develops from start stage end stage xantholeucophore ZDB-PUB-190912-11 mentions that on the 8th day of development Yellow EL xanthophores gradually fade from view, entering a cryptic state. These same progenitors contribute to adult melanophores (black cell) and at least some xanthophores (orange cell). Additionally, some embryonic/EL melanophores persist into the adult stage (brown cell), and EL xanthophores lose their pigment, entering a cryptic phase (light yellow cell), and then reacquire pigment at a late stage of adult pattern development. ZFA:0005929 Lecophores that develops from xanthophores. Xantholeucophores are located on the anal fin. Xantholeucophores contain round organelles carotenoid vesicles containing yellow/orange pigment as well as irregular organelles indistinguishable from pterinosomes, which contain yellow or colorless pteridines. During development white pigmentation surrounds a yellow-orange center, gradually increasing until whole cell appears white. Xantholeucophore express aldehyde oxidase 5 and purine nucleoside phosphorylase 4a. These cells most closely resemble the leucophores of other teleost. ceriv zebrafish_anatomy 2020-11-04T14:18:50Z xanthophore leucophore unknown adult
