摘要:

黑色素生成相关细胞的研究,对于丰富色素细胞学内容和黑色素沉积量的调控具有重要意义。本试验通过透射电镜,观察泰和乌骨鸡皮肤黑色素生成相关细胞的超微结构。结果表明:在泰和乌骨鸡皮肤胶原纤维束中有较多形态不规则的黑色素细胞。黑色素细胞内有电子密度高,大小不等的圆形黑素体。黑色素细胞的周围胶原纤维束中含有很多形态不规则,明显比黑素体小的黑色素颗粒。此外,紧靠在黑色素细胞外周有多泡脂肪细胞。多泡脂肪细胞内含有多个脂肪囊泡,其内可见有黑色素颗粒分布。研究结果提示,黑色素颗粒对于多泡脂肪细胞内脂肪囊泡的形成可能具有重要作用。

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.
