RT-PCR results indicate the gastrulation and germ lines relating genes expression modes are different.

RT-PCR结果显示，在Wnt3a与Activin A共同作用下，原肠作用基因及三胚层发育相关基因表达的时间有差异。

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。

DATA SYNTHESIS: The mesenchyma stem cells ware a kind of plurpotent stem cell in mesoderm, with powerful multiplication ability and multi-directional differentiation potential.

资料综合：间充质干细胞是属于中胚层的一类多能干细胞，具有强大的增殖能力和多向分化潜能，动物模型试验和临床应用研究也取得了一定的效果。

Compared with other signals, TGFβ/Nodal plays a key role in the induction of mesendoderm.

相比于其他信号通路，Nodal信号通路对于胚胎的中内胚层的诱导起到关键的作用。

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。

The present case report explains echographic features of a Mesoblastic Nephroma diagnosed at the 31 weeks of pregnancy and make a brief discussion.

我们的这个病例就提供了一例在孕31周诊断的中胚层肾瘤的回声特征并做了简单的讨论。

Because of this findings a Congenital Mesoblastic Nephroma s. a Wilms's tumor were proposed as possible diagnosis.

根据这些表现推测可能的诊断为先天性中胚层肾瘤或Wilms'肿瘤。

Because of this findings a Congenital Mesoblastic Nephroma vs. a Wilms's tumor were proposed as possible diagnosis.

根据这些表现推测可能的诊断为先天性中胚层肾瘤或Wilms'肿瘤。

The final diagnosis was Congenital Mesoblastic Nephroma .

最终诊断为先天性中胚层肾瘤。

Bone marrow-derived mesenchymal stem cells are a population of cells capable of replicating as undifferentiated cells and that have the potential to differentiate to lineages of mesoblastic origin. And the characters of BMSCs have suggested the great value of this specific cell population for tissue engineering.

骨髓间充质干细胞具有自我复制、未分化的特点，并可在不同条件下分化为中胚层起源的多种细胞，这些特点决定了其在组织工程中的重要地位。

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。
