EdU assay of the cell proliferation ability in BEECs. The cells were treated with LPS or Se (4 µM) or co-treated with LPS and Se (1, 2 and 4 µM). #, P < 0.05, ##, P < 0.01 and ##, P < 0.001 vs. the control group; *, P < 0.05, **, P < 0.01 and ***, P < 0.001 vs. the LPS group. The scale bar = 100 μm. All data were presented as the means ± SEM
