Identification of intramural epithelial networks linked to peribiliary glands that express progenitor cell markers and proliferate after injury in mice
Frank DiPaola, Pranavkumar Shivakumar, Janet Pfister, Stephanie Walters, Gregg Sabla, Jorge A. Bezerra – 22 May 2013 – Peribiliary glands (PBGs) are clusters of epithelial cells residing in the submucosal compartment of extrahepatic bile ducts (EHBDs). Though their function is largely undefined, they may represent a stem cell niche. Here, we hypothesized that PBGs are populated by mature and undifferentiated cells capable of proliferation in pathological states.
