Melanophores inside Frogs

open access: yesInternational Letters of Natural Sciences, 2018
Melanocytes/melanophores were known for some decades as pigment cells in skin. The origin of these cells in embryogenesis from neural crest cells is actively investigated now. Some melanocytes/melanophores were described inside adult vertebrates. Historically, these internal melanocytes have been largely ignored, until recently.

Melanophore a2-Adrenoceptors

open access: yes, 1993
The present study provides new insight into the pharmacology, the signal transduction mechanisms and the molecular biology of a2-adrenoceptors (a2-ARs) in black pigment cells (melanophores) of a teleost fish, the cuckoo wrasse (Labrus ossifagus L ...

Magnetic field effect on melanophores of the European whitefish Coregonus lavaretus (Linnaeus, 1758) and vendace Coregonus albula (Linnaeus, 1758) (Salmonidae) during early embryogenesis

open access: yesThe European Zoological Journal, 2017
The effects of a magnetic field (1, 3 and 5 mT), applied during short- (1, 3, 5, 30 and 60 minutes) and long-term (from the beginning of embryogenesis) exposure, on melanophores of the European whitefish, Coregonus lavaretus and vendace, Coregonus albula,

Post-embryonic nerve-associated precursors to adult pigment cells: genetic requirements and dynamics of morphogenesis and differentiation.

open access: yesPLoS Genetics, 2011
The pigment cells of vertebrates serve a variety of functions and generate a stunning variety of patterns. These cells are also implicated in human pathologies including melanoma.

The effect of static magnetic field on melanophores in the sea trout (Salmo trutta m. trutta Linnaeus, 1758) embryos and larvae

open access: yesItalian Journal of Animal Science, 2019
Magnetic field affects many living organisms, fishes included. The fish reactions are observed from the early stage of development, during embryogenesis and larval period, and into adult stage.

Melanophore migration and survival during zebrafish adult pigment stripe development require the immunoglobulin superfamily adhesion molecule Igsf11.

open access: yesPLoS Genetics, 2012
The zebrafish adult pigment pattern has emerged as a useful model for understanding the development and evolution of adult form as well as pattern-forming mechanisms more generally.

EFFECT OF MELANOPHORE-STIMULATING HORMONE ON HUMAN DARK ADAPTATION

open access: yes, 1959
A preparation of melanophore-stimulating hormone (MSH) obtained from porcine anterior pituitary glands was found to produce no effect on the course of dark adaptation in normal human subjects, when injected subcutaneously in doses of 185 or 550 I.U.A ...

Melanophore sensitivity and pigmentation in fish exposed to medetomidine

open access: yes, 2007
Pigment containing cells, melanophores, are abundant in scales and eyes of many fish species. The mobile pigment granules within these cells can be aggregated to give a pale appearance, or dispersed to give a dark appearance.
