The depth of tectal layerⅠand the morphological characteristics of tectal cells in layerⅠwas investigated using Nissle staining, Golgi staining, and postmortem labeled with DiImethod. Most ofⅠcells appeared shuttle, others showed round, oval, pyramidal, triangular,and polygonal etc. The lateral region of layerⅠwas thicker than the ventral and the dorsalregions.

本研究使用Golgi-Cox法，灌流固定后尼氏体染色、羰花青荧光染料DiI(1，1′-dioctadecyl-3，3，3′，3′-tetramethylindocarbo-cyanine perchlorate)逆向神经标记技术，对雏鸡视顶盖Ⅰ层的厚度和该层的细胞形态、大小进行了观察研究和数理统计，并对不同日龄鸡胚的Ⅰ层厚度进行了数理统计及分析研究。

Somatic embryogenesis is a remarkable illustration of plant totipotency,and under appropriate culture medium can develop to an adult plant with high frequency, so it is a excellent system for genetic improvement.

植物体细胞胚发生是植物细胞全能性的重要体现，在适宜的培养条件下能够以较高的频率再生出完整的植株，是植物遗传改良受体系统。

Methods DNA aneuploid and TA were detected respectively in 165 cases of malignant pleural effusion and 127 cases of benign dropsy of chest (benign group, including tuberculous,other effusion and transudate of chest) by FCM and TRAPHybELISA.Carcinoembryonic antigen was also detected in the two groups.The difference of DNA aneuploid and TA between these two groups was analyzed.

恶性积液165份、良性积液127份(包括结核性、其他渗出液、漏出液)，应用流式细胞术检测DNA异倍体、端粒末端重复序列扩增—杂交—酶联免疫分析技术检测TA，同时检测临床常用的癌胚抗原，比较各类积液中上述3项指标检测结果的差异。

The triphasic nature of Wilms Tumor is obious here.

Wilms'瘤也称作肾母细胞瘤，是由肾胚芽组织发生的恶性混合型肿瘤，最常见于2～4岁小儿，多单侧发病。

Results The olfactory ensheathing cells from human fetal olfactory mucosa were positive for P75 and GFAP, and in in vitro culture, the cells exhibited dipolar or tripolar appearance with long thin neurites. On the 9th day of cell culture, the purity of the olfactory ensheathing cells reached about 83%.

结果 人胚嗅粘膜嗅鞘细胞形态多呈双极、三极，伴有细长的突起。p75和GFAP染色均呈阳性反应，体外培养9d时纯度可达83%。

Recombinant endostatin is a specific inhibitor of chick chorioallantoic membrane angiogenesis and human vitelline vein endothelial cell ECV-304 proliferation. The recombinant endostatin regressed established syngeneic B16 melanoma tumor in mice.

重组内皮抑素能够抑制鸡胚尿囊膜血管生成和人脐静脉内皮细胞ECV-304的增殖，在小鼠体内实验中对黑色素瘤产生良好的抑瘤效果（P＜0.01）。

Using homolog from other species. The membrane localized MSBP1 was characterized as a negative

同源基因。其中膜定位的MSBP1 是一个细胞伸长的抑制因子，它的过量表达植株下胚轴变短

In this study,Using extracted total DNA from duck plague virus vaccine strain infected Chicken embryo fibroblasts cells as template, the 1.0 kb TK gene nonessential for viral replication was amplified by polymerise chain reaction and cloned into T-easy vector to obtain pGTK.

本研究从感染鸡胚成纤维细胞的鸭瘟病毒疫苗毒株中提取了总DNA，并以此为模板，利用PCR技术扩增出病毒生长非必需的TK基因(约1.1kb)，将其克隆入pGEM-T easy载体获得载体pGTK。

Mouse embryonic stem cells are pluripotent cell lines isolated from the inner cell mass of blastulas which can proliferate unlimitedly and have ability of self-renewal.

中国农业科学院，动物遗传育种与繁殖，2009年，博士 \'胚胎干细胞是从囊胚内细胞团分离出来的，具有无限增殖、自我更新的能力。

Howeer, at least one group has made it to the first step--creating a human blastocyst by inserting the nucleus of an adult skin cell into an enucleated oocyte Science, 28 April, p.

然而，至少有一个研究小组已经走出了第一步，通过将一枚**皮肤细胞的细胞核植入一枚去核的卵细胞培育了一个人类胚泡（科学，4月28日，516页）。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
