查询词典 somatic effect

He number of TCR V(Vα equal s to 100 and Bβ equals to 30 ) is less than the one of lg Vh (Vh equals to 300),for TCR V is subject to negative selection of major histocompatibility complex according to the neutral theory We discussed that is somatic mutation or DNA rea rrangement the main force in producing antibody diversity and are there pseudoge nes in TCR V or not.

CR V的数目(V α为100，Vβ为30)远少于Ig VH(数目为300)，原因是前者受到主要组织相容性复合体的制约，即受到负选择，这与中性学说观点相一致。文章还讨论了体细胞突变和DNA重排对两类抗体多样性产生上的作用，并探讨了Ig VH和TCR V的假基因问题。关键词分子进化，协同进化，免疫球蛋白，T细胞受体，中性学说

Aneuploidy The condition, resulting from nondisjunction of homologous chromosomes at meiosis, in which one or more chromosomes are missing from or added to the normal somatic chromosome number.

非整倍性：在减数分裂的过程中同源染色体不分离而造成的一条或多条染色体的缺失或增加。

细胞核移植技术不仅是研究细胞核与细胞质相互作用的重要手段，而且是在医学和农业等领域都将有着广泛的应用前景的一项重要胚胎工程技术。

Besides, combined with the somatic cell nuclear transfer technique, MMCT has been employed for producing transchromosomic animals of medical and agricultural value. It will have extensive application in the future.

与体细胞核移植技术结合，MMCT还可用于建立具有重要医学药用价值和优良农业生产性状的转染色体动物，显示其具有广阔的应用前景。

Scores of dogs have been cloned using so-called somatic cell nuclear transfer, a technique for hollowing out the nucleus of a donor egg and injecting it with the donor's genetic material, which is typically skin tissue taken from the ear.

许多犬只的复制是利用所谓体细胞核转植的技术，这种技术将捐赠卵子中的细胞核挖出，再注入由捐赠犬只身上取出的遗传物质，通常是它们耳朵的皮肤组织。

Recently generated ESC-like pluripotent cells by reprogramming somatic cells, named induced pluripotent stem cells, open a new gate for cell transplantation-based regenerative medicine.

经体细胞重编程产生的诱导多能干细胞(induced pluripotent stem cells， iPS)也被证明有类似胚胎干细胞的特性。

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。

These observations show that reprogramming is easier in interspecific embryos reconstructed with ES cells than that reconstructed with somatic cells, and that ES cells have the higher ability to direct the reconstructed embryo development normally than fibroblast cells. Oocytes were reconstructed with outbreeding Kunming albino mouse ES cells and enucleated rabbit oocytes, and the effects of the passages of ES cells and 6-DMAP on the development of interspecific reconstructed oocytes were analyzed. The interspecific reconstructed ES-rabbit oocytes were activated either by combined two set electric pulses and 6-DMAP or by two set electr

以上结果显示，6－DMAP能增加胚胎干细胞异种重构卵的卵裂率，对重构卵囊胚的发育率影响不大；高培养代数和低培养代数的胚胎干细胞用于异种核移植不影响异种重构卵的卵裂率和囊胚发育率；用胚胎干细胞作为供核细胞；比体细胞作为供核细胞所构建的异种重构胚更容易进行重编程，并且胚胎于细胞指导异种克隆胚胎正常发育的能力强于体细胞。
