Representative images of BrdU-immunolabeled coronal sections through the DG of cD2KO and WT mice. BrdU-positive nuclei appear almost exclusively in the SGZ and GCL of mice that were BrdU-injected at P14 or later. When BrdU was injected at P7, many BrdU-positive cells were furthermore found scattered through the hilus and molecular layer of the DG. All slices represent approximately the same position in the rostrocaudal extension of the HC, the age of first BrdU injection is indicated on the left. Scale bar: 50 μm.
