FIGURE 3.
Expression of olig2:GFP in the adult zebrafish spinal cord marks OPCs in the parenchyma and a subpopulation of ventral radial glia at the central canal. OPCs are evenly distributed throughout the parenchyma in an unlesioned zebrafish spinal cord. Inset: OPCs display short arbors and co-express Sox10. 50 μm cross section; asterisk marks the central canal; scale bar represents 100 μm.
