Ultrastructure of the dermal chromatophores in the Fringe-toed lizard, Acanthodactylus orientalis

open access: yesZoologia (Curitiba), 2017
Histology and electron microscopic studies of the dorsal skin of the Fringe-toed lizard, Acanthodactylus orientalis Angel, 1936, showed three types of dermal chromatophores: xanthophores, iridophores and melanophores. These pigment cells were observed in

Redefinition of Stemonosudis intermedia (Ege, 1933) and description of a new species from the western Atlantic Ocean (Aulopiformes: Paralepididae)

open access: yesJournal of Fish Biology, Volume 108, Issue 5, Page 1582-1598, May 2026.
Abstract We examined specimens of slender barracudina in the genus Stemonosudis collected from the western Atlantic Ocean. Investigation revealed that seven specimens represent the first adult records of Stemonosudis intermedia (Ege, 1933), previously known only from juveniles. We redescribed S.

Melanophore-Stimulating Substances in Amphibia

open access: yes, 1963
A study of the Northwestern tiger salamander, Ambystoma tigrinum melanostictum (Baird), has confirmed a study of the Pacific tree frog, Hyla regilla, that a melanophore-stimulating substance is produced in the infundibulum of the embryo and young larva ...

Development of Digital Techniques for Analysis of Hormone Regulation of Melanophore Activity in Red Drum [PDF]

open access: yes, 2008
Melanophores are pigment bearing cells, which have been used as a practical method to demonstrate mechanisms of hormone interaction. A current teaching laboratory has been restructured in order to increase student participation, provide tangible results,

Melanophore integrity mutants show melanophore and iridophore defects.

open access: yes, 2013
A, B) Dorsal, head images of live wildtype and mutant siblings, 5dpf. Wildtype melanophores maintain dark pigmentation and are now interacting with silver iridescent iridophores (present on eyes and in the center of caudal melanophore patch).

A chemical genomic approach identifies matrix metalloptroteinases as playing an essential and specific role in Xenopus melanophore migration

open access: yes, 2009
SummaryTo dissect the function of matrix metalloproteinases (MMPs) involved in cellular migration in vivo, we undertook both a forward chemical genomic screen and a functional approach to discover modulators of melanophore (pigment cell) migration in ...

Morphological Development and DNA Barcoding Identification of Pholis fangi Larvae and Juveniles in the Yellow Sea

open access: yesFishes
Pholis fangi is a small, bottom-dwelling fish species endemic to the Yellow Sea and Bohai Sea in China. While previous research has focused on its population biology and molecular structure, little is known about the early developmental stages of this ...

Melanophore loss in vps11w66 mutants is due to a caspase-independent mechanism.

open access: yes, 2013
A−C) Dorsal or lateral head images of 2dpf kitw34 control (A, B) or zVAD-fmk (C) treated larvae, beginning at 1dpf. Red asterisks indicate regions of changes in melanophore morphology and number suggesting rescue following zVAD-fmk treatment ...

Study on the Mechanisms for Melanophore Contraction in Otocinclus

open access: yes, 2019
Otocinclus is a very popular catfish, belonging to the order Siluriformes, family Loricariidae. Otocinclus has a very flat dorsal surface and the melanophores in the dorsal dermal skin are distributed in a proper density that allows us to recognize and ...

Iridophores influenced melanophore pattern in xanthophore-deficient csf1r mutants.

open access: yes, 2013
(A,B) In stage-matched siblings treated with Mtz, a region on the tail from which iridophores have been ablated (dashed yellow lines in B) exhibits more melanophores than the corresponding region of the control larva (shown here at ∼8.5 SSL). Both larvae
