title: Induction of xanthophores from non-pigmented dermal cells of xanthic goldfish in vitro.
abstract: To identify precursor cells of xanthophores (xanthoblasts), non-pigmented cells without any phenotypic traits as pigment cells were isolated from the dermal tissue of xanthic goldfish with an adult color pattern and cultured in a medium containing 1 mM db-cAMP or 0.25 U/ml ACTH and 10% carp serum. These non-pigmented cells differentiated into xanthophores which showed a dendritic morphology and contained a large quantity of fluorescent pteridines and numerous vesicular inclusions. Sepiapterin was the major component, and the vesicles contained fuzzy material in addition to small membranous elements. The fluorescent pattern and the morphological characteristics indicated that the differentiated pigment cells were xanthophores of larval type.
