查询词典 blastocyst

"In mammals, the fertilized egg or zygote undergo es cleavage (cell division without cell growth) to form a hollow ball or blastocyst."

在哺乳动物中，卵与精子结合而成受精卵，受精卵发生数次细胞分裂后，形成一个中空球形的囊胚。

The proportion of embryos developing to the blastocyst stage was not significantly different between two systems, however the static microdevice environments produced significantly more morulas than did control groups.

胚胎发育成囊胚阶段在两个系统之比率并无明显差异，然而在静态微装置环境比对照组产生明显较多桑葚体。

Here we show that transfer of pronuclei between abnormally fertilized human zygotes results in minimal carry-over of donor zygote mtDNA and is compatible with onward development to the blastocyst stage in vitro.

供体合子mtDNA的转移是很少的，所以该方法有可能防止mtDNA疾病在人类中的传播。

But the latter resulted in significantly more zygotes extruded PBl and developed to blastocyst stage after parthenogenetic activation.

结果发现，成熟液中添加促卵泡素组的卵裂率(74.3％)低于人绝经促性腺激素组(78.6％，P＜0.05)，但是第一极体排出率和孤雌激活后的囊胚率都显著高于hMG组(P＜0.05)。

Early cleavage rate,embryo quality,the rate of blastocyst,implantation and pregnant rates from these zygotes were observed,and the transferred embryos were selected according to the pronuclei orientation and early cleavage time.

根据受精卵原核构型的不同分为四组，结合构型类型及早期卵裂与否进行选择性移植，通过观察优质胚胎率、囊胚形成率、种植率和怀孕率，来评估合子原核构型和早期卵裂与胚胎发育潜力的关系。

In the present study, we collected cumulus cells oocyte complex from ovaries of two different strain mice. The cumulusenclosed oocytes were cultured for 6 h in MEM supplemented with growth factor and FSH. The meiotic maturation of these oocytes has progressed to pro-metaphse Ⅰ stage and the condensed chromosomes are visible under DIC microscope, metaphase Ⅰ spindle even can be detected under Polscope. The metaphase Ⅰ spindles of oocytes were exchanged under such microscopes. After electric stimuli, 91. 6% and 91. 6% karyoplasts-cytoplasm pairs were fused respectively. The resulting oocytes were cultured further in MEM and over 80% of oocytes released the first polar body. 79% and 77% of oocytes formed two pronuclei after in vitro fertilization and the embryos were cultured in KSOM supplemented with amino acids. Over 60% of embryos developed to blastocyst stage.

在本研究中我们在取得两种不同品系小鼠的卵丘卵母细胞复合体后，先将卵丘卵母细胞复合体置于含有多种生长因子和激素的MEM培养液中培养6小时，此时卵母细胞已进入第一次减数分裂的前中期，并且在DIC倒置显微镜下可以看到浓缩的染色体，用Polscope可以发现明显的纺锤体，借助这种显微镜通过显微操作将两种不同品系小鼠来源的卵母细胞的MI纺锤体进行互换，经过三次直流电脉冲作用后，分别有91.6％的胞质—MI核质体对融合，经过进一步的培养后，超过80％的重组卵母细胞排出第一极体，体外受精后分别有79％和77％的重组卵形成双原核，受精后的胚胎在KSOM胚胎培养液中体外培养4天后，超过60％的胚胎发育至囊胚。

Lugalbanda was a god and shepherd king of Uruk where he was worshipped for over a thousand years.

Lugalbanda 是神和被崇拜了一千年多 Uruk古埃及喜克索王朝国王。

I am coming just now,' and went on perfuming himself with Hunut, then he came and sat.

我来只是现在，'歼灭战perfuming自己与胡努特，那麼，他来到和SAT 。
