliary epithelial progenitor cells, said method comprising a step for culturing hepatoblasts in a medium containing TGFβ and EGF; and a method for constructing a three-dimensional duct-like structure of biliary epithelial progenitor cells, said method comprising a step for culturing hepatoblasts or biliary epithelial progenitor cells in a medium containing HGF, EGF, a Notch inhibitor and a GSK3 inhibitor in the presence of a three-dimensional scaffold material.
