查询词典 gastrulation

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

The rearrangement of the blastula into a three-dimensional organism with inner middle and outer layers occurs during gastrulation.

在原肠胚形成过程中，囊胚重新排列，形成包括内层，中层，外层的三围组织。

Although overexpression of Hspa5 does not cause detectable defects, its knockdown by injecting Hspa5 morpholino antisense oligonucleotides results in slower epiboly during gastrulation and dorsalized phenotypes at 24 hpf, including smaller and curled tail and absence of caudal ventral fin. When Hspa5 expresison in embryos is knockdown, the expression of the dorsal markers gsc and ntl is enhanced while the expression of ventral markers is reduced.

尽管在胚胎中过量表达Hspa5对胚胎发育没有明显影响，但是利用反义吗啉环寡核苷酸抑制胚胎中Hspa5的表达会导致胚胎外包变得缓慢，24hpf出现尾部变细或卷曲、缺少腹鳍等背部化的表型，同时gsc和ntl等背部标记基因的表达增强，但eve1等腹部标记基因的表达减弱。

GFP expression started during gastrulation in the axial hypoblast layer.

将pShh-EGFP 注射到斑马鱼1-细胞期内的受精卵中，定期在倒置荧光显微镜下观察GFP的表达。

GFP expression started during gastrulation in the axial hypoblast layer. During segmentation, GFP was detected in the notochord but not in the foor plate.

GFP在原肠作用期就开始表达，主要发生在中轴下胚层中；在体节形成期，GFP在脊索细胞中表达，但未发现在神经底板细胞中表达。

We propose that the noncell-autonomous effects of Spemann's organizer on dorsoventral patterning are executed in part by diffusible signals that directly bind to and neutralize ventral BMPs during gastrulation.

我们提出，施佩曼组织器对背腹式的非细胞自发功能，有部分是通过原肠胚形成过程中，直接结合和抵消腹部BMP的扩散性信号所发挥的。

A variation in gastrulation, involving the movement of cells into endodermal and mesodermal positions through the thickened primitive streak, arose in reptiles and can still be seen in bird and mammalian embryos, lending support

密实的原肠胚通过细胞运动进入内胚层和中胚层，爬虫，鸟，哺乳动物的胚胎都如此。因此提出这样的理论，鸟类和哺乳动物是由爬虫进化而来的。

This is a process known as 'gastrulation'.

这一过程称为&原肠胚形成&。

It is required for the formation of the primitive streak during mouse gastrulation.

它在小鼠原肠期的原条形成过程中起重要作用。

Since the altered dorsal-ventral domain was started at early gastrulation and became more obvious at the late gastrulation stage, P5 and P4 both may affect cell fate maintenance through regulating cell migration during gastrulation period.

因为cyp11a1表现下降的鱼卵是在原肠期刚要开始的时候才开始出现不正常腹部组织增大，而且随著时间的增加而更加明显，所以P5和P4可能是藉由影响原肠期的细胞移动进而去影响后来的细胞分化。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
