内胚层的

All of the FGFs family are the mitogen,affecting the ectoderm,entoderm and the mesenchymal cells.

全部的FGFs都是广谱的有丝分裂原，作用于外胚层、内胚层和间充质来源的细胞。

They also indicate that the in itro system using mouse ES cells mimics in io deelopment and should proe useful in the study of molecular mechanisms for endoderm and gut deelopment.

这些结果也显示了利用小鼠胚胎干细胞的体外系统模拟了体内的发育过程，而且对研究内胚层和肠道发育的分子机制是很有用的。

To determine whether the same molecular mechanisms are inoled in the formation process, the expression pattern of transcription factors regulating endoderm and gut deelopment in the mouse embryo was examined by in situ hybridization and compared with in io expression.

为了证明在成形过程中是否也具有相似的分子机制，我们通过原位杂交同体内表达比对的方法来检查小鼠胚胎中调节内胚层和肠道发育的转录因子的表达模式。

Yet in many vertebrate groups, teeth are not restricted only to the oral cavity, but extend posteriorly as pharyngeal teeth that could be derived either directly from the endodermal epithelium, or from the ectodermal epithelium that reached this location through the mouth or through the pharyngeal slits.

但在很多脊椎动物里牙齿的发育不仅只有上述来源，还有向后延伸形成的咽部牙齿，可能由内胚层上皮或经由口腔或口咽裂至此部位的外胚层上皮形成。

Altogether, this study provides an induction protocol to obtain endodermal insulin-producing cell clusters and hepatocyte-like cells from mES cells.

综合以上所有结果，本实验提供了一个可从小鼠胚胎干细胞获得源自内胚层来的产生胰岛素的细胞和像肝细胞的细胞之诱导分化方法。

However, when the oropharyngeal membrane, which forms a sharp ecto/endodermal border, is broken, the fate of these cells is poorly known.

但当作为外胚层和内胚层界限的口咽膜破裂后这些牙齿形成细胞的发育知之甚少。

We conclude that UCMSCs, with a newly demonstrated endodermic differentiation potential, might be an alternative source for liver-directed cell therapies.

UCMSCs新近被证实具有内胚层分化的潜能，可作为肝细胞基因治疗的一个可供选择的来源。

Its absence perturbs the balance between actiation of the JAK–STAT and SHP-2–ERK-1/2–MAPK pathways, resulting in less self-renewal and a greater potential for differentiation into the primitie endoderm lineage.

SOCS-3的缺乏破坏了激活JAK–STAT和SHP-2–ERK-1/2–MAPK信号转导通路之间的平衡，这就导致了较少的自我更新，而是较强的分化成原始内胚层谱系的潜能。

Its absence perturbs the balance between actiation of the JAK-STAT and SHP-2-ERK-1/2-MAPK pathways, resulting in less self-renewal and a greater potential for differentiation into the primitie endoderm lineage.

它的缺乏干扰了JAK-STAT和SHP-2-ERK-1/2-MAPK 通路之间的平衡，最终导致自我更新能力减弱和更易于向原始内胚层分化。

As well as enhancing the specification of distal lung epithelium, this protocol was found to yield cells with a phenotype most closely resembling that of lung-committed progenitor cells present in the foregut endoderm and the early lung buds during embryonic deelopment.

除了提高末梢肺上皮的数量，这一个方法被发现产生了在胚胎发育期间最接近表达在前肠内胚层和早期肺芽表型的细胞。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。

The factory affiliated to the Group primarily manufactures multiple-purpose pincers, baking kits, knives, scissors, kitchenware, gardening tools and beauty care kits as well as other hardware tools, the annual production value of which reaches US$ 30 million dollars.

集团所属工厂主要生产多用钳、烤具、刀具、剪刀、厨具、花园工具、美容套等五金产品，年生产总值3000万美元，产品价廉物美、选料上乘、质量保证，深受国内外客户的青睐
