OECs are closely associated with axons in the ONL. Immunohistochemistry in OB sections of S100-GFP mice (P26). A and B, OB layers indicating the locations shown at higher magnification to the right (square). ONL: Olfactory nerve layer; GL: glomerular layer; EPL: external plexiform layer. Nuclei were stained with DRAQ5. A′-A‴, Colocalization of GFP (green) with BLBP (red) in OECs. Insets: higher magnifications of the area inside the dashed square; Scale bar = 5 μm. Filled arrowheads: OEC fine processes; open arrowhead: OEC cell body; asterisk: next to endothelial cell. PGs: Periglomerular cells. B′-B‴, Immunoreactivity for NCAM, a marker for OSN axons (red), is in the lacunae (asterisks) defined by the matrix of fine OEC processes (arrowheads).
