Neon-green fluorescence in the desert gecko Pachydactylus rangei caused by iridophores

Scientific Reports, 2021
Biofluorescence is widespread in the natural world, but only recently discovered in terrestrial vertebrates. Here, we report on the discovery of iridophore-based, neon-green flourescence in the gecko Pachydactylus rangei, localised to the skin around the

A Simple Method for RNA-Seq of Manually Isolated Chromatophores in Oryzias Fishes. [PDF]

Dev Growth Differ
ABSTRACT 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 ...

Intermediate filaments spatially organize intracellular nanostructures to produce the bright structural blue of ribbontail stingrays across ontogeny [PDF]

Frontiers in Cell and Developmental Biology
In 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 ...

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

Body Coloration Characterization and Proteomic Analysis of Diurnal Color Variation in Farmed Larimichthys crocea [PDF]

Animals
The large yellow croaker (Larimichthys crocea) is an economically significant aquaculture species in Asia, with skin coloration being a key quality attribute affecting consumer choice and commercial value. This study integrated morphological, biochemical,

Inconspicuous breeding coloration to conceal eggs during mouthbrooding in male cardinalfish [PDF]

iScience
Summary: Animals exhibit colorations optimal for their niche, which hides their existence from other organisms. In Apogoninae fishes, the father broods their egg inside their mouth.

The Early Development of the Blue-Eye Cichlid, Cryptoheros spilurus (Cichliformes: Cichlidae). [PDF]

Evol Dev
We document the early development of Cryptoheros spilurus, highlighting rapid cranial differentiation, sensory organ formation, and fin development. Ontogenetic allometry and ultrastructural traits reveal functional adaptations for early foraging and locomotion, offering insights into ecological success and the developmental basis of cichlid ...

Synergistic Regulation of Pigment Cell Precursors’ Differentiation and Migration by ednrb1a and ednrb2 in Nile Tilapia [PDF]

Cells
The 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 ...

Cell-cell communication as underlying principle governing color pattern formation in teleost fishes [PDF]

Nature Communications
The diverse pigmentation patterns of animals are crucial for predation avoidance and behavioral display. This diversity arises from interactions among distinct pigment cell types, yet mechanisms generating pattern variation across teleost fishes remain ...

Iridophores as a source of robustness in zebrafish stripes and variability in Danio patterns

Nature Communications, 2018
Iridophores interact with other cells to give zebrafish their stripes, but what drives their form shifts is unknown. Here, modelling allows the authors to identify robust cues that may specify iridophore form and to find changes to these cues that likely
