生殖细胞

Embryonic stem cell has the capability of immortalization and pleuripotent differentiation.

胚胎干细胞源于着床前的囊胚内细胞团或早期胎儿原始生殖细胞的一类未分化的多能性干细胞，具有无限增殖和多能分化的能力。

If each human family were dependent only on its own resources; if the children of improvident parents starved to death; if, thus, overbreeding brought its own "punishment" to the germ line--then there would be no public interest in controlling the breeding of families.

如果每个人类家庭都是依赖本身的资源；如果眼光短浅父母的子女饥饿致死；如果过度生育为生殖细胞带来自我的「惩罚」—那么管制家庭生育是不涉公共利益。

In particular, it has remained unclear how oogamy arose from isogamy, a more simple form of sex in which ery similar reproductie cells take on different "mating types" but do not differentiate as distinct sperm and egg.

尤其是异配生殖如何由同配生殖转化而来，我们对此还懵懵懂懂。同配生殖是一种更为简单的结合形式，在此过程中，非常相似的生殖细胞不管三七二十一地就与不同的配子结合，都不分这些配子是"公"是"母"。

We believe that the above experiments can help us to understand the genes associated with germ cell development and the function of FANC L in testis.

通过以上实验，我们相信将提高我们对生殖细胞发育相关的多个基因及FANC L在生殖系统中作用的认识。

The generative cell contains a few plastids immediately after the microspore mitosis in L.

在生殖细胞的发育过程中，线粒体的DNA也很快降解。

If an affected child is born to clinically unaffected parents, it is likely that the child has a de novo mutation, and the risk to sibs is far less than 50% but above the population risk because of reported cases of somatic and germline mosaicism.

如果临床无症状的父母但下患病儿童，很可能这个儿童发生了新生突变，而患儿的兄弟姐妹患病的风险远比50％小得多，但比普通人群风险高因为曾报道过体细胞和生殖细胞嵌合体的案例。

In most multicellular eukaryotes, telomerase is only active in germ cells.

在大多数多细胞真核生物中，端粒只在生殖细胞中有活性。

Fc-vasa mRNAs were detected by RT-PCR in early developmental stages from 2-cells embry to intramembranous nauplius, and not in any stages after nauplius. Based on above results, it is postulated that Fc-vasa is required for germ cell determination and formation of F. chinensis as a maternal component.

但表达量逐渐降低，自出膜后的无节幼体开始检测不到表达信号，根据以上结果推测，Fc-vasa mRNA可能作为母源生殖质成分参与中国明对虾生殖细胞的决定和形成。

Note the difference in size and staining quality of the neoplastic nests of cells compared to normal germ cells.

肿瘤细胞与正常的生殖细胞相比，大小和着色都不同。

Massive apoptotic events are induced in the mutant gonads, leading to the abolishment of both spermatogenesis and oogenesis.

在Sun1基因剔除的小鼠性腺中，生殖细胞的大量凋亡导致精子发生和卵子发生被完全破坏。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
