    Abstract

    Ductular Reaction Promotes Intrahepatic Angiogenesis via Slit2-Robo1 Signaling

    In mouse models of liver injury, ductular reaction cells express genes involved in angiogenesis. In vitro, human liver-derived organoids produced SLIT2 and induced tube formation of endothelial cells.
