Fig. 4: Characterization of plexin-B3 + aOPCs in vivo.

a Immunohistochemical analysis of plexin-B3 (blue) and NG2 (brown) in the adult rat hippocampus. Arrows: plexin-B3+ aOPCs. Scale bar: 200 μm. b Distribution of plexin-B3+ aOPCs in an adult rat brain section (red dots). c Morphologies of plexin-B3+ aOPCs in the corpus callosum. Scale bar: 20 μm. d Fluorescent immunostaining of plexin-B3, olig2, and NG2 in the cortex. Scale bar: 20 μm. e Fluorescent immunostaining of plexin-B3 and MBP in the cortex. In d and e, nuclear staining (blue) is shown in the merged panels. Scale bar: 20 μm. f Fluorescent immunostaining of plexin-B3 and BrdU in the cortex. Scale bar: 20 μm.
