Fig. S3 Xanthoblast marker Pax3/7 expression overlaps with iridoblast and melanoblast marker. (A–I) Confocal images collected from lateral aspect of anterior tail region of fixed zebrafish, 20x. (A–C,J) Wild-type embryo reveals that Pax3/7+ cells overlap with pnp1 expression at 24 hpf then resolve at 50 hpf (D–F). (A,D) Pax3/7 (B,E) pnp1. (C,F) Color merged: red: Pax3/7 antibody, green: pnp1 mRNA (inset 40x). (G–I) Wild-type embryo reveals Pax3/7 signal strongly localized with mitfa:gfp expression at 24 hpf (G) Pax3/7 (H) mitfa:gfp. (I) Color merged: green: mitfa:gfp, red: Pax3/7 (inset 40x). (J,K) Line graphs depicting percent of overlap between chromatoblast markers (see Table S1 in supplementary material). (J) Red line = % of Pax3/7+ cells that are pnp4a+/Pax3/7+. Green line = % of pnp4a+ cells that are pnp4a+/Pax3/7+. (K) Red line = % of Pax3/7+ cells that are mitfa:gfp+/Pax3/7+. Green line = % of mitfa:gfp+ cells that are mitfa:gfp+/Pax3/7+. Scale bars: (A–I) 20 μm; (C,F,I inset) 10 μm.
