太平洋牡蛎卵母细胞发育及卵黄发生的超微结构

Ultrastructural studies on development of oocytes and vitellogenesis of Crassostrea gigas

利用透射电镜观察了太平洋牡蛎（ Ｃｒａｓｓｏｓｔｒｅａ ｇｉｇａｓ） 卵母细胞的发育及卵黄发生。卵母细胞的发育可分为卵黄合成前卵母细胞与卵黄合成期卵母细胞２ 个阶段。卵黄颗粒来源于线粒体、内质网、高尔基体、吞饮小泡等多种细胞器。

The ultrastructure of oocytes and vitellogenesis of Crassostrea gigas were studied with transmission electron microscope. The development of oocyte can be divided into 2 stages,which are previtellogenic oocyte and vitellogenic oocyte. The yolk originated from many organelles, including mitochondria, golgi vescle,rough endoplasmic reticlum, micropinocytic vesicles and so on.
