Corneal and conjunctival epithelial cell apoptosis in the NC groups, PBS-treated groups, and PM2.5-treated groups. Representative images for the TUNEL assay of the corneal epithelium and conjunctival epithelium on day 14 (A). Only a few apoptotic cells were observed in the superficial layer of the corneal and conjunctival epithelium in the control groups, while much more apoptosis was recorded in corneal and conjunctival superficial and basal epithelium after PM2.5 treatment (P < 0.05, B,C). The data are presented as the mean ± the SD, n = 5. *P < 0.05 vs. control, vP < 0.05 vs. PBS.
