The team found that coat color apparently depends on the degree to which astretch of regulatory DNA just upstream from a gene controlling coat color,called agouti,is methylated.

Surani和其它研究者认为，成体动物获得的特异突变传给下一代的可能性大大地为生殖细胞在生命的早期就被隔离开来的事实所限制。

An experiment was performed to compare effect of different cell media on embryonic germ cells derived from primordial germ ridge of Kunming albinotic strain mouse.

以昆明白品系小鼠胎儿生殖嵴为材料，以不同的培养液分离培养胚胎生殖细胞，发现小鼠胎儿肝细胞条件培养液的效果好于未添加白血病抑制因子的基础培养液，而差于添加了1 000 IU/mL LIF的基础培养液。

Above results suggest that the nuclear genes controlling amyloplast development may express in the uninuclear microspore and continue to be active in the VC, while the genes controlling plastid dedifferentiation may be promoted in the GC after the first mitotic division.

以上结果表明可能控制造粉质体的核基因在单核小孢子中表达并继续在营养细胞中起作用，而控制质体脱分化的基因在第一次有丝分裂后才在生殖细胞中被启动。

The gonadal development in aneuploid is similar to that of triploids and can produce mature gametes.

非整倍体牡蛎的性腺发育情况与三倍体个体相当，也能产生成熟的生殖细胞。

It is motile and is produced in an antheridium, except in certain gymnosperms (e.g.Cycas, Ginkgo) in which antherozoids develop from the generative cells of the pollen tube.

除了在一些由花粉管的生殖细胞产生配子的裸子植物中（铁树 Cycas，银杏 Ginkgo ），通常是由精子器产生的并且会游动。

Cancer of ovarian and transparent cell is most constant tumour of as epithelial as the ovarian surface of confuse of interblend of tumour of cell of the former reproduction that send a gender sex, especially with yolk bursa tumour and asexuality cell tumour are differentiated harder.

梗概： 卵巢透明细胞癌是最常和原发性生殖细胞肿瘤相混淆的卵巢表面上皮性肿瘤，尤其和卵黄囊瘤和无性细胞瘤较难鉴别。

Methods: The hEGcs from the gonadal ridges and dorsal mesenteries of human embryos aged 5-10 weeks were cultured with or without cytokine in culture medium to observe their growth and the effects of different cell culture systems were compared.

目的：优化人胚胎生殖细胞的体外培养体系，并将生长状态良好的传代的人EG细胞移植用于大鼠心肌梗死模型的治疗，探讨人胚胎生殖细胞进行异种移植对大鼠心肌梗死的治疗机制。

The Piwi clade is found in all animals examined so far, and its presence is tightly correlated with the emergence of specialized germ cells. Most animals separate germline and somatic cells early in development and restrict Piwi expression specifically to germ cells.

Piwi蛋白迄今为止被发现存在于所有动物中，它的存在与专门的生殖细胞紧密相关，大多数动物在发育的早期开始了不同组织和体细胞的分离和分化，并且对于生殖细胞的Piwi蛋白的表达进行特别的限制。

During two-celled pollen grain stage, they were accumulated on the wall of the generative cell. After the generative cell came into the vegetative cell, ppts largely disappeared.

二胞花粉刚形成的生殖细胞表面呈现大量的ATPase反应颗粒，当生殖细胞脱离花粉内壁移入营养细胞，ATPase反应颗粒基本消失。

In this study a germ-somatic cell coculture model of 18-day-old chicken embryo ovarian cells was established to evaluate effects of follicle-stimulating hormone and 17β-estradiol (E2) alone or in combination on germ cell proliferation.

本实验建立了鸡胚（18日胚龄）卵巢构建生殖细胞和体细胞的共培养模型，并研究卵泡刺激素、17β雌二醇(E2)以及二者联合处理对生殖细胞增殖的影响。

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。
