Establishment of a mouse model for bile duct repair and tissue engineering

Abstract Due to the lack of a suitable model, research on biliary biology is far behind that on other organs. A mouse model of common bile duct (CBD) dilation (BDD) was first established and compared with CBD ligation mice (BDL). Then, in a transplantation experiment, the dilated CBD of recipient BDD mice was injured by making an elliptical incision and repaired by transplanting a bile duct patch from donor BDD mice. Biochemical and histological changes were analyzed and cell proliferation
