We found that TN-C was abundant in the early heart development of rats, it was suggested that TN-C reference to the early heart morphogenesis; TN-X was poorly expressed in epicardium in hearts of ED11.5, implied it may have something to do with the formation of the coronary artery.

TN-C在大鼠胚胎心脏发育早期表达丰富，对心脏的早期发育有一定关系；而TN-X在ED11.5于形成血管的心外膜细胞周围表达，提示TN-X可能与心脏早期冠脉等血管的形成有关。

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。

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。

The research advance on organogenesis, somatic embryogenesis and protoplast regeneration system of soybean are introduced in this paper.

终于在20世纪80年代初期有了转机，人们选择了幼胚、幼胚子叶或胚轴为外植体，用异常高浓度的植物生长调节物质，建立了大豆的体细胞胚胎发生和器官发生再生系统。

Surgical repair of the cleft that ovarian mouth. 2, officials outside the pregnancy growing in the fallopian tube embryos, together with the Ministry of blood into the abdominal cavity by the casual, stimulating the peritoneum, causing acute abdomen; surgery do not touch the ovary, only a section can salpingectomy, ectopic pregnancy on the premise that must be positive pregnancy test.

手术修补卵巢的裂口即口。2、官外孕是在输卵管内生长的胚胎，连同血液经散部流到腹腔，刺激腹膜，引起急腹症；手术不碰卵巢，只把输卵管切除一段即可，宫外孕的前提是必须妊娠试验阳性。

We derived cell populations with properties of ectodermal and mesenchymal cells in 2D culture and incorporated these divergent cell populations into 3D epithelial tissues.

我们利用二维培养将胚胎干细胞分化为具有外胚和间充质特性的细胞，再将这些细胞复合入三维上皮组织。

The sebaceous gland is formed embryologically as an outgrowth from the upper portion of the hair follicle.

从胚胎学上来说，皮脂腺是从毛囊上部向外生长形成的。

We evaluated 350 tumors: 136 ES, including 64 conventional ES, 64 proximal-type ES, and 8 with hybrid features of conventional and proximal-type ES; 54 metastatic carcinomas (22 from lung, 6 breast, 6 stomach, 5 colorectum, 5 kidney, 5 prostate, 5 pancreas); 12 metastatic testicular embryonal carcinomas; 20 metastatic melanomas; 20 epithelioid mesotheliomas; 20 epithelioid angiosarcomas; 10 epithelioid hemangioendotheliomas; 24 epithelioid malignant peripheral nerve sheath tumors; 22 myoepithelial carcinomas of soft tissue; 7 anaplastic large cell lymphomas; 5 histiocytic sarcomas; and 10 control MRT of infancy (4 brain, 3 liver, 2 soft tissue, 1 kidney).

我们总共研究了350例肿瘤：136例ES，其中包括64例寻常型ES、64例近端型ES和8例混有前两型特征的混合型ES；54例转移癌（22例来自肺、6例来自乳腺、6例来自胃、5例来自结直肠、5例来着肾、5例来着前列腺、5例来着胰腺）；12例转移性睾丸胚胎性癌；20例转移性黑色素瘤；20例上皮样间皮瘤；20例上皮样血管肉瘤；10例上皮样血管内皮瘤；24例上皮样恶性外周神经鞘膜瘤；22例软组织的肌上皮癌；7例间变性大细胞淋巴瘤；5例组织细胞肉瘤；10例作为对照的婴幼儿MRT（4例位于脑、3例位于肝、2例位于软组织、1例位于肾）。

T lymphocyte percentages of peripheral blood, lymph node, spleen, thymus and bone marrow of maters of interspecific, intraspecific embryo implantation and pseudopregnant mice at corresponding time were measured using fluorescence labeled monoclonal antibody and flow cytometry.

利用荧光标记的单克隆抗体染色结合流式细胞术，检测种间、同种胚胎移植以及同时期假孕母体外周血、淋巴结、脾脏、胸腺、骨髓中T淋巴细胞的百分率。

BACKGROUND: The HOX gene family is a highly conserved transcription factor family, which affects the formation of basic axis and secondary axis during embryonic development, at the same time, it plays a pivotal role in the development of the central nervous system, axial skeleton, stomach intestine, urogenital system and external genitalia.

背景：HOX基因家族是一个高度保守的转录因子家族，该家族在胚胎发育阶段基本体轴和次级体轴的形成中起作用，同时在中枢神经系统、中轴骨、胃肠和泌尿生殖系及外生殖器和肢体的发育中起重要作用。

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
