囊胚

The transcripts of XSox1 are detected in the animal pole at cleavage and blastrula stages and mainly in the central nervous system and the developing eye at neurula stages.

原位杂交结果显示，在早期卵裂阶段和囊胚期，Sox1基因主要在动物极表达；从神经板期开始，Sox1基因主要在中枢神经系统和眼原基中表达。

By this time, it has developed into a hollow ball of cells called blastocyst .

到这个时候，它已经发育成一个叫囊胚的中空细胞球了。

There is a good deal of variation in blastocyst size before implantation but it is not known whether this is related to survival rate.

囊胚的大小在定植前有很大的差异，但是目前还不知道这会不会影响到胚胎的存活率。

An embryo that has developed for five to six days is called a blastocyst.

1胚胎已发展为5时55天是所谓的囊胚。

Further more, 22% and 67% of cultured embryos developed to blastocyst stage after 96 hours of culture.

在M16中同时添加2.5mM牛磺酸和100μM EDTA两种成分可使1—细胞胚胎的囊胚发育率达到67％。

Further research is needed to find the more suitable treatment and to improve the rate of blastocyst formation in porcine ICSI.

此外，需进一步研究去找寻适当的处理方式，改善猪ICSI的囊胚发育率。

In addition, the above three media could also support the development of 1 cell embryos to hatching blastocyst stage.

实验2的结果表明，在M16培养液中单独添加2.5mmol/L的牛磺酸也可支持体外培养的昆明小鼠1-细胞胚胎发育到囊胚。

Blastocyst formation is a crucial stage in early embryo development.

囊胚形成是胚胎早期发育过程中一个重要阶段。

The results of experiment shown the hetero-reconstructed embryos could further develop into blastocyst stage in vitro.

实验结果表明，小鼠、兔异种间的核移植重构胚胎可在体外完成到囊胚阶段的早期发育。

Methods The B6D2F1 hybrid mouse oocytes were parthenogenetic activated with strontium chloride(SrCI2) and cytochalasin B. The parthenogenetic blastocysts and morulas were seeded on MEF feeder respectively to examine the primary ICM appearance.and compare the derivation rate.

采用氯化锶联合细胞松弛素B激活B6D2F1杂交小鼠卵母细胞，所获得的囊胚与桑椹胚分别用于孤雌胚胎干细胞的建系，观察两者的建系成功率。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.

这是凯特，那个是爱朗。
