胚层

Metabolic activity quickly develops in the cells of the embryo and the aleurone layer .

胚细胞和糊粉层中的代谢活性立即活跃起来。

Because of its production of raw materials is not all fine flour, but a mixture of wheat flour has been milled down the process of the cortex, germ, aleurone layer and a small amount ...

由于其制作的原料并不全是精面粉，而是混合了小麦在磨粉过程中被碾下来的皮层、胚芽、糊粉层及少量。。。

Most angiosperm ovules possess two integuments, while gymnosperms usually have only one.

大多数被子植物的胚珠有两层珠被，而裸子植物通常只有一层。

After implantation of the blastocyst in the uterine wall the trophoblast divides into two layers, the chorion and the placenta.

在胚泡植入子宫壁后，胚胎滋养层分成两层，即绒毛膜和胎盘。

Differentiation of the protoderm layer marked the beginning of the structural differentiation in globular stage.

球形胚时期表皮原层的分化标志着体细胞胚结构分化的开始。

Firstly, it is found that there are many obvious differences between Acorus and Araceae. Their differences are based on many aspects which include characteristics of morphology, anatomy and epidermis of leaf, types of tapetum in anther walls , patterns of endothecial thickenings, and ways of development of endosperms, presence or absence of perisperm, components of photochemistry, and sequences of rbcL.

研究表明：1。菖蒲属与天南星科其它属在叶的形态、结构、表面特征，花药绒毡层类型，药室内壁增厚的特点，胚乳的发育方式，外胚乳的有无，植物化学成分，rbcL基因序列等多方面存在着显著的差异。

The optimum work concentration of the indirect ELISA for detecting and screening positive hybridoma cells was established by research again and again. Polystyrene microtitration plates were coated with the purified DHV antigen at the amount of 0.5μg/well.

对鸡胚和鸭胚增殖的尿囊液病毒用反复冻融、氯仿处理、0.22μm滤膜过滤、PEG反透析浓缩以及Sephadex G-200分子筛层析的方法进行纯化，并以此来包被酶标板以及进行BALB/c小鼠免疫，效果良好。

Results The expression of endogenous LN was found in the basement membrane of epithelium, glands and blood vessels in uterine endometrium of both estrus and early pregnancy. And its was faint that LN present in basement membrane as the implantation occurs, but the LN immunostaining in the epithelial cells of endometrium was stronger. The exogenous LN has no obvious influence on blastocyst attachment and implantation. LN-antibody intra-uterine injection showed significant repressing effect on mouse blastocyst implantation.

结果 动情期及妊娠早期小鼠子宫内膜内源性LN在上皮和腺基膜及血管内皮基膜均有表达，并随着植入的发生基膜的LN表达减弱，而内膜上皮中LN免疫染色逐渐增强；外源性LN对小鼠胚泡粘附与植入子宫内膜不产生明显影响，层粘连蛋白抗体明显抑制小鼠胚泡着床。

The scientist has made a pointed comparison between suspensors of plant embryos and mammalian trophoblasts.

这位科学家把植物胚的胚柄与哺乳动物的滋养层做了直接的比较。

In this study, in utero transfection plasmid DNA method was set up to embryonic mouse. The GFP expression vector pCAGGS-IRES-EGFP was microinjected into the lateral cerebral ventricle of E 14.5d mouse embryos through the uterine wall. Then, the 30 V square-wave pulse was delivered across the head for 5 times and interval 50m sec by electrodes in parallel with the median raphes.

本研究旨在通过子宫内电穿孔法，建立鼠胚大脑皮层体内基因转移体系：将带有绿色荧光蛋白的表达载体pCAGGS-IRES-EGFP显微注入胚胎期14.5 d的鼠胚侧脑室中，电极沿与脑中缝平行的方向夹持鼠脑，在电压30 V，脉冲时间50 ms，脉冲数5的条件下方波电击，将外源基因转移到室管膜层细胞。

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。
