...Erine H. Budi; Larissa B. Patterson; David M. Parichy Vertebrate pigment cells are derived from neural crest cells and are a useful system for studying neural crest-derived traits during post-embryonic development. In zebrafish, neural crest-derived melanophores differentiate during embryogenesis...

..., the zebrafish D. rerio , is a model organism for biomedical research. Previous studies have shown that in zebrafish, stripes form by migration and differentiation of distinct populations of melanophores:early metamorphic (EM) melanophores arise widely dispersed and then migrate into stripes, whereas late...

... crest derivatives. Embryos mutant for choker manifest a unique pigment pattern phenotype that combines a loss of lateral stripe melanophores with an ectopic melanophore `collar' at the head-trunk border. We find that defects in neural crest migration are largely restricted to the lateral migration...

... expressed by Danio fishes. These patterns result from several classes of pigment cells including black melanophores and yellow xanthophores, which differentiate during metamorphosis from latent stem cells of presumptive neural crest origin. In the zebrafish D. rerio ,alternating light and dark horizontal...

...Florian Maderspacher; Christiane Nüsslein-Volhard Colour patterns are a prominent feature of many animals and are of high evolutionary relevance. In zebrafish, the adult pigment pattern comprises alternating stripes of two pigment cell types, melanophores and xanthophores. How the stripes...

... , alternating horizontal stripes of black melanophores and yellow xanthophores are a prominent feature of the adult pigment pattern. In fms mutant zebrafish, however, xanthophores fail to develop and melanophore stripes are severely disrupted. fms encodes a type III receptor tyrosine kinase expressed...

... fertilisation. We provide evidence that melanophore defects in colourless mutants can be largely explained by disruption of nacre/mitf expression. We propose that all defects of affected crest derivatives are consistent with a primary role for colourless/sox10 in specification of non-ectomesenchymal crest...

Unpigmented melanophores from albino axolotls are illustrated for the first time, and in larval albino axolotls...
