Figure 6. Immunofluorescent staining with TNF-α specific antibody (red) in corneal epithelia (CE: arrows) and conjunctival epithelia (CJE: arrowheads) were detected in FML-treated mice at 1 week BTX-B post-injection, and decreased significantly at 2 and 4 weeks post-injection compared to other groups (D-F and J-L with nuclear counterstain in blue). Images of isotype and negative control were omitted (no staining). Scale bar: 50 µm.
