Physiological color change in squid iridophores

Cell and Tissue Research, 1990
Evidence is presented that changes in the optical properties of active iridophores in the dermis of the squid Lolliguncula brevis are the result of changes in the ultrastructure of these cells. At least two mechanisms may be involved when active cells change from non-iridescent to iridescent or change iridescent color.

Electrowetting-controlled bio-inspired artificial iridophores

SPIE Proceedings, 2011
Many marine organisms have evolved complex optical mechanisms of dynamic skin color control that allow them to drastically change their visual appearance. In particular, cephalopods have developed especially effective dynamic color control mechanism based on the mechanical actuation of the micro-scale optical structures, which produce either ...

Stimulation of Cultured Iridophores by Amphibian Ventral Conditioned Medium

Pigment Cell Research, 1990
That the ventral integument of adult frogs (Rana pipiens) contains factor(s) that stimulate iridophore expression (adhesion, morphologic appearance, proliferation) was demonstrated on iridophores derived from tadpoles of R. pipiens and Pachymedusa dacnicolor, and maintained in primary culture in a growth medium based upon Leibovitz's L‐15.

Transformation of amphibian iridophores into melanophores in clonal culture

Developmental Biology, 1976
Abstract Iridophores isolated from bullfrog tadpoles were successfully cloned. In primary culture, the iridophores showed contraction of cell bodies by the addition of alkali-treated ACTH. The disappearance of reflecting platelets occurred in proliferating iridophores and many small black melanin granules were synthesized in the cells.
