Molecules, 2020 Aquaculture represents a major part of the world’s food supply. This area of food production is developing rapidly, and as such the tools and analytical techniques used to monitor and assess the quality of fish need to also develop and improve.

Developmental Dynamics, EarlyView.Abstract Neural crest cells are a transient cell population that emerges from the dorsal neural tube during neurulation and migrates extensively throughout the embryo. Among their diverse derivatives, glial cells (such as Schwann and satellite ganglionic cells) and melanocytes represent two major lineages. In vitro studies suggested they share a common

Cells, 2021 Zebrafish has emerged as a powerful model in studies dealing with pigment development and pathobiology of pigment diseases. Due to its conserved pigment pattern with established genetic background, the zebrafish is used for screening of active compounds ...

Investigating the role of alx4a in zebrafish iridophore development
, 2022 The cells that give rise to melanoma, melanocytes, originate from a pluripotent population of embryonic cells called the neural crest (NC). During embryogenesis, neural crest cells undergo an epithelial to mesenchymal transition (EMT) allowing them to ...

A quantitative modelling approach to zebrafish pigment pattern formation
eLife, 2020 Pattern formation is a key aspect of development. Adult zebrafish exhibit a striking striped pattern generated through the self-organisation of three different chromatophores.

Developmental Dynamics, EarlyView.Abstract Background Transcription factors of the MIT/TFE family—mitfa, mitfb, and tfec—play essential roles in specifying pigment cells derived from neural crest cells in vertebrates. In teleosts, which possess multiple pigment cell types, these factors exhibit partially redundant but largely distinct functions across different pigment lineages.

Changes in spectral reflexions from the iridophores of the neon tetra. [PDF]
The Journal of Physiology, 1982 1. The iridescent stripe of the freshwater teleost, the neon tetra, changes from green in the daytime to violet‐blue at night. 2. Spectral reflectance measurements were used to follow these colour changes. 3. Light causes a shift in reflectance to longer wavelengths in living fish and in isolated tissue from the lateral stripe.

Eye Darkening Under Dehydration Stress in the Neotropical Frog Boana punctata (Schneider, 1799)
Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 345, Issue 8, Page 887-893, October 2026.Dehydration induces a strong and partially reversible increase in iris pigmentation in the Neotropical frog Boana punctata. The tight relationship between iris darkening and hydration state identifies ocular pigmentation as a simple, non‐invasive physiological biomarker with broad potential for assessing hydric stress in amphibian populations ...

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
