Sertoli cell, Leydig cell and germ cell are major cells in mammal testis and they have close relations.

Sertoli细胞、Leydig细胞和精细胞是哺乳动物睾丸内的三种主要的细胞，它们之间关系密切。

Meanwhile, utilizing cells derived from same germ layer to functional replace the original cell types in the defect area has provided a great hint for seeking new cell sources.

而利用发育同源细胞在特定组织为环境下向特定细胞的转变以实现功能上的替代，为寻找种子细胞来源开辟了新的思路。

Here, we show that several maternally derived germ P granule components are selectively eliminated by autophagy in somatic cells during C.

研究人员以秀丽隐杆线虫为模型，在秀丽隐性杆线虫胚胎发生期，未分化的体细胞中含有来自母体的 P 颗粒的部分蛋白被自体吞噬作用清除掉。

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。

The majority (90 percent) of primary ovarian tumors derive from epithelial cells, although they can also arise from germ cell tumors, sex cord-stromal tumors, and mixed cell type tumors.

大多数（90%）原发性卵巢癌来源于上皮细胞，尽管它们也可为源自生殖细胞肿瘤、性索间质肿瘤和混合细胞型肿瘤。

In addition, some biological events, such as separating the male germ unit, providing movement orbits for the two sperm cells and inducing both sperm to synthesis DNA, may also be related to the degenerated synergid.

另外，雄性生殖单位的解体、提供精细胞的运动轨道和启动精细胞合成DNA的生物学事件也可能与助细胞有关。

During the development of dental germ, enamel matrix proteins secreted by epithelial root sheath could induce dental follicle cells to differentiate towards cementoblast and form acellular cementum finally on the surface of tooth root. Many researches of domestic and oversea scholars suggest that enamel matrix proteins could effectively induce periodontal regeneration, and the structure and function of this regenerated tissue are similar to healthy periodontal tissue. Moreover, the regeneration process is nearly the same to that of embryonic development of periodontal tissue.

自发现釉基质蛋白可诱使牙囊细胞向成牙骨质细胞方向分化并在根表面形成无细胞性牙骨质以来，国内外学者做了大量研究，结果表明釉基质蛋白能有效诱导牙周组织的再生，且这种再生组织的结构和功能更接近于健康的牙周组织，并且再生过程也与牙周组织的胚胎发育过程类似。

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。
