Tg(krt18:egfp) is expressed at all levels of the developing intrahepatic and extrahepatic biliary system. (A–C) Confocal projections of dissected livers from 3, 4, and 5 dpf Tg(krt18:egfp) fish, indicating biliary proliferation and remodeling (400× magnification). Arrow in panel A indicates rudimentary gallbladder. (D–E) Confocal projections from dissected liver of 5 dpf Tg(krt18:egfp) larva stained with (D) anti-GFP and (E) anti-Mdr to mark biliary cells and hepatocyte canaliculi, respectively. (F) Merged projection from panels D and E, demonstrating colocalization of canaliculi with GFP-positive terminal ductules (D–F: 630× magnification).
