Figure 6. IDO1 genetic ablation ameliorates neurogenesis in mice under CUMS treatment. (A, C) Immunostaining and the relative fluorescence intensity of the DCX in the hippocampus of WT and Ido1-/-groups. (B, D) Immunostaining and the relative fluorescence intensity of the Nestin in the hippocampus of WT and Ido1-/-groups. (scale bar 100 μm). n = 6 mice/group. Bars represent mean±SEM. * p< 0.05, **p< 0.01.
