Gene expression analysis of zebrafish melanocytes, iridophores, and retinal pigmented epithelium reveals indicators of biological function and developmental origin. [PDF]
PLoS ONE, 2013 In order to facilitate understanding of pigment cell biology, we developed a method to concomitantly purify melanocytes, iridophores, and retinal pigmented epithelium from zebrafish, and analyzed their transcriptomes. Comparing expression data from these

Intermediate filaments spatially organize intracellular nanostructures to produce the bright structural blue of ribbontail stingrays across ontogeny. [PDF]
Front Cell Dev BiolIn animals, pigments but also nanostructures determine skin coloration, and many shades are produced by combining both mechanisms. Recently, we discovered a new mechanism for blue coloration in the ribbontail stingray Taeniura lymma, a species with ...

A Simple Method for RNA-Seq of Manually Isolated Chromatophores in Oryzias Fishes. [PDF]
Dev Growth DifferABSTRACT RNA sequencing (RNA‐seq) has become an essential tool for analyzing gene expression and exploring cell type–specific transcriptomes. However, sample preparation and quality control remain challenging, as current approaches typically rely on dissecting tissues containing mixed cell populations or using flow cytometry to isolate fluorescently ...

In situ differentiation of iridophore crystallotypes underlies zebrafish stripe patterning [PDF]
Nature Communications, 2020 Skin color patterns are ubiquitous in nature, evolve rapidly, and impact social behavior1, predator avoidance2, and protection from ultraviolet irradiation3. A leading model system for vertebrate skin patterning is the zebrafish4-7; its alternating blue stripes and yellow interstripes depend on guanine crystal-containing cells called iridophores that ...

Pigments, Chromatophore Structure, and Gene Expression Underlying Colour Polytypy of a Panamanian Poison Frog. [PDF]
Mol EcolABSTRACT Colour polytypism represents an example of phenotypic diversification shaped by genetic divergence and ecological pressures. Poison frogs of the genus Oophaga (Dendrobatidae) are highly polytypic in coloration, making them an ideal system for investigating the genetic and physiological basis of colour variation.

Purine Molecular Interactions Determine Anisotropic Shape of Zebrafish Biogenic Crystals. [PDF]
Small MethodsMany organisms self‐organize crystals for vision, pigmentation, or storage. In zebrafish, iridophores produce anisotropic crystals in iridosomes. Using imaging and genetic tools, crystal growth is shown to favor the b‐axis, shaped by guanine‐to‐hypoxanthine ratios and hydrogen bonding resulting thereof.

Reflectin genes and development of iridophore patterns in Sepia officinalis embryos (Mollusca, Cephalopoda) [PDF]
Developmental Dynamics, 2013 Background: In the cuttlefish Sepia officinalis, iridescence is known to play a role in patterning and communication. In iridophores, iridosomes are composed of reflectins, a protein family, which show great diversity in all cephalopod species. Iridosomes are established before hatching, but very little is known about how these cells are established ...

Pigment pattern morphospace of Danio fishes: evolutionary diversification and mutational effects
Biology Open, 2021 Molecular and cellular mechanisms underlying variation in adult form remain largely unknown. Adult pigment patterns of fishes in the genus Danio, which includes zebrafish, Danio rerio, consist of horizontal stripes, vertical bars, spots and uniform ...
