p75^NTR expression in BrdU-positive SGZ cells, 10 hours post-BrdU injection. Dentate gyrus coronal sections harvested from p75^NTR (+/+) mice 10 hours after a single BrdU injection were co-immunostained with antibodies against BrdU (red) and p75^NTR (green). Confocal microscope Z-stacks were collected at 40 × magnification with an interval of 1 μm between planes with a total of 6 image planes collected from each section. The typical appearance of SGZ fields is shown here. Scale bar (lower right panel): 2 μm.
