THE DERMAL CHROMATOPHORE UNIT [PDF]

open access: yesJournal of Cell Biology, 1968
Rapid color changes of amphibians are mediated by three types of dermal chromatophores, xanthophores, iridophores, and melanophores, which comprise a morphologically and physiologically distinct structure, the dermal chromatophore unit. Xanthophores, the outermost element, are located immediately below the basal lamella.

THE CHARACTER OF CHROMATOPHORES. [PDF]

open access: yesJAMA: The Journal of the American Medical Association, 1904
In regard to the origin of the cell masses characteristic of pigmented moles and in regard to the origin of the melanotic tumors of the skin, different views are still held. A number of pathologists believe in the epithelial origin of nevi and of melanotic tumors; others assume a mesodermal origin.

THE CHROMATOPHORAL NEUROHUMORS OF THE DOGFISH [PDF]

open access: yesJournal of General Physiology, 1935
1. The common dogfish, Mustelus canis, as is well known, exhibits two temporary extremes of tint, one dark, the other light. The dark phase is induced by a secretion from the pituitary gland which is carried in the blood, hence a substance soluble in water (a hydroneurohumor).

Photosensitivity of Chromatophores [PDF]

open access: yesAmerican Zoologist, 1983
Almost all major phyla of invertebrates and lower vertebrates display a direct sensitivity of their chromatophores to light by either dispersing or—in rare cases—aggregating the pigment granules within the cell. This “primary response” of color change is an accessory component of the “dermal light sense” and characterizes the chromatophores as an ...

Absorption Changes in Bacterial Chromatophores

open access: yesBiophysical Journal, 1964
The magnitude and kinetics of photo-induced absorption changes in bacterial chromatophores (R. rubrum, R. spheroides and Chromatium) have been studied as a function of potential, established by added redox couples. No photochanges can be observed above +0.55 v or below -0.15 v.

The architecture of Rhodobacter sphaeroides chromatophores

open access: yesBiochimica et Biophysica Acta (BBA) - Bioenergetics, 2014
The chromatophores of Rhodobacter (Rb.) sphaeroides represent a minimal bio-energetic system, which efficiently converts light energy into usable chemical energy. Despite extensive studies, several issues pertaining to the morphology and molecular architecture of this elemental energy conversion system remain controversial or unknown.
