胚胎

The third and final excretory organ that develops in a vertebrate embryo.

后肾脊椎动物胚胎发育中的第三个也是最后一个排泄器官。

We can not find any known domains in BEX1, but we notice that the C-terminus of it is similar to p75NTR-associated cell death executer, which is also highly expressed in brain and X-link. It may be a signaling adaptor molecule involved in p75NTR-apoptosis induced by nerve growth factor.

已有文献报道，在小鼠植入前的胚胎发育过程中Bex1基因在转录水平表达量发生变化，在出生后睾丸的发育过程中表达也有差异，说明这个基因与小鼠的发育相关。

The research on our ancestors'inner world reflected by the Five Classics. is also a process of exhumation on people's inner world today.

通过五经对先民精神世界的反映的探寻，也是一种对今人精神世界胚胎的发掘。

Based on the above results, we can conclude that Mist1 functions in an evolutionary conserved way as a key transcriptional regulator specific for exocrine pancreas development in zebrafish. In addition, it is involved in the embryonic CNS development, and even earlier initial period of development.

根据以上结果可以得出结论，Mist1作为转录因子，以一种进化保守的方式特异性调控斑马鱼外分泌胰腺的发育；另外，它还在斑马鱼胚胎早期发育过程中参与了中枢神经系统的发育，以及更早的发育起始过程。

Here, we demonstrate that Tsix transcriptionally silences Xist in both embryonic and extraembryonic tissues of mouse embryos.

这里，我们证明Tsix基因可以在胚胎和胚外组织中在转录水平上沉默Xist基因的表达。

It includes the embryo or the fetus as well as the extraembryonic membranes.

胚胎从受精到出生期间任一阶段产物的通称，它包括了合子或胎儿甚至胚胎膜

The embryos of land vertebrates are enclosed within four extraembryonic membranes that afford protection while still permitting the exchange of gases, nutrients, and other materials.

脊椎动物的胚胎被4层膜包被，起保护作用，但仍能交换气体，营养和其他物质。

Xist and Tsix are imprinted in the extraembryonic tissues of mouse embryos so that they are expressed from the paternal and maternal X, respectively, resulting in the preferential inactivation of the paternal X.

Xist和Tsix在小鼠胚胎的胚外组织中是印迹的，Xist在父本X染色体上表达而Tsix在母本X染色体上表达，导致父本X染色体的优先失活。

Embryonic Coverings and Membranes The embryos of land vertebrates are enclosed within four extraembryonic membranes that afford protection while still permitting the exchange of gases nutrients and other materials.

脊椎动物的胚胎被4层膜包被，起保护作用，但仍能交换气体，营养和其他物质。

The embryonic vessels failed to invade into the labyrinthine layer of placenta, which impaired the embryonic-maternal vascular connection. These defects could not be rescued by wild-type tetraploid blastocysts, excluding the possibility that they were due to the extraembryonic tissues.

组织免疫组化分析结果显示：毛细血管腔异常扩张，排列紊乱，不能形成大血管及细致有序的血管网络；胚外中胚层来源的卵黄囊脏层扁平上皮细胞形态变圆，与内皮细胞连接受损；胚胎血管不能侵入胎盘迷路层，胚体与母体血管连接受损。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.

这是凯特，那个是爱朗。
