Intrahepatic bile ducts are developed through formation of homogeneous continuous luminal network and its dynamic rearrangement in mice

Establishment of the mature IHBD network consists of two sequential events: (1) formation of the continuous luminal network regulated by the Notch-signaling pathway and (2) dynamic rearrangement of the homogeneous network into the hierarchical network induced by increased bile flow resulting from the establishment of hepatobiliary connections.
