Abstract:

The investigation on ultrastructure of these cells is necessary to improve pigment cytology and regulate melanogenesis.In the current study,we confirmed the ultrastructure of the Taihe black-bone silky fowl (BSF) skin by the transmission electron microscope.The results showed that many irregular melanocytes were observed between in bundles of collagen fiber.Numerous electron-dense round melanosomes with various sizes were present in melanocytes.Some melanin granules located in collagen fiber were small and irregular contrasted with melanosomes.In addition,some multilocular adipocytes were found and closed the melanocytes.A multilocular adipocyte contained generally considerable electron-lucent round fat uesicaes.The melanin granules were observed in some of fat uesicae.These results suggest that melanin granules may be important to formation of fat uesicae in multilocular adipocyte.
