EVOLUTION OF THE GCH GENE FAMILY IN VERTEBRATES AND ITS IMPORTANCE FOR XANTHOPHORE
Medaka has four main pigments (melanophore, iridophore, leucophore, and xanthophore
The chromatophores of teleosts are generally classified into seven categories on the basis of their color: melanophore (black), erythrophore (red), xanthophore
(yellow), cyanophore (blue), leucophore (white), iridophore (iridescent color), and erythro-iridophore (reddish violet) (1-4).
Pigment cells (chromophores) are melanophores, similar to melanocytes (black), xanthophores
(yellow), and iridophores (light grey).
Until recently, almost all research on zebrafish stripes focused on the other two pigment cells: the black cells (called melanophores) and the yellow cells (called xanthophores
Mature chromatophores are often grouped by the color of their reflectance under white light: xanthophores
(yellow), erythrophores (red), iridophores (reflective and/or iridescent), leucophores (white), melanophores (black/brown), and cyanophores (blue).
