Fig. 1
Peripheral and central myelinating glia are segregated at the MEP. A: Schematic of a zebrafish larvae with the brain and spinal cord labeled in red. Boxed region shows the spinal motor nerve roots, which are magnified in B. B: Schematics of spinal motor roots at 24, 48, and 72 hpf showing motor axons (red), PNS glia (green) and CNS glia (yellow). Images of Tg(sox10:eos);Tg(olig2:dsred) embryos at (C) 24, (D) 48 (E), and 72 hpf. Lateral and cross section (90°) views are shown. Arrows denote peripheral sox10+ glia and arrowheads denote central sox10+/olig2+ OPCs. Asterisks at 48 and 72 hpf denote Eos expression in spinal cord neurons. Dotted lines represents spinal cord boundary. Scale bar, 25 µm. |
