囊

Cleavage produces a blastula a sheet of cells rounded into a sphere that in most species surrounds a cavity.

卵裂产生一个囊胚，形成的细胞壁球形排列形成一个空腔。

The formation of a gastrula from a blastula by invagination.

外胚层囊胚的外层，在原肠胚形成之后生后外胚层组织

Short time delay dont result in preimplantation embryos death, but impacted blastula rate of pronucleus embryos.

短时间滞留不会引起着床前胚胎死亡，但却使原核胚发育到囊胚能力显著下降。3。

Based on Experiment two, froze-thaw embryos were cultured to the stage of blastula and thentransferred to uterus in experiment three.

试验三：以试验二为基础，将各组冷冻解冻胚胎培养发育至囊胚期进行子宫移植。

The expression of MMPs in eutopic endometrium is different in menstrual cycle, and different kinds of MMPs could be found in endometrium stroma, which may play a role in endometrium remolding, blastula implantation and trophoblast invasion.

在人的正常子宫内膜组织中，不同的MMPs在月经周期中的表达不同，子宫内膜间质可表达数种MMPs，这些酶可能参与子宫内膜重建、囊胚种植及滋养层浸润。

The spherical embryonic mass of blastomeres formed before the blastula and resulting from cleavage of the fertilized ovum.

桑椹胚形成于囊胚之前且处于胚胎期内的球形裂球群，由受精卵细胞的分裂而成

The colony of embryonic stem cell separated from blastula could gain five strains of embryonic stem cell and go down to posterity F7 in vitro.

从培养的囊胚中分离获得的类胚胎干细胞集落，经传代培养获得了5株胚胎干细胞株，在体外可传代培养到7代，冷冻保存复苏后，干细胞仍能存活、增殖。

AIM:Studies on totipotential stem cells using primordial germ cells have the same application prospect as embryonic stem cells, especially for the animals difficult to isolate embryonic stem cells from blastula.

目的：应用原始生殖细胞进行全能干细胞的研究具有与胚胎干细胞同样广阔的前景，尤其适合于难以从囊胚内细胞团中分离培养胚胎干细胞的动物。

GV oocytes with normal shape were not obtained in the group which was stored at 20℃ for 24 h and at 25℃ for 14 h; A blastula rates (64%) of all groups in average was gotten in culturing 2-cell in vitro, and there is no significant difference in temperature and time of storage. After transplantating some of the 2-cell embryos which were obtained from GV oocytes stored at 15'C for 8 h, normal infant mice could be obtained.

在20℃下保存24h和25℃下保存14h时，难以获得形态正常的GV期卵；体外受精获得的2细胞期胚经体外培养，总体上有64%的胚胎发育至扩张囊胚，未见有保存温度和保存时间的显著影响，且利用在15℃保存8h后的GV卵获得2细胞期胚的移植获得正常新生小鼠。

Methods 140 patients whose progesterone below 63.6 nmol/L, no heart tube impulse within 8 weeks or pregnancy test of urine is positive but the blastula were not detected by B ultrasound were divided into two groups, respectively 70 cases.

将在我院就诊的孕早期患者中血孕酮水平低于63.6nmoFL、孕8周仍无原始心管搏动、或者尿妊娠试验阳性而B超未发现子宫腔内有妊娠囊的140例患者，随机分为两组（各70例）。

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。
