查询词典 blastoderm

It underlies the blastodisc early in development and becomes enveloped by the blastoderm during epiboly .

发育早期它在胚盘之下，外包时期变成藉由囊胚包裹。

Planaria is the most simple in three blastoderm animal, its nerve system is ladder-like.This is the bio- evolution of the nerve system.

三胚层动物扁形动物涡虫的神经元连接成梯形神经系，有原始的脑和两条神经索，反映了原始生命反射功能的进化和演变。

Hydra is two blastoderm animal, its nerve system is network-like.

两胚层腔肠动物水螅的神经元连接成网状神经系。

The number of nuclei in synchronous blastoderm is much fewer than that in wild type group, and the distribution of nuclei was uneven, which indicates that the nuclear division in mutated early embryos was asynchronous and maybe some nuclei undergoes degeneration.

推测HIRA可能影响了染色体的结构和组装，从而影响了细胞周期的进程，导致果蝇早期胚胎细胞核分裂异不正常。

Using immuno histochemical analysis was seen a positive staining in the basal cytoplasm of blastoderm embryos at 4 hours. This result confirms that the DLMO is a cytoplasmprotein, not like human LMO protein.

免疫组织化学的分析在0～4小时胚盘外周胞浆中有Dlmo基因的阳性染色信号，结果证实，Dlmo与人类LMO不同，其表达产物是一个胞浆蛋白。

Ontogenesis begins from the fertilized embryo. After the cells proliferation during the embryo cleavage, it enters the stage of blastoderm differentiation、 tissue and organ formation.

个体发育从受精卵开始，经过卵裂阶段的细胞增殖后，进入到胚层分化、组织和器官形成阶段。

The results showed:(1) the cellule morphous and the disposition in chick embryo of PGCs were coincident no matter stained by PAS or HE staining, and HE staining could disclose the morphologic characteristics more clearly, exactly and completely;(2) genesis of blood island could be observed at the boundary of light and dark region of the extraembryonic blastoderm at about 26 hours;(3) both the blood vessel endothelium cells and free cells of the blood island were differentiated from PGCs. The generating of genuine yolk sac was at about 44-48 hours.

结果表明：①用经典的识别原生殖细胞的PAS染色方法与HE染色所观察到的PGC在鸡胚的分布及细胞形态基本一致，而HE染色较PAS法能更有助于清晰、完整、准确地识别PGC的细胞内部结构特征；②在孵化26小时的鸡胚胚外胚盘的明暗交界处可见血岛的发生，血岛发生的时间比真正的卵黄囊产生时间（大约44-48小时）要早很多；③血岛周围的血管内皮细胞与管腔中游离细胞都来自PGC。

The vertical transmission routes of HBV through blastoderm in gestation, trauma or aspiration of amniotic fluid during delivery and milk feeding after birth have been documented.

目前已经清楚的母婴垂直传播途径有；①妊娠时经胎盘传播；②分娩期外伤或吸入羊水；③分娩后母乳喂养等。

GFP-labeled and non-labeled cells from X blastoderm were large and round with the same characters of morphology. The GFP protein was not expressed in CEF cell .Our results suggested that the CVH promoter regions have specific activity in stage X blastoderm.

实验结果显示：在胚盘细胞转染后12 h可观测到绿色荧光表达，转染后24 h荧光细胞增多，细胞形态均呈圆形、体积较大；在鸡胚成纤维细胞未检测到GFP表达。

Although Pygo expressed ubiquitously in the embryo, it expressed at relatively high level in pre-blastoderm embryos which indicated a high degree of maternally provided message, followed by a low level of ubiquitous zygotic expression.

结果表明，虽然pygo普遍表达于整个胚胎中，并且在果蝇胚胎发生全过程都有，但Pygo在前囊胚层(pre-blastoderm)中的表达水平相对较高，这说明胚胎发生过程中来自母方的贡献较高。

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。
