In ovo injection of CHIR-99021 promotes dorsal feather follicles development in chick embryos. (A) Morphological photographs of longitudinal feather follicles between groups as indicated by H&E. The diameter of feather follicles is indicated by black arrows. (B) The statistical results of feather follicle diameter. Scale bars = 50 μm. Statistical significance was determined by Duncan's multiple range test. Values are presented as the mean + SEM. Different letters in a column indicate a significant difference (P < 0.05, n = 60 feather follicles from 6 biological samples).
