卵母细胞

The rates of activation and cleavage depend on the age, origin, and culture conditions of the oocyte.

孤雌激活的效果与激活方法、卵母细胞的卵龄、来源和培养条件等有关。

The polar body extrusion process of induced maturation is similar to naturally fertilized eggs.

在卵母细胞成熟过程中有受精膜举起的现象，说明精子入卵不是受精膜举起的必要条件。

Methods Male infertility couples from October 2006 to July 2008 were chosen and divided into ICSI group and TESA+ICSI group. ICSI group were 584 oligozoospermia cases with alive normal sperm in spermatic fluid. TESA+ICSI group were 54 obstructive azoospermia cases with alive normal sperm in testicle. Two groups were treated with ICSI after wives obtained oocytes by ovarian stimulation.

选择2006年10月～2008年7月因男性不孕症夫妇行ICSI治疗的患者638例分成两组，ICSI组和TESA+ICSI组，ICSI组为自行排精后精液内可以找到正常形态活精子的少精症患者行ICSI治疗584例，TESA+ICSI组为梗阻性无精子症患者经睾丸穿刺找到睾丸内形态正常活精子行ICSI治疗共54例，两组女方均给予超促排卵用药获取卵母细胞。

Objective To investigate CD_(44) and interα-trypsin inhibitor expression in the cumulus-oocyte complex of mice.

目的探讨CD44和间α胰蛋白酶抑制剂在小鼠卵丘-卵母细胞复合体的表达及两者的相关性。

Therefore, the oocytes quality decline induced by ooplasmic defect may be the main reason that cause older female sterility and pregnancy failure.

因此，卵胞质缺陷诱发的卵母细胞质量的下降可能是引起许多老龄妇女不育和怀孕失败的主要原因。

Ooplasmic transfer increases the fertilizability of the aged oocytes and the early embryonic viability, it has led to the birth of health babies, and become a hotspot in the realm of human assisted reproduction biotechnology and animal clone.

卵胞质转移技术能有效改善老龄卵母细胞的受精能力和早期胚胎的发育能力，在人类已有健康后代出生，它已成为人类辅助生殖生物技术和动物克隆研究的新热点。

In this study, the effects of STH and insulin on porcine in vitro oocyte maturation and cleavage after parthenogenetic activation were investigated.

研究了生长激素、胰岛素单独或者联合作用对猪卵母细胞体外成熟及孤雌激活后卵裂的影响。

It is valuable to discover the function of signal molecules with investigations ontheir expression and localisation in oocytes.

研究信号分子在卵母细胞内的表达与定位对于阐明这些分子在卵内的功能具有重要作用。

Indirect immunofluorescence was used to observe the distribution of fibronectin in human oocyte and 2-cell to morulae embryos.

纤维粘连蛋白均匀分布在体外未受精人卵母细胞和受精后人胚胎早期发育的不同阶段的卵裂球表面，各时期的免疫荧光强度未见明显差别。透明带未见纤维粘连蛋白表达。

At final stage, the oocyte contained many globules, then developed to the mature parthenogenetic ovum really and moved to the female's brood pouch.

后期的卵母细胞含较多的卵黄颗粒，最后成为成熟卵子，排入孵育囊内形成夏卵。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
