Figure Lengend Snippet: Histological alterations in the cornea at different time points after lacrimal gland excision. (A) Light microscopy images of the central cornea after hematoxylin and eosin staining for the sham side at 1 week post-surgery and the excision side at 1, 4 and 8 week post-surgery (Left panel: original magnification, × 40; scale bar, 50 μm. Right panel: magnified images within the dashed line in the left panel.). The arrow indicates the neovascular formations in the stroma. (B) Quantitative analysis of the number of cell nuclei in the stroma. Results are presented as the mean ± SEM ( n = 5 for each group. Statistical significance was assessed using two-way ANOVA, * P < 0.05 and ** P < 0.01, versus the sham side; ## P < 0.01 versus 1-week post-surgery). (C) Light microscopy images of the central cornea after tubulin βIII–immunostaining for the sham side at 1 week post-surgery and the excision side at 1, 4, and 8 weeks post-surgery (Left panel: original magnification, × 40; scale bar, 50 μm. Right panel: magnified images within the dashed line in the left panel.). (D) Quantitative analysis of the tubulin βIII-positive area in the epithelium, representing nerve density. Each column and the vertical bar represent the mean ± SEM ( n = 5 for each group; Two-way ANOVA, * P < 0.05 compared to the sham side, and ## P < 0.01 compared to the 1-week post-surgery).
Article Snippet: For immunohistochemical staining, the sections were incubated for overnight at 4°C with an anti-tubulin βIII mouse monoclonal antibody (sc-80005; Santa Cruz Biotechnology, Dallas, TX, USA) diluted 1:200, an anti-Sema3A mouse monoclonal antibody (sc-74554, diluted 1:1000; Santa Cruz Biotechnology) and an anti-Sema7A mouse monoclonal antibody (sc-374432, diluted 1:400; Santa Cruz Biotechnology).
