Subsequently , people found that noggin plays an important role in normal development, especially of inducing dorsal development.

此后发现该基因在胚胎发育中有重要神经诱导作用，尤其是诱导外胚层的背侧发育。

Under appropriate conditions embryonic stem cells have been shown to differentiate in vitro to multiple cell types of endoderm, mesoderm and ectoderm.

一旦撤除分化抑制因素，或添加适当的诱导剂，ES细胞可分化为内胚层、中胚层和外胚层的多种类型的特化细胞。

BACKGROUND: The basic fibroblast growth factor has the obvious promotion function of multiplication of the mesoderm and nerve ectoderm cells, and has the indirect ossification to the bone marrow-derived mesenchymal stem cells.

背景：碱性成纤维细胞生长因子对来源于中胚层和神经外胚层的细胞具有明显的促进增殖作用，对骨髓间充质干细胞具有间接的成骨作用。

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 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

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。

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。

CFC syndrome and CS can be distinguished from NS by the presence of ectodermal abnormalities, mental retardation and a lack of familial cases. CFC syndrome can be distinguished from CS by the rare presence of papillomata, fetal pads, acanthosis nigricans, wrinkled palms and soles, and loose skin of the hands and feet.

心脏－脸－皮肤徵候群及科斯特洛徵候群二者均具有外胚层的异常，智障，及缺乏家族案例，这些可以和努男徵候群区别；而心脏－脸－皮肤徵候群患者罕见乳突瘤，胎儿垫，黑棘皮病，手掌脚掌皱纹及手脚疏松的皮肤，这些可以和科斯特洛徵候群区别。

Nodal and Activin, members of TGF-βsuperfamily, are mediated by the TGF-βreceptors ALK4 or ALK7, and they play important roles in mesendoderm induction and anteroposterior patterning of the neuroectoderm.

TGFβ家族的信号转导由TGFβ受体ALK4或ALK7介导，在脊椎动物胚胎的中胚层和内胚层诱导以及神经外胚层的前-后轴线分化中起着重要作用。

Thickened midline plate of neuroectoderm that develops into the neural tube, giving rise to the central nervous system.

神经外胚层的中线板增厚形成神经管，发展成日后的中枢神经系统。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
