Figure Lengend Snippet: HH pathway inhibition reduces EHBD cell proliferation after acute injury. EHBDs of WT and Gli1 −/− mice were examined 24‐h after operation with H&E (A) and immunofluorescence (B) (proliferating cells, EdU, green; epithelial cells, CK19, red). Proliferating cells were enumerated and compared with WT controls (C). Experimental schema of WT mice treated with the Vehicle (Veh) or HH inhibitor LDE225 (LDE) before sham or BDL operation with analysis after 24 h (D). LDE‐ or Veh‐treated mouse EHBDs were examined with H&E (E) and immunofluorescence (F). Morphometric analysis of LDE‐ or Veh‐treated mice (G) where proliferating cells were enumerated and compared with Veh‐treated controls. Proliferating cells were expressed as a percentage of all epithelial cells in the CK19 + cell compartment. Asterisks mark EHBD lumen; arrows and arrowheads mark epithelial and stromal cells, respectively. The data are presented as the mean ± SEM. *** p < 0.001, **** p < 0.0001. n = 3–5 mice/group. One‐way ANOVA. Scale bars, 50 μm
