外胚层

Mouth ectoderm caught into the Hau Road.

口部外胚层陷入成口道。

Unexpectly, overexpression of xNorrin can induce neural formation in the ectoderm cells independent of canonical Wnt signaling pathway.

此外，在外胚层中过量表达xNorrin可以激活神经标记基因的表达，更为重要的是这种激活并不依赖于经典Wnt信号通路，提示xNorrin还可能通过其它机制起作用。

Epidermal stem cells isolate from embryonic ectoderm, mostly locate on the eminentia of upper hair follicle and stratum of hair-lack regions such as palm.

表皮干细胞来源于胚胎的外胚层，毛囊上半部的隆起处数量众多，在缺乏毛发的手掌等处位于表皮的基地层。

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。

The part of the ectoderm in a vertebrate embryo that lies on either side of the neural tube and develops into the cranial, spinal, and autonomic ganglia.

神经脊，脊椎动物胚胎外胚层的一部分。位于神经管的两侧，并逐步发展成头颅神经元、脊髓神经元、自主神经系统神经元

Ectomorph - The Skinny Geek; no matter how much he eats and eats he never seems to gain any weight.

外胚层体型者-瘦长而肌肉不发达者；不管他吃多少却永远不会增加体重。

An ectomorph is generally skinny.

医学上称为"外胚层体型者"或是"瘦型体质者"，他们通常都比较瘦。

In vitro, ES cells can spontaneously differentiate into embryoid bodies containing derivatives of three germ layers.

在体外，ES细胞可自发分化为含有内胚层、中胚层、外胚层来源的多种组织和细胞的拟胚体。

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。

The scientists noted that specialized cells generated from the AFS cells included all three classes of cells found in the deeloping embryo - termed ectoderm, mesoderm, and endoderm.

科学家还发现从羊水衍生的干细胞中生长出来的特定的细胞包含了发育的胚胎的三种细胞类型——外胚层、中胚层和内胚层。
