B Confocal image of an adult DG populated by distinct cells identified by cell type-specific protein expression and morphology. All cells newly-generated within the 12 days incorporated BrdU (magenta); rNSCs were identified by expression of SOX2 (cyan), localization of their cell bodies to the SGZ, and a GFAP+ radial process (green); IPCs were located within the SGZ and express SOX2 only (cyan); neuroblasts in the SGZ and GZ were labelled by DCX (white; arrows); astrocytes in the hilus, GZ, and ML (arrowheads) expressed SOX2 (cyan). C Quantification of the percentages of generated cell types out of all generated cells (rNSCs, IPCs + neuroblasts, astrocytes) in the DG. Data information: All data are represented as mean ± SEM; number of experimental animals (indicated by red dots): (C n = 5 ; dotted lines border SGZ and GZ; scale bars = 50 µm (B
