Ultrastructure of the skin melanophores and iridophores in paddlefish, Polyodon spathula
Micron, 2007The ultrastructure of melanophores and iridophores of Polyodon spathula has been examined by transmission electron microscopy. In the skin, two types of chromatophores, melanophores and iridophores were founded. Melanophores were localized both in epidermis and dermis.

Zebrafish Leucocyte tyrosine kinase controls iridophore establishment, proliferation and survival
Pigment Cell and Melanoma Research, 2016Summary The zebrafish striped pattern results from the interplay among three pigment cell types; black melanophores, yellow xanthophores and silvery iridophores, making it a valuable model to study pattern formation in vivo.

The Iridophores of the Echinoid Diadema antillarum
Journal of Cell Science, 1961ABSTRACT The blue pattern seen when the skin of Diadema antillarum is viewed by reflected light is due to iridophores. The quality of their blueness varies with the background provided by neighbouring chromatophores. Microdissection reveals that they consist of gelatinous plates contained in a fibrous and cellular capsule.

ACTION SPECTRA FOR THE IRIDOPHORE LIGHT RESPONSE IN THE NEON TETRA
Photochemistry and Photobiology, 1984Abstract The iridophores of some fishes such as the neon tetra (Paracheirodon innesi) are composed of alternating layers of guanine and cytoplasm. In the dark adapted state, the guanine layers are close together and reflect violet light. After illumination these layers separate and the iridophores reflect green light.

Neural Control of Motile Activity of Light‐Sensitive Iridophores in the Neon Tetra
Pigment Cell Research, 1989Experiments with skin pieces revealed that the sympathetic nervous system controls the activity of the light‐sensitive iridophores in the stripes of the neon tetra. The spectral peak reflected from the cells was shifted toward longer wavelengths as a result of a direct interaction between norepinephrine and alpha‐adrenoceptors present on the cell ...

Study of the motile mechanism in neon tetra (Paracheirodon innesi) iridophores
Comparative Biochemistry and Physiology Part A: Physiology, 1992Abstract 1. 1. Using the preparations of lateral stripe skin, the motile mechanism of the neon tetra ( Paracheirodon innesi ) iridophores was studied. 2. 2. Colchicine and vinblastine, antimitotic reagents, inhibited the iridophore response to norepinephrine (NE) reversibly. 3. 3.

Effects of ACTH on melanophores and iridophores isolated from bullfrog tadpoles
General and Comparative Endocrinology, 1973Melanophores and iridophores were isolated from bullfrog tadpoles by the methods of trypsin digestion and Ficoll density-gradient centrifugation and cultured in vitro in collagen-coated plastic dishes. Both chromatophores attached to the dish and formed dendritic structures.

Chemical characterization of reflecting platelets in motile iridophores of blue damselfish
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1989Abstract 1. 1. The chemical nature of the very thin reflecting platelets within the motile iridophores of the blue damselfish, Chrysiptera cyanea , was studied by thin-layer chromatography on crystalline cellulose. 2. 2. The platelets are composed exclusively of guanine, as judged by the limits of sensitivity of this method. 3. 3.
