内胚层

An embryo at the stage following the blastula, consisting of a hollow, two-layered sac of ectoderm and endoderm surrounding an archenteron that communicates with the exterior through the blastopore.

原肠胚一种囊胚之后的胚胎，含有中空、两层的外胚层和内胚层，包围着通过胚孔跟外界交流的原肠

During this stage, the cells group into three layers, the first is the 'ectoderm' which then in turn generates the 'mesoderm' and 'endoderm' layers.

在这一阶段，细胞分化为3层，第一层是"外胚层"，它最终会形成中胚层和内胚层。

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。

In addition, certain endoderm marker genes expressed in the early stage during in vitro pancreatic differentiation means that these cells are endoderm-like cells.

此外，有内胚层的标的基因表现在体外胰脏诱导分化过程的早期阶段，显示这些细胞为与内胚层相似的细胞。

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 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

The results were:1The mean somatotypes in male 2.2\_4.5\_2.4 and female 4.3\_4.2\_1.5 are balanced mesomorph and endomorph-mesomorph,respectively.2Very significant sexual difference is found in adult's of Dong nationality(P.001) while SAD and T are 2.33 and 11.9 respectively.3Compared with the data home and abroad,the somat...

结果表明：1 侗族成人男女的平均体型值分别为 2 2— 4 5— 2 4和 4 3— 4 2— 1 5 ，侗族成人男女分别属均衡的中胚层体型和内胚层—中胚层均衡体型；2 侗族成人男女间SAD值为 2 33，T为 1 1 9，男女间的体型有非常显著性差异(P 0 0 1 )；3与国内、外资料相比，侗族男女的内、中因子值和男性外因子值居中，女性外因子值最低

Results the male value of somatotype was (2.9-3.9-3.5) and female was (4.9-1.4-3.2), they were balanced mesomorphy and endomorphy-mesomorphy respectively.

结果 男女青年平均体型值分别为（2.9-3.9-3.5）和（4.9-1.4-3.2），男女青年分别属均衡的中胚层体型和内胚层-中胚层均衡体型；男女青年间sad值为2.73，体型有非常显著的性别差异(p＜0.001)。

Results: Findings indicated that the mean somatotype of male was 3.6-4.8-2.1, being in the endo-mesomorphy category, and that of female was 5.6-4.3-1.6, being in the meso-endomorphy category.

结果：男性平均体型值为3 。6 4.8 2 。1 ，属偏内胚层的中胚层体型；女性平均体型值为5 。6 4.3 1 。6，属偏中胚层的内胚层体型。3 0岁以前男性体型以均衡的中胚层体型为主，3 0岁以后转变为偏内胚层的中胚层体型，且随年龄增长变化不大。

In the normal uterus, Cytokeratins immunolabelling were detected in glandular cell, luminal epithelial cell, Vimentin immunolabelling were detected in stromal cell and endoblastic cell; CK7 immunolabelling were not detected in any tissue of the yak utenus.

研究结果显示：未妊娠时，泛角蛋白在子宫内膜腺上皮细胞、腔上皮细胞内表达，波形蛋白在子宫内膜基质细胞内表达，平滑肌肌动蛋白在子宫平滑肌和血管平滑肌内表达，牦牛子宫任何部位均不表达角蛋白7；妊娠30天左右时，泛角蛋白在子宫内膜腺上皮细胞、子宫内膜腔上皮细胞、滋养层细胞、内胚层细胞和尿囊细胞内表达，波形蛋白在子宫内膜基质细胞和内胚层细胞内表达，平滑肌肌动蛋白在子宫平滑肌和血管平滑肌内表达，角蛋白7在尿囊细胞内表达，偶尔在腔上皮细胞的细胞核边缘表达；消化法进行原代培养时，组织经胶原酶消化并通过100目和400目筛网组合可以有效地分离原代子宫内膜基质细胞和子宫内膜腺上皮细胞；分离得到的子宫内膜基质细胞活率达90%以上，并可在体外传代7次以上；分离得到的子宫内膜腺上皮细胞活率可达85%以上，并可在体外传代5次以上；RPMI1640培养基最适合子宫内膜基质细胞和子宫内膜腺上皮细胞的生长，维持子宫内膜基质细胞正常生长的FBS添加量为20%，维持子宫内膜腺上皮细胞正常生长的胎牛血清添加量为30%。

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。
