Amoeboid Movements of Chromatophores

High-Speed Imaging of Amoeboid Movements Using Light-Sheet Microscopy

Light-sheet microscopy has been developed as a powerful tool for live imaging in biological studies. The efficient illumination of specimens using light-sheet microscopy makes it highly amenable to high-speed imaging. We therefore applied this technology to the observation of amoeboid movements, which are too rapid to capture with conventional microscopy. To simplify the setup of the optical sy...

Cytomatrix in chromatophores

Although intracellular transport is a fascinating and vital function shared by diverse cell systems, our understanding of the processes involved remains incomplete, despite the enormous amount of attention it has received over the past 40 years (46). Recent work on pigment granule transport in chromatophores (e .g ., erythrophores, melanophores, and xanthophores), however, has begun to yield ne...

Electron microscopy of chromatophores of Rhodopseudomonas spheroides.

Gibson, K. D. (St. Mary's Hospital Medical School, London, England). Electron microscopy of Rhodopseudomonas spheroides. J. Bacteriol. 90:1059-1072. 1965.-Fixed and stained chromatophores and whole cells of anaerobically grown Rhodopseudomonas spheroides were examined in thin sections in the electron microscope. Both purified chromatophores and intracellular membrane-bound vesicles had exactly ...

Nervous Control of Chromatophores in Teleost Fishes

Changes ot skin colour with temperature are remarkably consistent in reptiles; high temperatures cause paling of the skin while low temperatures induce darkening. The same rule generally applies to the Amphibia (Parker, 1948), although exceptions have frequently been noted. But in teleost fishes the responses are often ill-defined, unpredictable and even contradictory. There is a large literatu...
