Fig. 6. AC affected hippocampal neurogenesis. Representative DG immunohistochemical sections at 4 weeks following injection with vehicle- or AC-treated group. (A) BrdU and (B) DCX immunostaining. The number of BrdU- or DCX-positive cells in the DG was significantly decreased 4 weeks after AC treatment. Scale bars represent 50 µm. Data are expressed as means±SEs. ^*p<0.05, ^**p<0.01 vs. vehicle-treated controls. GCL, granular cell layer; SGZ, subgranular zone.
