外胚层

Objectives: Being able to simultaneously express all genes of germline, endoderm, mesoderm and ectoderm, bone marrow mesenchymal stem Cells are considered to have the potential to differentiate to other tissues and cell lines.

目的 骨髓间充质干细胞(Mesenchymal Stem Cells，MSCs)能同时表达内胚层、中胚层和外胚层等所有三个胚层的基因，具有向其它细胞和组织多向分化的潜能。

The mean somatotype data of male was 6.4-2.7-3.0, which focused on balanced endomorphy. The mean somatotype data of female was 4.8-2.3-3.0, focused on ectomorphic endomorph.

青岛高校男性大学生平均体型值为6.4-2.7-3.0，属于均衡的内胚层体型；女性平均体型值为4.8-2.3-3.0，属于偏外胚层的内胚层体型。

According to NIH team leader Ronald McKay, that means epiblast cells offer scientists a iew of an ES cell just as it's poised to produce mature cell types, including neurons, muscle and bone.

根据美国国家卫生所的研究小组负责人Ronald McKay的说法：这就意味着外胚层细胞给予科学家一种胚胎干细胞全新的观点，那就是他是一种制造成熟细胞类型，其中包括神经，肌肉和骨的一种平衡。

Scientists at the NIH, Britain's Cambridge and Oxford Uniersities and the Karolinska Institute in Stockholm reported their discoery of so-called "epiblast" stem cells oernight in two papers in the journal Nature.

美国国家卫生所，英国剑桥大学与牛津大学与斯德哥尔摩的Karolinska研究所的科学家把他们称为"外胚层"的干细胞的发现的两篇论文连夜发表在《nature》杂志上。

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。

Here we show reprogramming of advanced epiblast cells from embryonic day 5.5–7.5 mouse embryos with uniform expression of N-cadherin and inactive X chromosome to ES-cell-like cells in response to LIF–STAT3 signalling.

李喜和与剑桥大学合作开展的这项研究，首先是对着床后5.5—7.5天小鼠外胚层细胞诱导培养过程中关于LIF因子作用的重新认识。

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。

The middle embryonic germ layer, lying between the ectoderm and the endoderm, from which connective tissue, muscle, bone, and the urogenital and circulatory systems develop.

中胚层中间胚芽层，位于外胚层和内胚层之间，最终发育成结缔组织、肌肉、骨骼、泌尿系统及循环系统

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。
