Fig. 4. DRG sensory neurons persist in sox10 embryos without differentiated glial support. Double immunofluorescent detection of DRG neurons (Hu, red) and glia (GFP, green) in 5 dpf embryos showing two examples of sox10 mutant DRG neuron clusters (arrowheads) lacking intimate association with GFP⁺ cells (A,B), contrasting with consistently intimate arrangement with satellite cells in wild types (C). Scale bar: 20 µm.
