a Histology by Periodic acid-Schiff (PAS) staining of the conjunctival epithelium in WT mouse. In the conjunctiva, epithelial cells and subepithelial fibroblasts are seen. PAS positive goblet cells were distributed in the conjunctival epithelium (arrows). Bar, 50 µm. b Expression pattern of phsopho-Stat3 in ocular surface. Immunoreactivity for phospho-Stat3 was not observed in the corneal epithelium and keratocytes of both WT and KO mice as well as in the WT conjunctiva(A, B). However, phospho-Stat3 immunoreactivity was detected in fibroblasts (arrows) in the subepithelial connective tissue of KO mice (D, higher magnification in D’), but was not seen in the WT tissue (C, higher magnification in C’) Bar, 10 µm.
