胚胎

Results Primary RPCs extracted from the neural retina demonstrate certain biological characteristics: the cell population could form neurospheres and younger adherent cells expanded in clusters.

结果 从兔胚胎视网膜神经部分离出的原代视网膜前体细胞具有明显的生物学特性：所培养细胞可形成悬浮生长的细胞团，刚贴壁的细胞成簇状生长，这些细胞用免疫细胞化学染色神经上皮干细胞蛋白表达呈阳性。

Objective To explore the effects of polychlorinated biphenyl congener 153(PCB 153 ) during pregnancy on embryonic development and its mechanism.

目的 探讨多氯联苯同系物PCB1 53 对胚胎生长发育的影响及其作用机制。

There are two methods of collecting cow embryos-- directly through the birth canal, or surgically

收集母牛胚胎的方法有两种，一种是直接通过产道，另一种是施用外科手术。

The gene targeted mice are commonly produced by breeding the heterozygous targeted mice following microinjecting the homologous recombinant ES cells into the blastocoele cavity of 3.5dpc embryos at the blastocyst stage to give birth to chimeric mice.

传统基因敲除获得某一突变基因的纯合体动物首先要利用打靶胚胎干细胞获得嵌合体动物；随后用嵌合体动物与野生型个体交配得到突变基因的杂合体动物；最后才能通过杂合体动物之间的交配来生产纯合体动物。

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。

These data suggest that an active blastocyst is required for STAT3 activation which may be important for embryo implantation.

这些结果表明STAT3的激活需要活性胚泡的存在，可能在胚胎着床过程中起重要作用。

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％。

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 objective is to subjugate and discourage the people, because that allows the elite to continue to rule unopposed.

其目的是压制和打击人民的积极性，因为这可以让实权派继续统治不会沦为反对派。

GOD,this is the second time you vanquished me!

天啊，这是第二次你打败了我！
