中胚层细胞的

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。

We hypothesized that Notch signaling might play an important role in specifying endothelial progenitors from the mesoderm, given that this pathway acts as a bipotential cell-fate switch on equipotent progenitor populations in other settings.

由于在其他系统中的研究表明，Notch信号通路在同一潜能的前体细胞走向两种不同命运的过程中发挥着关键的转换作用，我们假定该通路在中胚层特化为内皮前体细胞的过程中也发挥重要功能。

The part of the embryonic mesoderm, consisting of loosely packed, unspecialized cells set in a gelatinous ground substance, from which connective tissue, bone, cartilage, and the circulatory and lymphatic systems develop.

间叶细胞胚胎的中胚层部分，由生长于胶状基质的、结构松散的、无特定功能的细胞组成，这些细胞将会发育成结缔组织、骨、软骨、血液及淋巴系统

间叶细胞胚胎的中胚层部分，由生长于胶状基质的、结构松散的、无特定功能的细胞组成，这些细胞将会发育成结缔组织、骨、软骨、血液及淋巴系统

Generally we think muscular histogenesis has many steps of biology, including foetal mesoderm merotomy; myoblast shapes in arthromera; myoblast can form muscular tissue to move to limbs; the proliferation of sarcoblast can increase cells\'quatity.

一般认为，肌组织发生是一多步骤的生物学过程，包括胚胎中胚层的分节；成肌细胞在体节形成；成肌细胞向四肢迁移形成肌组织；成肌细胞增殖以增加细胞数量。

Possibly RS cells are a kind of mesoblastic precursor cells, possessing better self- renewal and differentiation capacity.

RS 细胞较之mMSC细胞可能是一种更原始的中胚层前体细胞，具有更强的自我更新和分化潜能。

Fibroblast growth factor signaling guides mesodermal cell migration; however, we found some directed dorsal migration in an FGF receptor mutant, which suggests that additional signals are involved.

显微元细胞增长因子信号知道着中胚层的细胞迁移；但是，研究人员发现在突变FGF受体中存在着定向的背离迁移作用，这说明有更多的信号参与到了细胞的运动当中。

Their ability to self-renew and differentiate into tissues of mesodermal origin (osteocytes, adipocytes, chondrocytes) and their lack of expression of haemopoietic molecules are currently the main criteria for isolation.

当前分离的主要标准是根据他们自我更新并向中胚层来源组织（骨细胞，脂肪细胞，软骨细胞）分化的能力以及缺乏造血相关分子表达的特点。

Human basic fibroblast growth factor is a single-chain heparin-binding polypeptide. It is a general regulatory mediator for different cells such as endothelial cells and for other cells of mesodermal and neuroectodermal origin, it stimulates cells proliferation, inducing or delaying differentiation.

人碱性成纤维细胞生长因子是一种单链的具有与肝素结合能力的多肽分子，它能够调节内皮细胞及其它来源于中胚层和神经外胚层等多种细胞的生长、分化、迁移和凋亡，同时是一种重要的血管生成因子，因此具有广泛的临床应用价值。

Flounder FoxD1 mRNA was over expressed in one cell of the two-cell stage zebrafish, MyoD expression in the somites on one side was reduced, but the expression in the adaxial cells was not affected; Myf5 expression in the presomitic mesoderm, adaxial cells and somites on one side was reduced.

在斑马鱼中过量表达FoxD1后，MyoD在一侧体节中的表达受到了严重抑制，而在近轴细胞中的表达未受影响，Myf5在体节前中胚层，近轴细胞，及体节中的表达都受到了抑制。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
