Microtubule system of isolated fish melanophores as revealed by immunofluorescence microscopy. 1978

M Schliwa, and M Osborn, and K Weber

The microtubule system of melanophores of the angelfish, Pterophyllum scalare, has been studied using antibodies prepared against purified porcine brain tubulin in indirect immunofluorescence microscopy. Melanophores were freed from the surrounding tissue components of isolated scales by mild enzymatic digestion and then allowed to settle on a glass cover slip. In both the dispersed and the aggregated states large numbers of fluorescent fibers are seen. The number and the astral arrangement of these fibers, which run from the central region to the periphery of the cell, are striking. The system of fluorescent fibers is replaced by diffuse fluorescence of moderate intensity after cold treatment, but is restored after rewarming the cells. Differences in the immunofluorescence profiles between cells with dispersed and aggregated pigment are discussed in relation to electron microscopic data available for this system.

UI	MeSH Term	Description	Entries
D008547	Melanophores	Chromatophores (large pigment cells of fish, amphibia, reptiles and many invertebrates) which contain melanin. Short term color changes are brought about by an active redistribution of the melanophores pigment containing organelles (MELANOSOMES). Mammals do not have melanophores; however they have retained smaller pigment cells known as MELANOCYTES.	Melanophore
D008858	Microscopy, Phase-Contrast	A form of interference microscopy in which variations of the refracting index in the object are converted into variations of intensity in the image. This is achieved by the action of a phase plate.	Phase-Contrast Microscopy,Microscopies, Phase-Contrast,Microscopy, Phase Contrast,Phase Contrast Microscopy,Phase-Contrast Microscopies
D008870	Microtubules	Slender, cylindrical filaments found in the cytoskeleton of plant and animal cells. They are composed of the protein TUBULIN and are influenced by TUBULIN MODULATORS.	Microtubule
D010860	Pigments, Biological	Any normal or abnormal coloring matter in PLANTS; ANIMALS or micro-organisms.	Biological Pigments
D005399	Fishes	A group of cold-blooded, aquatic vertebrates having gills, fins, a cartilaginous or bony endoskeleton, and elongated bodies covered with scales.
D005455	Fluorescent Antibody Technique	Test for tissue antigen using either a direct method, by conjugation of antibody with fluorescent dye (FLUORESCENT ANTIBODY TECHNIQUE, DIRECT) or an indirect method, by formation of antigen-antibody complex which is then labeled with fluorescein-conjugated anti-immunoglobulin antibody (FLUORESCENT ANTIBODY TECHNIQUE, INDIRECT). The tissue is then examined by fluorescence microscopy.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D012867	Skin	The outer covering of the body that protects it from the environment. It is composed of the DERMIS and the EPIDERMIS.
