Heterotypic interactions regulate cell shape and density during color pattern formation in zebrafish
Biology Open, 2016 The conspicuous striped coloration of zebrafish is produced by cell-cell interactions among three different types of chromatophores: black melanophores, orange/yellow xanthophores and silvery/blue iridophores.

Stress‐induced changes in color expression mediated by iridophores in a polymorphic lizard [PDF]
Ecology and Evolution, 2017 AbstractStress is an important potential factor mediating a broad range of cellular pathways, including those involved in condition‐dependent (i.e., honest) color signal expression. However, the cellular mechanisms underlying the relationship between stress and color expression are largely unknown.

Dynamic colour change predicts movement behaviour in a diadromous fish
Journal of Fish Biology, Volume 108, Issue 6, Page 2205-2210, June 2026.Abstract Dynamic changes in colour and pattern facilitate key behavioural functions in animals, particularly camouflage for predator avoidance. However, the benefits of colour change depend on the environmental and behavioural contexts. We tested how colour change interacts with movement behaviour in a freshwater fish by filming individuals in an open ...

The FASEB Journal, Volume 40, Issue 10, 31 May 2026.This study investigates the role of the vision gene RGR using novel dual knockout zebrafish models. The loss of rgra and rgrb results in zebrafish larvae having reduced visual function and altered retinoid profiles under light but not dark conditions. The OKR phenotype is enhanced under higher light intensities.

Mathematical modelling and refinement of the preliminary iridophore GRN.
, 2018 Graphical representation, simulation outputs and PCA of Monte Carlo results for models A1 (A,D,G), A2 (B,E,H) and A3 (C,F,I)). In the schematics (A-C), green rectangular nodes are used for transcription factor-coding genes, blue rectangles for ...

Advanced Functional Materials, Volume 36, Issue 38, 11 May 2026.Cephalopod‐inspired photonic microparticles with dynamic structural coloration are fabricated via confined self‐assembly of linear block copolymers into ellipsoids containing stacked lamellae. Embedded superparamagnetic nanoparticles enable rapid magnetic alignment, restoring vivid, angle‐dependent color.

DERMAL IRIDOPHORES IN SNAKES; CORRELATIONS WITH HABITAT ADAPTATION AND PHYLOGENY
, 1981 Deep continuous layers of iridophores were discovered in certain Asian Agkistrodon species. A survey of available snakes showed the banded iridophores to be present in North American Crotalus and Sistrurus also, indicating an unreported morphology to be ...

Reduced iridophore proliferation in edn3b mutant D. rerio and D. nigrofasciatus.
, 2018 (A) Among loosely organized iridophores of prospective stripe regions, the percent of individual cells dividing during time-lapse imaging (15 h total duration) was greatest in edn3/+ (wt) D. rerio and markedly reduced in sibling edn3b mutant D.
