卵发生的

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。

Because the signaling molecules RAS and ERK1/2 (extracellular signal–regulated kinases 1 and 2) are activated by an LH surge in granulosa cells of preovulatory follicles, we disrupted Erk1/2 in mouse granulosa cells and provide in vivo evidence that these kinases are necessary for LH-induced oocyte resumption of meiosis, ovulation, and luteinization.

研究人员仍然在试图解析接着发生的那些导致排卵（或在某些情况下没有排卵）的分子信号级联反应。研究人员现在证明，激酶ERK1和ERK2是该激素信号的至关重要的下游标靶。在那些颗粒细胞中缺乏这些酶的雌性小鼠中，其卵母细胞不会成熟，因而不会从它们的滤泡中释放出来。

The adjustment mechanism of the follicular development is very complex. The influence of ovarian local factors and the influence from follicle itself were mainly discussed. During the oogenesis, many ultra microstructure changed.

卵泡发生的调节机制非常复杂，在此重点研究卵巢局部因子对卵母细胞发育的影响以及卵泡各结构间的相互影响，卵母细胞发育的过程中也出现了超微结构的改变。

The porine is the polyembryony animal, many obtains the ovocyte from the porine ovary although but the maturity quite to be low; Because the ROSI technology is does not have to grow the mature sole round sperm cell to pour into directly completely in the ovicell nature, jumped over the spermatozoon in to pass through the physiology and the biochemistry, if the ovicell nature mature or the activation degree were insufficient, added the round immature sperm cell maturity quite inferior reason, very possibly Causes the ROSI micro fertilization defeat.

猪是多胎动物，从猪卵巢上获得的卵母细胞数量虽然较多，但成熟度比较低；由于ROSI技术是将没有完全发育成熟的单一圆形精细胞直接注入卵胞质内，跳越了精子在穿过透明带和卵质膜等过程中所发生的生理和生化反应；如果卵胞质成熟或活化程度不够，加之圆形未成熟精细胞成熟度比较差等原因，很可能造成ROSI受精的卵母细胞内部激活因子蓄积减少和生成不足，引起精核解聚困难、精圆核不能形成、第二极体不能排出、卵母细胞孤雌发育率增加等，使ROSI显微受精失败。

In the female, ER was distributed in the nucleus of oogonia cytoplasm and membrane of early primary oocytes.

因此，可以认为雌性激素ER结合唤醒了&休眠&的卵原细胞和精原细胞，细胞核发生一系列成熟分裂期的变化，从而启动了卵子和精子发生的开始。

The results showed that Golgi complex was an organelle that experienced a series of changes during four stages of the oogenesis of Bullacta exarata , which were oogonia, early vitellogenic oocyte, mid-vitellogenic oocyte and end vitellogenic oocyte.

结果表明，在泥螺卵子发生的四个时期即卵原细胞期、卵黄发生早期、卵黄发生中期和卵黄发生后期，卵母细胞内高尔基复合体经历了一系列的变化。

Those results implied that the field investigation should be started from bund toward middle of field for snail population and weed plants for eggs, and the population of golden apple snail could be managed effectively by adjusting the level of irrigation water.

从埂边向稻田中部调查螺量或从田埂杂草向稻田中部稻株调查卵量，更能代表水稻田福寿螺螺卵量的实际情况；通过调节稻田水位可以控制福寿螺的发生和危害。

Among these factors the effects of the Atlantic subtropical high on locusts occurrence are mainly caused by ground surface temperature that is affected by the Atlantic subtropical high in autumn and winter when the locusts live through and incubate; Therefore the occurrence, the development and the harmfulness of the locust as well as its amount of eggs and imagos are impacted.

其中大西洋副热带高压对我国东亚飞蝗发生的影响主要是由于影响了秋冬季节蝗卵孵化和越冬期间的地面温度，从而影响了蝗卵基数和蝗卵孵化为成虫的数量，进而影响着我国东亚飞蝗发生、发展、危害情况的变化。

Inthe whole process, the oocytes, nurse cell and follicle cell morphology change. Inoocyte yolk formation and growth, the number of its nuclear trophoblast cell nucleoli,lamphrush chromosome with a strong synthetic material; oocytes also some syntheticmaterial; follicle cells in the yolk protein synthesis, provide access to exogenous yolkprotein.

在卵子发生的整个过程中，卵母细胞、滋养细胞及滤泡细胞形态均有明显变化；在卵母细胞生长及卵黄形成期，滋养细胞核内的多核仁现象、灯刷染色体与旺盛的物质合成有关；卵母细胞本身也合成一些物质；滤泡细胞参与卵黄蛋白的合成，并为外源性卵黄蛋白提供通道。
