外胚层的

An embryo at the stage following the blastula, consisting of a hollow, two-layered sac of ectoderm and endoderm surrounding an archenteron that communicates with the exterior through the blastopore.

原肠胚一种囊胚之后的胚胎，含有中空、两层的外胚层和内胚层，包围着通过胚孔跟外界交流的原肠

Cumulative data have been documented that mesenchymal stem cells can differentiate into osteoblasts, chondrocytes, adipocytes, tenocytes, myotubes, neural-like cells, hematopoietic-supporting stroma and other non-hematopoietic cells derived from mesoblast or ectoblast.

大量研究表明，体外培养的骨髓间质干细胞在合适的诱导条件下，可分化为成骨细胞、成软骨细胞、脂肪细胞、成肌细胞、成腱细胞和神经元样细胞等多种非造血组织特别是中胚层和神经外胚层来源的组织细胞。

All of the FGFs family are the mitogen,affecting the ectoderm,entoderm and the mesenchymal cells.

全部的FGFs都是广谱的有丝分裂原，作用于外胚层、内胚层和间充质来源的细胞。

One way by which IKK- controls skeletal and craniofacial morphogenesis is by repressing expression of fibroblast growth factor family members, such as FGF8, whose expression is specifically elevated in the limb bud ectoderm of IKK--deficient mice.

IKK控制骨骼和颅面形态发生的一个途径是抑制成纤维细胞生长因子家族成员如FGF8的表达，后者的表达在IKK缺失小鼠肢芽外胚层中特异升高。

Germ potential is established after conception in a totipotent zygote and retained subsequently during development in blastomers of morula , cells form the inner cell mass of blastocyst , epiblast and population of primordial germ cells .

种子潜能的确定是全能的受精卵形成之后，并且随后在桑葚胚，胚泡内层细胞，外胚层和原生殖细胞的发育过程中保留。

In zebrafish, the expression of fez becomes detectable at the anterior edge of the presumptive neuroectoderm by 70% epiboly.

本文用整体原位杂交的方法揭示了在斑马鱼胚胎发育过程中，Fez基因的表达最早出现在原肠期胚胎头部未来的神经外胚层细胞中，此时胚盘仅下包约70％。

Our studies indicate that fez is one of the earliest markers specific for the anterior neuroectoderm and it may play a role in forebrain development by regulating Dlx gene expression.

本文的研究证实Fez基因是最早在胚胎前端神经外胚层中表达的标志性基因之一，并有可能是通过调节Dlx系列基因的表达而在前脑发育过程中起作用。

But on the other hand, they have contacts all know, there is no long teeth really rare (apart from a very small number of so-called "congenital ectodermal dysplasia," outside of the case).

但是反观就们所接触、所认识的所有人，没有长牙的真的很少见(除了非常少数所谓&先天性外胚层发育不良&的病例以外)。

Blastocyst implantation is the progress of the invading and adhesion between trophectoderm and uterine endomembrane, which involved in the remodeling of the tissue of uterine.

胚胎着床是滋养外胚层细胞和子宫内膜细胞相互黏附和侵入的过程，涉及着床点和着床旁组织的重塑。

However, cell counts and inner cell mass to trophectoderm ratios of the embryos exposed to elevated temperature were not different from controls, suggesting that the developmental potential of the embryos which survive to blastocyst stage are not overtly impaired.

然而，处理组牛胚在温度升高过程中，发育到第9天的囊胚数，细胞数及内细胞团与滋养外胚层比率在统计学上与对照组之间没有差异。由此揭示，升高温度对牛囊胚期胚胎的发育没有明显损害。
