Immunohistochemistry of Ki-67 in the dentate gyrus. Upper panels show the localization of the region shown in the lower panel. Nuclei with KI-67-positive were mainly detected in the subgranular zone (SGZ) of the dentate gyrus, which is shown in the lower panel of d. Brown nuclear stain highlights KI-7-positive cells. The Ki-67-positive nuclei were seen more in the TRD (c) and CD (d) groups, and the cells were less seen in the control (a) and KD (b) groups
