Modeling of pattern regulation in melanophores
Journal of Theoretical Biology, 2007Melanosomes, pigment granules in melanophores, play a principal role in physiological color adaptation of fish and frog. Melanophores regulate melanosome trafficking on cytoskeletal filaments to generate a range of spatiotemporal patterns. Here, we present the first comprehensive model of spatiotemporal evolution of melanosome patterns.

Regulation of pigmentation in zebrafish melanophores
Pigment Cell Research, 2006SummaryIn comparison with the molecular genetics of melanogenesis in mammals, the regulation of pigmentation in poikilothermic vertebrates is poorly understood. Mammals undergo morphological colour change under hormonal control, but strikingly, many lower vertebrates display a rapid physiological colour change in response to the same hormones.

Vimentin intermediate filaments in fish melanophores
Journal of Cell Science, 1987ABSTRACT The distribution and chemical composition of intermediate filaments in cultured melanophores of two teleost species -Gymnocorymbus ternetzi and Pterophyllum scalare -were studied by immunofluorescence staining and immunoblotting techniques.

Biosensing of opioids using frog melanophores
Biosensors and Bioelectronics, 2002Spectacular color changes of fishes, frogs and other lower vertebrates are due to the motile activities of specialized pigment containing cells. Pigment cells are interesting for biosensing purposes since they provide an easily monitored physiological phenomenon.

Exogenous melatonin and melanophore development inXenopus
Experientia, 1978Xenopus larvae raised from stage 21 in melatonin solution and upon a dark background had fewer head melanophores at stage 48 than control animals not exposed to melatonin. Rearing larvae in melatonin solution seems to mimic rearing larvae on a light background.

The action of reserpine on teleost melanophores
European Journal of Pharmacology, 1973Abstract Reserpine caused darkening of both pencil fish and angelfish, this effect lasted for at least 10 and 25 days respectively. The aggregation of pigment granules within the melanophores evoked by stimulation of the nerves supplying the melanophores was inhibited by reserpine in both species.

The cytoskeleton in fish melanophore melanosome positioning
Microscopy Research and Technique, 2002AbstractMelanophore melanosomes organelles can be regulated to move and locate correspondingly to many other different organelle types. Comparing lessons from analysis of a specific melanosome distribution can, therefore, contribute to the understanding of distribution of other organelles, and vice versa.

Melanophore Recombinant Receptor Systems
2000This chapter describes the development and application of a Xenopus laevis melanophore recombinant system to study receptor-ligand interactions. Many Poikilothermie vertebrates possess the ability to change their skin color rapidly. The cells responsible for these variations in appearance are called chromatophores and depending on the animal, a variety

Proliferation of amphibian melanophores in vitro
Developmental Biology, 1974Abstract Melanophores were isolated from the tail skin of bullfrog tadpoles and cultured in vitro . Cell proliferation occurred 3–4 weeks after inoculation and the cells doubled their number about every 5 days to form a colony of uniformly pigmented melanophores.
