胚胎形成的

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

Embryologic fusion of facial maxillary processes results in formation of paired epithelial strands that traverse the incisive canals caudally and ventrally connecting nasal and oral cavities.

面部上颌突胚胎期融合导致具有上皮组织的鼻腭导管形成，其横行穿过切牙管的后侧及腹侧，联通鼻及口腔。

It is common knowledge that the first cells formed during mammalian ontogenesis have embryological equipotentiality.

在哺乳动物的个体发育期间第一细胞形成有胚胎学等势是平常普通的常识。

The embryonic vessels failed to invade into the labyrinthine layer of placenta, which impaired the embryonic-maternal vascular connection. These defects could not be rescued by wild-type tetraploid blastocysts, excluding the possibility that they were due to the extraembryonic tissues.

组织免疫组化分析结果显示：毛细血管腔异常扩张，排列紊乱，不能形成大血管及细致有序的血管网络；胚外中胚层来源的卵黄囊脏层扁平上皮细胞形态变圆，与内皮细胞连接受损；胚胎血管不能侵入胎盘迷路层，胚体与母体血管连接受损。

These genes play a central role in the developmental processes of the anterior-posterior axis of vertebrates by regulating the fetation,and define body pattern in the vertebrates.

这些基因调节胚胎发育，尤其在脊椎动物前-后轴(antero-posterior axis)的发育过程中起着重要作用，并指导脊椎动物的体型形成。

I. Objective and purpose Glycoproteins and glycolipids on cell surface contain fucose in the glycolinkage, which are associated with embryonic development, organ formation, tumor development and tumor infiltration, such as Lewis blood-type antigens-LeY, LeX, sLeX.

一。目的和意义许多细胞表面糖蛋白或糖脂是含有岩藻糖(Fucose， Fuc)化的糖链，参与胚胎发育、组织器官形成，并且与肿瘤的生长、浸润有关，如LeY、LeX、sLeX等Lewis系血型抗原分子。

Gametogenesis, embryonic development, organism evolution.

配子及胚胎的形成与发育、生物进化的初步知识。

Many signaling pathways play important roles in the formation of mesoderm and patterning of the neuroectoderm during early development of vertebrate embryos.

在脊椎动物胚胎的早期发育中，多种信号途径对中胚层形成和神经外胚层分化起着重要的调节作用。

These results indicated that CB is necessary for synchronization in spindle formation in both oocyte and primary spermatocyte, and that synchronization may be required for subsequent embryo development.

这一结果表明CB的处理可以使精母细胞与卵母细胞同步形成MI纺锤体，使其发育同步，这可能对以后胚胎的发育具有重要作用。

And with enough replications, some of these fused cells went on to form what seemed to be a very human embryo.

在复制到足够程度时，其中一些融合细胞就开始形成很像是人类胚胎的东西。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
