卵裂

We also confirmed in this paper that it is injected somatic cells but not broken cytoplasm formed multi blastomere through mitosis in the reconstructed embryos.

在本实验中还通过用DNA染料（Hoechst-33342）对核移植体进行染色的方法，对融合后成纤维细胞在核移植体内不同时间的运行及发育模式进行了观察，确认了是成纤维细胞经有丝分裂形成多个卵裂球而不是由于细胞质碎裂形成的两个或多个碎块。

Three types of cells were transferred into perivitelline space under zona pellucida of rabbit oocytes respectively.

用体外培养14代和24代的小鼠胚胎干细胞构建的异种重构卵的卵裂率分别是88.5％和82.1％(P＞0.05)，囊胚发育率分别是16.7％和15.4％(P＞0.05)。

Ovine immatured oocytes, matured oocytes and embryos from 2-cell stage to blastocyst produced in vitro were recovered, and RT-PCR was used to semi-quantify mRNA expression. Proteins of Cx43 and Cx45 were detected by using a combination of immunocytochemistry and Laser Scanning Confocal Microscope.

收集绵羊未成熟和成熟卵母细胞以及体外受精早期胚胎各发育阶段的卵裂球细胞，通过RT-PCR半定量检测Cx43和Cx45基因的mRNA表达量；通过免疫组织化学方法结合激光扫描共聚焦显微镜检测Cx43和Cx45蛋白在绵羊体外受精的早期胚胎发育过程中的表达情况及表达区域。

Meanwhile to explore the influence of psychosocial stress factors on oocyte maturity, the number of retrieved oocytes and merogenesis, the plasma levels of A and NA and the follicular fluid levels of NA, estrogen and androgen were examined in pregnant and non-pregnant women.

并通过对妊娠与未妊娠妇女血浆中A、NA及卵泡液中NA、雌激素、雄激素水平测定，结合获卵数和卵裂数进行相关性研究探讨心理社会因素对卵泡发育成熟的影响。

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。

Embryo cells display a synchron cleavage rhythm during the cleavage stage, there is almost no gene transactivation, which is regulate and operated by the mRNAs and protein of oocyte.

卵裂阶段的胚胎细胞呈现同步化的分裂节律，鲜有基因转录活动，其发育由源自卵母细胞发生期间合成的蛋白质和mRNAs调控。

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。

Owing to placenta and milk transshipping effect, the content of Aroclor 1254 in fetal and infant vivo was very low, so there were not significantly pathological changes in sexual gland, the effect of Aroclor

2首次以排卵数、受精率、受精卵的第一次卵裂率、桑堪胚发育率、囊胚~孵化胚发育率、以及发育延迟胚和退化变性胚的比率，对个体发育的不同时期接触不同剂量 AroClor 1254对小鼠卵子发生、受精和附植前胚胎体内发育毒性进行系统定量。

These zygotes were divided into four groups according to the different zygote pronuclei orientation and the developmental potential.

根据早期卵裂时间及原核构型不同进行筛选而移植的129个体外受精、卵胞浆内单精子注射周期，共1 032个正常受精卵为资料。

Methods and Results Experiment 1: Intracytoplasmic injection of rat sperm heads was performed using 7~10 μm and 2~4 μm diameter pipettes and different injected method respectively.

方法和结果实验1：用直径为7~10μm和2~4μm的注射针以及相应的注射方法进行大鼠ICSI，ICSI后卵母细胞存活率(30.5% vs。 61.3%)和卵裂率(12.5% vs。 51.1%)均差异显著(P.05)；实验2：分别在hCG后14 h、16 h和18 h取卵进行ICSI，三组存活率77.4%、74.1% vs。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
