查询词典 ectoderm

Furthormore, xNorrin can not activate canonical Wnt signaling in the endomesoderm, suggesting additional mechanisms to restrict xNorrin activity in the ectoderm besides of its RNA localization in the animal pole..

进一步的体内实验表明，xNorrin协同xFrizzled4及xLrp5/6只能在外胚层激活经典Wnt信号通路，而在内中胚层中这种活性则很低，提示除了其RNA定位在动物极细胞之外，还存在着另外一种分子机制将xNorrin的活性限制在背部外胚层。

An embryo at the stage following the blastula, consisting of a hollow, two-layered sac of ectoderm and endoderm surrounding an archenteron that communicates with the exterior through the blastopore.

原肠胚一种囊胚之后的胚胎，含有中空、两层的外胚层和内胚层，包围着通过胚孔跟外界交流的原肠

The outer layer of a blastula that gives rise to the ectoderm after gastrulation.

外胚层囊胚的外层，在原肠胚形成之后生后外胚层组织

It is the result of incomplete disjunction of the cutaneous ectoderm from neural ectoderm during the process of neurulation.

这是在神经胚形成期，皮肤外胚层从神经外胚层分离不完全所致。

The dorsal system is necessary for the development of ventral structures including the mesoderm and neurogenic ectoderm.

背部基因中的突变可以阻止腹部结构的出现，并且胚胎的腹部变得背部化。

We found a high level of cellular organization, with mesoderm cell movements correlating with some but not all ectoderm movements.

他们发现了一个高水平的细胞组织，与中胚层细胞运动有关，而不是与所有的外配层运动有关。

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。

From these studies, we propose that local antagonism of Wnt activity within the anterior ectoderm is required to establish the telencephalon.

根据这些研究，我们提出，Wnt在前外胚层活动的局部拮抗对建立前脑胞来说是必要的。

Derived from two embryonic germ layers, the ectoderm and the endoderm.

双胚层的具有两个胚层的。

In mammals, the primitive ectoderm is an epithelium of polarized cells that differentiates into all embryonic tissues.

事实上，我们的生命开始于一个细胞团，但在24小时内，一些细胞死去，而另一些形成一个空心的细胞球，这就是原始外胚层。
