胚层

Mesenchymal stem cell, originating from mesoblast, resides mainly in post-natal bone marrow as well as human umbilical cord blood, and coexists with hematopoietic stem cell.

间充质干细胞起源于中胚层，主要位于成体骨髓和人胎儿脐血，与造血干细胞共存。

The effects of fenvalerate, phoxim and their mixture at about doses of LD〓 separately on the larva with 4 instars of cotton bollworm in development, spermatogenesis, spermateliosis and male mesoblast gonad were studied with micro-application method.

以毛细管点滴法，分别研究了约LD50剂量的氰戊菊酯、辛硫磷及其混剂对棉铃虫4龄初期幼虫的生长发育、精子发生与形成以及雄性中胚层生殖腺的影响。

It was needed only 20-30 minutes; the active components can be transformed into high concentration active substances, nonstop to the deep skin, the active components infiltrate to Subcutaneous tissue through the channels among Hair follicles, sweat glands and cells, reach the mesoblast .then it open the entrance easily by stimulating the water channels protein on the cell membrane, infiltrate the cell membrane, make the skin cells to absorb nutrients plenary.

需20-30分钟即可将活性成分快速转换成高浓度的活性物质，直达深层皮肤；利用"水电泳"技术，活性成分通过毛囊、汗腺与细胞间通道渗透皮下组织，达到中胚层通过刺激细胞膜上的"水通道蛋白"，轻易打开入口，渗透细胞膜，使皮肤细胞充分吸收营养成分

PartⅠTheoretical Research MSCs is stem cells capable of multi-directional differentiation arising from mesoblast, which principally lies in stroma of connective tissues and organs, especially abundant in marrow, even divorted from fetal umbilic blood, differentiates into osteocytes, chondrocytes, tendon cells, myoctes, nerve cells, adipose cells and hematopoiesis stromal cells and so on.

理论研究间充质干细胞(mesenchymal stem cells，MSCs)是中胚层来源的具有多向分化能力的干细胞，主要存在于全身结缔组织和器官间质中，以骨髓组织中含量最为丰富，胎儿脐血中亦可分离得到。

Many signaling pathways play important roles in the formation of mesoderm and patterning of the neuroectoderm during early development of vertebrate embryos.

在脊椎动物胚胎的早期发育中，多种信号途径对中胚层形成和神经外胚层分化起着重要的调节作用。

Mice without Nodal gene will die due to the lack of mesoderm formation.

Objective:To study the feasibility of sonographic diagnosis and differential diagnosis for uterine sarcoma in mesoderm al tumor of myometrLMm.

目的 ：应用B型超声对较罕见的子宫肌膜中胚层恶性肿瘤进行鉴别诊断。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
