查询词典 oogenesis

In ovary, PNA receptors appeared in the oocyte cytoplasm of second phases of oogenesis; the positive granules gradually increased from third to forth phases, and they exhibit a maximum expression before vitellogennic stage in cytoplasm of oocyte; from vitellogennic stage to chorionation stage, the positive granules gradually reduced. Binding sites on follicle cells were changed with their morphological variation in every stage of oogenesis.The staged and specific expression of oncogene c-kit, the tyrosine-kinase receptor, is closely related with gametogenesis.

2在中华蚱蜢卵子发生的早期，PNA受体是由卵母细胞自身合成；在卵黄发生前的准备时期，卵母细胞质中的PNA受体一部分来源于自身合成，另一部分则来源于滤泡细胞，而糖复合物的大量出现可能直接与卵黄发生有关；卵黄发生期PNA受体的减少可能是在卵黄物质形成中部分发生了修饰；卵黄和卵壳的相继形成过程中，阳性反应的出现说明PNA受体参与了卵黄膜及卵壳的形成，而这些受体物质是由滤泡细胞分泌的。
