Adult born neurons express the neuron specific marker NT in the SVZ and proximal RMS 12 hours after the final BrdU injection. 40× images of sagittal sections through the olfactory bulb of SVZ showing BrdU (red) and NT (green). Co-localization is seen within the SVZ (A) and the proximal RMS (B). Scale bars, 37 μm. NT, NeuroTrace; SVZ, sub-ventricular zone; RMS, rostral migratory stream, BrdU, bromodeoxyuridine.
