|
The cutaneous xanthophore differentiation from larvae to adult in Bombina orientalis-the Korean fire bellied toad-is studied with light and electron microscopes. General structure of adult xanthophore which is composed of many pterinosomes and a small quantity of carotenoid vesicles is forming chromatophore complex with other dermal pigment cells. And the cytoplasmic process of xanthophore is distributed just beneath the basement membrane. The first differentiated xanthophore is originated from both rER rich cells and Golgi complex rich cells before and after the feeding larval stage. Formation of the pigment granule is proceeded gradually along the sequental metamorphic stages. After the metamorphosis, rapid multiplication of pterinosome is observed and enlargement of carotenoid vesicle is appeared after hybernation. These pigment granules are seen several structures by the differentiated level.
