滋养层

HBV transplacental transmission route may be realized by cell to cell transfer in placenta, which means that HBVs in maternal blood and/or intervillous space infect DCEC and/or DC and/or TC, then transmit to VMC, then to VCEC, and finally to fetus.

HBV经胎盘感染胎儿的路径可能是通过胎盘细胞至细胞的传递而实现的。即母血和/或绒毛间隙HBV→蜕膜毛细胞管内皮细胞和/或蜕膜细胞和/或滋养层细胞→绒毛间质细胞→绒毛毛细血管内皮细胞→胎儿。

Oct4 plays a critical role in maintaining pluripotency of stem cell when it differentiates into a trophectoderm lineage at early stage of mouse embryo.

在早期鼠胚中，只有在ICM变成滋养层阶段，Oct4为维持其全能表型而发挥作用。

GFP fluorescence was visible early at the 2-cell stage and then became stronger in the blastocysts of all three species. However, the distribution of the GFP signals was restricted to the cells of inner cell mass and no fluorescence was detectable in trophectoderm cells.

结果显示：牛Oct-4启动子驱动的GFP基因在3个物种的2-细胞胚胎就已经开始表达，在囊胚期表达加强且只特异表达于内细胞团中，而不表达于滋养层。

Now TCS is being clinically used in China for abortion and treating trophoblastic tumors.

目前，纯制的天花粉蛋白已在临床上被用作引产和治疗滋养层肿瘤的药物。

While, the cell characteristics have bee n changed in trophoblastic...

此外 ，目前在鉴定分离培养的细胞是否就是滋养层细胞这一关键问题上尚无统一标准

It was expressed on trophoblastic cell, interstitial cell and endothelium cell of interstitial blood vessels of villi.

结果 ①所有的标本绒毛滋养层细胞、绒毛间质细胞、毛细血管内皮细胞都有HAV的存在。

I connect blood cycle with mun, in the trophoderm, my embryo begins to form looks like a plate.

我与妈妈的血液循环建立了联系。在滋养层里，我的胚胎开始成形，现在看起来像个椭圆形的盘子。

Furthermore, preliminary work also performed to examine whether PI3K/AKT signal transduction pathway was activated in the process of refractory leukemia development. Materials and methods An immortalized human bone marrow stromal cell line, HS-5, was introduced to establish a bi-phase culture system for the cultivation of B-lineage precursor leukemia cells. ELISA and RT-PCR were used to investigate the expression of VEGF and its receptors in the leukemia cell lines and primary childhood leukemia cells in different treated groups. Flow cytometory method and immunofluorescent staining were employed to examine the apoptosis signals both in the VP16 treated and untreated leukemia cells. Western blot was utilized to explore the PI3K/AKT activated status in the drug induced or uninduced leukemia cells and lymphocytes from healthy donors.

材料和方法使用来源于人类骨髓基质细胞的细胞株HS-5作为滋养层细胞进行急性淋巴细胞性白血病细胞的体外培养，通过细胞生物学和免疫学方法评估培养体系并鉴定出难治性白血病细胞克隆；以ELISA和RT-PCR方法检测急性白血病细胞株和患儿白血病细胞VEGF及其受体的表达，了解不同治疗阶段VEGF及其受体的表达状况，并结合临床指标进行分析，明确VEGF及其受体在白血病发生过程中的作用；流式细胞仪和免疫荧光染色法对正常健康儿童、初发白血病患儿、复发白血病患儿及缓解后患儿进行凋亡因子检测和分析，初步阐明难治性白血病抗凋亡形成的原因；蛋白印记分析检测PI3K/AKT信号传导通路在健康儿童、初发白血病和复发白血病患儿的表达，初步了解难治性白血病形成的分子生物学机制。

We used the medaka as a fish model for the development of ES cell technology. We have established feeder cell free culture conditions and obtained several ES cell lines from midblastula embryos.

我们以青鱂作为建立鱼类ES细胞技术的模式，通过建立并应用无滋养层细胞的培养条件，获得了来自中期囊胚的ES细胞系。

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。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
