ELA leads to diminished proliferation of OLs, which can be rescued by early PBM treatment. A (a-c) and B (a-c) Representative immunofluorescence staining for Ki67+ (green) - labeled OLs (Olig2+, red) in CA1 region of the hippocampus, small images exhibit a representative single cell from each group. (A) (d) and B (d) Percentage of Ki67+ - labeled OLs (Ki67+ Olig2+ cells) in the total Olig2+ cells. ELA-exposured rats exhibited a dramatic decrease in the proportion of newly differentiated OLs, while PBM-treated ELA rats showed normal differentiation capacity. Scale bar = 40 µm. All data are presented as mean ± SE (n = 5-7). * P < 0.05 versus Control-group; # P < 0.05 versus ELA-group.
