中胚层

It is concluded that the initial ancotomic site of blood island genesis may be is mesoblast of extraembryonic blastoderm rather than the yolk sac; the blood vessel endothelium cells and the blood cells are generated parallel; the PGCs are the common ancestry of angioblast and HSC.

血岛最早发生的解剖位置可能不是卵黄囊而是胚外胚盘中胚层，血管内皮细胞与血细胞平行发生，PGC是成血管－造血干细胞的共同祖先。

The middle zone of the mesoderm of a chordate vertebrate embryo, from which excretory tissue develops.

中胚叶节脊索类脊椎动物胚胎的中胚层的中间部分，最终会发育成排泄组织

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。

Between the ectoderm and endoderm is mesoderm, which forms the muscles, reproductive organs, blood vessels and excretory organs.

在外胚层和内胚层之间是中胚层，它形成肌肉、生殖腺、血管和排泄器官。

Identification of differently expressed genes between normal liver tissue and liver cancer,can provide valuable candidate genes for prevention,diagnosis and therapy of liver cancerBased on phenotype analysis after gene knockout,endoblast transcription factor HNF6 may regulate mesoblast transcription factor Foxfl.

基于基因敲除后的表型分析及其研究，发现内胚层转录因子HNF6调控中胚层转录因子Foxfl的表达，进而通过调控Foxfl的下游基因Notch2的表达而调控胆管的发育和生长。

The sad between male and female was 2.73, the somatotype have obviously sex difference (p＜0.001). conclusion the somatotype of the male youth is mesomorphy, while the sebum cutaneum of female is prone to endomorphy.

粤西大学生体围与皮脂发育特点：男性骨骼肌比较发达，身体比较结实，体型类型高度集中于中胚层体型；女性皮脂发育比较丰满，肌肉相对少，体型偏于内胚层体型。

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。

Vascular development begins when mesodermal cells differentiate into endothelial cells, which then form primitive vessels.

在中胚层细胞分化成内胚层细胞时，血管开始发育，并随后形成最初的血管。

The layer of flat cells of mesodermal origin that lines the embryonic body cavity and gives rise to the squamous cells of the peritoneum, pericardium, and pleura .

间皮起源于中胚层的扁平细胞层，衬于胚胎的原始体腔中，最终发育成腹膜、心包及胸膜的上皮细胞

With the development of embryo, Myf5 expression decreased gradually in somites in the anterior region, but remained strong in the newly formed somites; After 30 somites formed, MyoD expression decreased in the somites except the caudal somites. At the hatching stage, MyoD and Myf5 were expressed in head muscle cells and fin muscle cells. In the growing fish, Myf5 was expressed in the skeletal muscle and intestine, and in adult flounder, Myf5 was only expressed in muscle. In the growing fish and adult fish, MyoD was only expressed in muscle.

在胚胎发育早期，Myf5在近轴中胚层中表达，体节发生过程中，Myf5在体节中表达，MyoD基因最早在分节板的体节前细胞中表达，随后在近轴细胞、体节中表达；随着胚胎的发育，Myf5在成熟体节中表达量降低，在新生体节中表达较强；MyoD自30个体节时期后只在新生的尾部体节中表达，在成熟的体节中表达量降低；在孵化期，MyoD和Myf5在头部及鳍的肌肉、尾部的体节中表达；生长期的牙鲆中，Myf5在骨骼肌和肠中表达，成体牙鲆中，Myf5只在肌肉中表达；生长期的牙鲆及成体牙鲆中，MyoD只在肌肉组织中表达。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
