Fig. 1. Xanthophore countershading in embryonic zebrafish.

(A and B) Lateral views of 3-dpf zebrafish trunks. Red arrowheads indicated the differentiated xanthophores (A). Autofluorescent xanthophores on 3-dpf zebrafish trunks (B). More xanthophores reside at the dorsum than the ventrum. (C) Whole-mount in situ hybridization (WISH) staining at serial stages shows the gch2⁺ xanthoblasts migration begins at 24 hpf and finishes at 30 hpf. (D) Schematic diagram of the xanthoblasts/xanthophores counting region. The horizontal myoseptum is indicated by the black dotted line. (E) Quantification of gch2⁺ xanthophores density in the dorsal and ventral trunks, respectively. n = 9 for each group. Unpaired Student’s t tests were used to calculate the P value. Two-tailed P values are used. Error bars represent means ± SD. ****P < 0.0001. WT, wild type.
