Protein Kinase A Signaling Inhibits Iridophore Differentiation in Zebrafish [PDF]
Journal of Developmental Biology, 2018 In zebrafish (Danio rerio), iridophores are specified from neural crest cells and represent a tractable system for examining mechanisms of cell fate and differentiation.

pnp4a Is the Causal Gene of the Medaka Iridophore Mutant guanineless [PDF]
G3: Genes, Genomes, Genetics, 2017 See-through medaka lines are suitable for observing internal organs throughout life. They were bred by crossing multiple color mutants. However, some of the causal genes for these mutants have not been identified.

Asymmetric Functional Divergence of alx4a and alx4b in Iridophore Differentiation and Cranial Development in Nile Tilapia [PDF]
CellsNeural crest cells give rise to the craniofacial skeleton and multiple pigment cell lineages, yet how duplicated developmental regulators partition their ancestral functions after teleost-specific whole-genome duplication remains unclear.

Partial Replacement of Fish Meal with Fish Scale Meal Enhances Body Color Brightness and Iridophore Development in Koi (Cyprinus carpio var. koi) [PDF]
AnimalsBody color brightness is a key determinant of ornamental value in koi, yet nutritional strategies targeting structural coloration mediated by iridophores remain underexplored.

A systems biology approach uncovers the core gene regulatory network governing iridophore fate choice from the neural crest [PDF]
PLoS Genetics, 2018 Multipotent neural crest (NC) progenitors generate an astonishing array of derivatives, including neuronal, skeletal components and pigment cells (chromatophores), but the molecular mechanisms allowing balanced selection of each fate remain unknown.

Biology Open, 2013 Summary In the skin of adult zebrafish, three pigment cell types arrange into alternating horizontal stripes, melanophores in dark stripes, xanthophores in light interstripes and iridophores in both stripes and interstripes.

Synergistic Regulation of Pigment Cell Precursors’ Differentiation and Migration by ednrb1a and ednrb2 in Nile Tilapia [PDF]
CellsThe evolutionary loss of ednrb2 in specific vertebrate lineages, such as mammals and cypriniform fish, raises fundamental questions about its functional necessity and potential redundancy or synergy with paralogous endothelin receptors in pigment cell ...

Iridophore apoptosis mediates socially-regulated developmental color pattern plasticity in an anemonefish. [PDF]
PLoS BiologyUnderstanding the developmental basis of phenotypic plasticity is key to unraveling the origins of biodiversity. In coral reef fishes, color pattern changes during ontogeny can serve adaptive functions, yet the mechanisms and ecological contexts shaping ...

Colour Confusion: Reviewing Ambiguities in the Identification and Classification of Chromatophore Deficiencies Among Amphibians [PDF]
Ecology and EvolutionThe colour of amphibian skin and eyes (retina and iris) is the result of light interacting with cells called chromatophores, primarily xanthophores, iridophores and melanophores, that can be found in various combinations.
