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 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。

Type A band was detected in nearly all the organs and tissues,when coat color chimerism was over 85%, indicated the ES cellhas a fairly high potential to differentiate into cells of endoderm, mesoderm and ectoderm,In addition, only type A band was observed in the muscles of 6 mice which coat color chimerism is over 85%,the results indicated that these muscles were differentiated only from ES cells.

当毛色嵌合率大于85%时，几乎所有的器官组织都检测到A型条带，显示了ES细胞在发育形成内、中、外胚层的细胞方面具有很高的分化潜能。另外，在毛色嵌合率大于85%的其中的6只嵌合鼠的肌肉中，只观察到A型的条带，表明这些肌肉只单独来源于ES细胞。

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。

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%。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
