Conclusion The electrofusion efficiency may he improved by inserting more somatic cells into PVS when the somatic cells have a low electrofusion efficiency with oocytes.
结论低融合效率的体与卵母电融合时可通过增加PVS中体的数目来提高融合效率。
Then their synthese speed slows down.But the synthese of RNA and DNA inthe follicular cell is continuous during vitellogenesis, which may relate toformation of livetin.
而滤泡上
在卵母卵黄形成期，它的RNA和DNA的合成均较快，因此认为滤泡上合成分泌了一些物质参与卵黄蛋白的形成。
The secondary oocyte now divides again into two new cells of unequal size: a relatively large ootid (mature egg cell) and a minute second polar body.
此时，次级卵母又分裂成两个大小不对等的新：一个相对很大的卵（成熟卵）和一个微小的次级极体。
