囊胚的

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。

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。

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。

Objective: We try to elucidate the probable mechanism of midblastula transition in zebrafish through study the cyclin C gene which is expressed maternally and zygotically during zebrafish embryo development.

斑马鱼胚胎发育过程中cyclinC基因母型和合子型表达的初步研究目的：通过研究cyclin C基因在母型和合子型的表达研究，阐释其在中囊胚过渡时期的可能作用。

GFP fluorescence was visible early at the 2-cell stage and then became stronger in the blastocysts of all three species. However, the distribution of the GFP signals was restricted to the cells of inner cell mass and no fluorescence was detectable in trophectoderm cells.

结果显示：牛Oct-4启动子驱动的GFP基因在3个物种的2-细胞胚胎就已经开始表达，在囊胚期表达加强且只特异表达于内细胞团中，而不表达于滋养层。

Although Pygo expressed ubiquitously in the embryo, it expressed at relatively high level in pre-blastoderm embryos which indicated a high degree of maternally provided message, followed by a low level of ubiquitous zygotic expression.

结果表明，虽然pygo普遍表达于整个胚胎中，并且在果蝇胚胎发生全过程都有，但Pygo在前囊胚层(pre-blastoderm)中的表达水平相对较高，这说明胚胎发生过程中来自母方的贡献较高。

Mouse embryonic stem cells are pluripotent cell lines isolated from the inner cell mass of blastulas which can proliferate unlimitedly and have ability of self-renewal.

中国农业科学院，动物遗传育种与繁殖，2009年，博士 \'胚胎干细胞是从囊胚内细胞团分离出来的，具有无限增殖、自我更新的能力。

Methods Mouse endometrial epithelial cells were isolated and cultured,then it was cocultured with mouse embryos fertilized in vitro.

对小鼠子宫内膜上皮细胞进行分离、培养鉴定，然后与体外受精的小鼠胚胎进行共培养，观察共培养对小鼠胚胎卵裂率、孵化率以及囊胚期胚胎总细胞数的影响。

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。

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。
