外胚层

Furthormore, xNorrin can not activate canonical Wnt signaling in the endomesoderm, suggesting additional mechanisms to restrict xNorrin activity in the ectoderm besides of its RNA localization in the animal pole..

进一步的体内实验表明，xNorrin协同xFrizzled4及xLrp5/6只能在外胚层激活经典Wnt信号通路，而在内中胚层中这种活性则很低，提示除了其RNA定位在动物极细胞之外，还存在着另外一种分子机制将xNorrin的活性限制在背部外胚层。

The outer layer of a blastula that gives rise to the ectoderm after gastrulation.

外胚层囊胚的外层，在原肠胚形成之后生后外胚层组织

The formation of a gastrula from a blastula by invagination.

外胚层囊胚的外层，在原肠胚形成之后生后外胚层组织

It is the result of incomplete disjunction of the cutaneous ectoderm from neural ectoderm during the process of neurulation.

这是在神经胚形成期，皮肤外胚层从神经外胚层分离不完全所致。

Consistent with this, oral teeth are proposed to arise exclusively from ectoderm, contributing to tooth enamel epithelium, and from neural crest derived mesenchyme, contributing to dentin and pulp.

脊椎动物的口腔发育被认为是始于外胚层的内陷，因此牙齿的发育被认为是外胚层和神经嵴来源的间充质。

The results indicate that day 5 p.c.primitive ectoderm cells are able to participate in embryogenesis after be-ing introduced into day 4 p.c.blastocysts and result in the production of adult chimeras.

嵌合体与C_(57)BL/6 J小鼠交配后所得的结果表明，原始外胚层细胞在嵌合体内能形成有功能的配子。上述结果说明，原始外胚层细胞与内细胞团细胞、体外培养的胚胎干细胞一样，具有发育全能性。

The somatotypes developed from Mesomorph-Ectomorphy to Ectomorphic Mesomorphy in male; however, it was from Ectomorphic Mesomorphy, Central, Balanced Ectomorphy, Balanced Endomorphy to Mesomorphic Endomorphy in female. Conclusion: The somatotypes of Tibetan adolescents in Naqu are slim with little fat; musculo-skeletal system is not well developed.

结果：那曲地区藏族青少年男性的体型为中胚层－外胚层型均衡型(2.40-3.52-3.59)，女性为中间型(3.73-3.23-3.21)；男性由中胚层－外胚层均衡型发展为向偏外胚层的中胚层型，女性由偏外胚层的中胚层型经历中间型、均衡的外胚层型、均衡的内胚层型发展为偏中胚层的内胚层型。

Cultured epiblast cells overcome the epigenetic barrier progressively as they proceed with the erasure of key properties of epiblast cells, resulting in DNA demethylation, X reactivation and expression of E-cadherin.

研究结果证明LIF因子对于外胚层细胞的重编程发挥了关键作用，推翻了以前研究人员对外胚层重编程的传统认知。

Hypohidrosis ectodermal dysplasia is a rare congenital disorder that results in abnormalities in the structures of ectodermal origin tissues, such as teeth, eccrine sweat glands, hair and nails.

少汗型外胚层发育不良症是一种罕见的起源于外胚层组织，如牙、汗腺、毛发等发育异常的遗传性疾病。

Paper 2:Mutation analysis of EDA gene in Chinese families with X-linked hypohidrotic ectodermal dysplasiaX-linked hypohidrotic ectodermal dysplasia(XLHED,MIM305100) is a recessive disease characterized by severe hypohidrosis,hypotrichosis and hypodontia.

论文二X连锁无汗/少汗型外胚层发育不良中EDA基因致病突变鉴定X连锁隐性无汗/少汗型外胚层发育不良(X-linked anhidrotic/hypohidroticectodermal dysplasia，XLHED；MIM305100)是无汗/少汗型外胚层发育不良(anhidrotic/hypohidrotic ectodermal dysplasia，EDA)中最常见的一种，约占95%。
