In situ differentiation of iridophore crystallotypes underlies zebrafish stripe patterning [PDF]
Nature Communications, 2020 The skin of zebrafish is patterned by alternating blue stripes and yellow interstripes which arises from guanine crystal-containing cells called iridophores that reflect light.

Endothelin signalling in iridophore development and stripe pattern formation of zebrafish [PDF]
Biology Open, 2014 Colour patterns of adult fish are composed of several different types of pigment cells distributing in the skin during juvenile development. The zebrafish, Danio rerio, displays a striking pattern of dark stripes of melanophores interspersed with light ...

Epigenetic dynamics shaping melanophore and iridophore cell fate in zebrafish [PDF]
Genome Biology, 2021 Background Zebrafish pigment cell differentiation provides an attractive model for studying cell fate progression as a neural crest progenitor engenders diverse cell types, including two morphologically distinct pigment cells: black melanophores and ...

Leukocyte tyrosine kinase functions in pigment cell development. [PDF]
PLoS Genetics, 2008 A fundamental problem in developmental biology concerns how multipotent precursors choose specific fates. Neural crest cells (NCCs) are multipotent, yet the mechanisms driving specific fate choices remain incompletely understood.

Frogs have layers: a comparative histological study of colour polymorphism in Oophaga poison frogs [PDF]
PeerJBackground Colour polymorphism in aposematic species is often associated with ecological divergence and predator selection. In amphibians, colouration is achieved through the chromatophore unit, a layered structure of pigment-containing cells ...

Inconspicuous breeding coloration to conceal eggs during mouthbrooding in male cardinalfish [PDF]
iScienceSummary: Animals exhibit colorations optimal for their niche, which hides their existence from other organisms. In Apogoninae fishes, the father broods their egg inside their mouth.

Functions of thyroid hormone signaling in regulating melanophore, iridophore, erythrophore, and pigment pattern formation in spotted scat (Scatophagus argus) [PDF]
BMC GenomicsBackground Spotted scat, a marine aquaculture fish, has variable body color development stages during their ontogenesis. However, the regulatory mechanism of body color patterns formation was poorly understood.

Genomic diversification between aposematic and cryptic phenotypes of Oophaga granulifera (Anura: Dendrobatidae) [PDF]
Scientific ReportsAposematism and crypsis are contrasting antipredator strategies widespread across animal taxa, yet their genetic basis remains poorly understood in amphibians.

It's not easy being green: Comparing typical skin colouration among amphibians with colour abnormalities associated with chromatophore deficits [PDF]
Ecology and EvolutionAmphibians can obtain their colour from a combination of several different pigment and light reflecting cell types called chromatophores, with defects in one or several of the cells leading to colour abnormalities. There is a need for better recording of

Iridophores as a source of robustness in zebrafish stripes and variability in Danio patterns [PDF]
Nature Communications, 2018 Iridophores interact with other cells to give zebrafish their stripes, but what drives their form shifts is unknown. Here, modelling allows the authors to identify robust cues that may specify iridophore form and to find changes to these cues that likely
