Deltamethrin exposure reduces the number of nestin+ cells in the dentate gyrus (DG) in hippocampus of adult mice. . Immunostaining of nestin (dark brown) in the DG region of the hippocampus (A). The number of nestin+ cells is presented in bar graphs (B). An unpaired t test was used to determine significant difference between control and treatment. The values represent mean cell number ± SEM per section from 10 sections per animal and 5 animals per group. Asterisk indicates significantly different from control (t = 5.68; df = 8; p < .01). Abbreviations: GCL, granule cell layer; H, hilus; SGZ, subgranular zone. Scale bar = 1600 µm. Inset scale bar 200 µm.
