Extended Data Figure 6.

Identity of immigrant BrdU⁺ cells in the olfactory bulb (OB). a, Some BrdU⁺ cells in the glomerular layer (gl), visualized 35 days after injection of BrdU (red) and presumed immigrant descendants of SVZ cells in S phase at the time of injection, are also positive for tyrosine hydroxylase (green) in both WT (left panel) and Axl^−/−Mertk^−/− (right panel) mice. Arrowheads are examples of TH⁺BrdU⁺ cells. b, Similar comparative granule cell layer (gcl) sections stained with anti-BrdU (red) and calretinin (CR, green). Arrowheads are examples of CR⁺BrdU⁺ cells. Panels co-stained with Hoechst 33258 to visualize nuclei. Scale bars 50 μm. Representative images of n = 2 per genotype.
