New neurons are generated in the amygdala nuclei in vivo. (a) BrdU-labeled cells (red, arrows) are present in the basolateral amygdala (BLA) in adult mice. CeA: central amygdala (b) An example of BrdU-labeled cells (red) co-expressing the immature neuronal marker DCX (green) in the BLA. All nuclei are labeled with DAPI (blue). (c) An example of DCX-GFP+ cells (green) in the BLA that are co-labeled with BrdU (red). The merged image and orthogonal views are shown on the far right. (d) DCX-GFP−, BrdU+ cells co-labeled with the mature neuronal marker NeuN in the BLA 4 weeks after the last BrdU injection. (e) A BrdU-labeled cell co-expressing DCX-GFP and NeuN. Scale bars, 50 μm in (a) and 10 μm in (b–e).
