Homotypic cell competition regulates proliferation and tiling of zebrafish pigment cells during colour pattern formation

open access: yesNature 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

Identification of kit-ligand a as the Gene Responsible for the Medaka Pigment Cell Mutant few melanophore

open access: yesG3: Genes, Genomes, Genetics, 2020
The body coloration of animals is due to pigment cells derived from neural crest cells, which are multipotent and differentiate into diverse cell types.

Hierarchical Assembly as a Design Principle: Structure–Property Relationships Linking Biological Architectures to Functional Aggregate Materials

open access: yesAggregate, Volume 7, Issue 9, September 2026.
Biological function arises from aggregates rather than from molecules. Comparing biomimetic systems on a common basis reveals three transferable design rules governing hierarchical assembly, interfacial gradients, and stimulus‐coupled anisotropy, and identifies self‐healing and single‐step multiscale integration as properties that do not transfer to ...

transparent, a gene affecting stripe formation in Zebrafish, encodes the mitochondrial protein Mpv17 that is required for iridophore survival

open access: yesBiology 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.

Beyond the Classics: The Synergy of AI and Genomics Reveals an Expanded Repertoire of Pigmentation Genes

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 346, Issue 6, Page 475-486, September 2026.
Classical approaches for coloration analysis are limited by human low‐resolution phenotyping and genetic analysis. Artificial intelligence allows us to find genes beyond the tip of the iceberg that explain color and pattern diversity in nature. ABSTRACT Pigmentation has long served as a powerful system for exploring gene–trait relationships, yet much ...

Ultrastructural and biochemical analysis of epidermal xanthophores and dermal chromatophores of the teleost Sparus aurata [PDF]

open access: yes, 1999
We have studied the pigmentary system of the teleost Sparus aurata skin by electron microscopy and chromatographic analysis. Under electron microscopy, we found the dermis to contain the three major types of recognized chromatophores: melanophores ...

Shifty Frogs: Evidence of Iridescence Among Amphibians

open access: yesAustral 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 ...

External appearance and chromatophores analysis in the four color phenotypes.

open access: yes, 2020
A: Lateral view of wild-type, cobalt blue, yellow-albino, and white-albino female adults of rainbow trout. Chromatophores in bright field (left inferior) and under fluorescence (right inferior; xanthophores emit green auto fluorescence); the region ...

Comparison of Human Melanoma Single Cell Profiles to Evolutionary Medicine Model Xiphophorus Provides Insights in Disease Control

open access: yesPigment Cell &Melanoma Research, Volume 39, Issue 4, July 2026.
Single‐nucleus RNA sequencing analysis of Xiphophorus melanoma, an evolutionary medicine model, revealed cellular heterogeneity that closely mirrors that of human melanoma. Immune and tumor cell subtyping identified an immune‐evasive tumor microenvironment. This melanoma cell atlas provides a framework for investigating conserved cellular and molecular
