Figure 8—figure supplement 2. Csf1 requirements for xanthophore pigmentation.

Fish that were wild-type (n = 23), homozygous mutant for csf1a (n = 15), csf1b (n = 9), or both csf1a and csf1b (n = 10) were examined 4–12 wk post-fertilization, with representative phenotypes at 6 wk shown here. csf1a mutants had disrupted patterns and reduced xanthophore pigmentation in fins, whereas csf1b mutants had fewer pigmented xanthophores in the hypodermis and on scales, deficiencies especially apparent on the dorsum of the fish. Fish doubly mutant for both Csf1 loci lacked virtually all xanthophores and resembled csf1ra mutants (Parichy and Turner, 2003).
