Signaling for color change in melanophores [Elektronisk resurs] : and a biosensor application

open access: yes, 2001
Melanophores are dark brown pigment cells located in the skin of fish, amphibia, reptiles, and many invertebrates. The color of the animal can change via rearrangement of pigment granules, melanosomes, in the cells.

The Action of Ephedrine on Melanophores.

open access: yesExperimental Biology and Medicine, 1930
Nadler1 found that in the squid, Loligo pealii, ephedrine injected subcutaneously, produced a local blanching which was considered as due to an inhibition of the smooth muscle of the chromatophore system and a generalized reddish coloration ascribed to a stimulation of the central nervous system.

Localization and characterization of adrenergic receptors on frog skin melanophores

open access: yes, 1981
The functional location of adrenergic binding sites was studied in frog skin melanophores by injecting norepinephrine (NE) outside and inside a melanophore.

When Neural Crest and Placodes Collide: Interactions between Melanophores and the Lateral Lines That Generate Stripes in the SalamanderAmbystoma tigrinum tigrinum(Ambystomatidae)

open access: yes, 1996
A prominent element of the early larval pigment pattern in the salamanderAmbystoma tigrinum tigrinum(family Ambystomatidae) is a horizontal stripe over the lateral surface of the myotomes where otherwise abundant, neural crest-derived melanophores are ...

On the nervous and hormonal control of melanophores and their differential reactions in the catfish Ictalurus melas (Raffinesque)

open access: yes, 1971
The melanophores in the catfish I. melas are arranged in 3 layers, one epidermal and two dermal. The former are the smallest, and also differ from those in the dermis in their shape and in their reaction-times in response to background change ...

Noradrenaline- and melatonin-mediated regulation of pigment aggregation in fish melanophores

open access: yes, 2003
The effects of melatonin and noradrenaline (NA) on bi-directional melanosome transport were analysed in primary cultures of melanophores from the Atlantic cod.
