The effect of Se on the cell migration rate of the BEECs by using the scratch wound healing assay. The cells were treated with LPS or Se (4 µM) or co-treated with LPS and Se (1, 2 and 4 µM) and observed under light microscopy at 100× magnification. The yellow lines indicate the cell margins at each time point. The cell migration rate = (scratch width at 0 h – scratch width at 6 or 12 or 24 h)/scratch width at 0 h × 100%. #, 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. All data were presented as the means ± SEM
