Motility of Cultured Iridophores from the Freshwater Goby Odontobutis obscura : Cell Biology and Morphology

概要

Iridophores in the integument of the freshwater goby, Odontobutis obscura, are motile. Iridophores isolated from scales of the goby were cultured in L-15 medium. The primary cultured cells were motile. Their movements involved aggregation and dispersion of platelets within the cells, which were not caused by a reversible retraction of cellular processes. Alpha-MSH induced aggregation of platelets, while melatonin and norepinephrine, separately, induced dispersion of the platelets. These responses of the cultured iridophores to drugs were the same with as those of iridophores in preparations of isolated scales. The speed of migration of platelets in cultured iridophores was very slow, and it appeared to be the same as that in iridophores in intact scales. Most of the cultured iridophores exhibited sensitivity to light; they assumed a dispersed state in the light and an aggregated state in darkness.
