Expression patterns of Nogo-A and NgR1 in the adult SVZ–OB system. A, A′, Anti-Nogo-A and anti-NgR1 labeling appear complementary in both the DH–SVZ (A) and the RMS (A′). B–D, Nogo-A labeling identifies DCX-expressing neuroblasts in the DH–SVZ (B), RMS (C), and LW (D). E, Quantifications of Nogo-A and DCX coexpression in the SVZ–OB system (n = 5). F–G′, The astrocytic marker GFAP and NgR1 colocalize in germinal astrocytes. H, Quantification of NgR1 and GFAP coexpression in the SVZ–OB system (n = 5). I–L, Absence of costaining for Nogo-A and GFAP, or NgR1 and DCX. Error bars indicate SEM. Scale bars: A, A′, F, F′, I, J, 30 μm; B–D, K, I, 20 μm.
