Fishing for iridophores, catching an oncogene
, 2004 We have a growing understanding of how the neural crest generates melanocytes, but little idea how the other distinct types of pigment cells characteristic of poikilothermic vertebrates are formed.

Semi‐automated MicroED system unveils multiple polymorphs in fish‐derived guanine crystals
Acta Crystallographica Section C, Volume 82, Issue 7, Page 310-323, July 2026.A semi‐automated MicroED data collection and processing system was established and shown to be suitable for the structural investigation of submicrometer‐scale biogenic crystals.Certain fish display silvery or blue colour, not through pigments, but through specialized guanine crystals that exist within iridophore cells in their skin. Within these cells,

Iridophores influenced melanophore pattern in xanthophore-deficient csf1r mutants.
, 2013 (A,B) In stage-matched siblings treated with Mtz, a region on the tail from which iridophores have been ablated (dashed yellow lines in B) exhibits more melanophores than the corresponding region of the control larva (shown here at ∼8.5 SSL). Both larvae

Genetics of white color and iridophoroma in "Lemon Frost" leopard geckos.
PLoS Genetics, 2021 The squamates (lizards and snakes) are close relatives of birds and mammals, with more than 10,000 described species that display extensive variation in a number of important biological traits, including coloration, venom production, and regeneration ...

Shifty Frogs: Evidence of Iridescence Among Amphibians
Austral Ecology, Volume 51, Issue 7, July 2026.ABSTRACT Iridescence is a striking optical phenomenon observed in some animals whereby colour or reflectivity changes based on viewing angle, such that two observers in different locations may simultaneously perceive the same tissue differently. Among amphibians, there is limited photographic evidence of tissues displaying colour shifts that define ...

Bar, stripe and spot development in sand-dwelling cichlids from Lake Malawi
EvoDevo, 2019 Background Melanic patterns such as horizontal stripes, vertical bars and spots are common among teleost fishes and often serve roles in camouflage or mimicry. Extensive research in the zebrafish model has shown that the development of horizontal stripes

The guanine synthesis cycle is highly enriched in iridophores.
, 2013 Shown is a model for guanine production based on transcriptome data as given in Table 6. Genes that are statistically enriched compared to melanocytes are shown in bold, those not statistically different are in normal font.

Evolutionary Applications, Volume 19, Issue 7, July 2026.ABSTRACT The leopard coral grouper, Plectropomus leopardus Lacepède, 1802, is an ecologically and economically important species in the family Epinephelidae. However, the absence of a complete reference genome has impeded advanced genetic research on this species, and the phylogenetic position of Epinephelidae within Perciformes remains unresolved ...

Nature Communications, 2016 Melanophores, iridophores and xanthophores are pigment-cell types that interact to form the stripes in zebrafish. Here, the authors study the interaction between cells of the same kind and show that each pigment-cell type covers the skin by contact based

Ablation of iridophores by Mtz treatment of fish injected with pnp4a:NTR.
, 2013 (A) Iridophores in a wild-type larva (6.5 SSL) were marked by Venus fluorescence following injection of pnp4a:nlsVenus-V2a-NTR plasmid as the 1-cell stage, as shown in bright-field (A), fluorescence (A′) and merged (A″) views.
