生殖细胞

Results: 4 cases were geminoma, 3 cases were teratoma, 1 case was choriocarcinoma, 4 cases were glioma, 2 cases were meningiomas, pineoblstoma, neuroblastoma, dermoid cyst and arachnoid cyst each had one case. It maybe very difficult if we diagnosed only through MR signals. Due to the multitude origin of histology, we can diagnose through some special signals, such as adipose, cystic degeneration, hemorrhage and implant dissemination. We can also combined with clinical examination which is help to differential diagnosis.

结果：生殖细胞瘤4例，畸胎瘤3例，1例绒毛膜癌，胶质瘤4例，脑膜瘤2例，松果体母细胞瘤、神经母细胞瘤、皮样囊肿及蛛网膜囊肿各1例，仅通过MR信号较难诊断，由于肿瘤组织学来源多，可通过一些特殊信号如脂肪、囊变、出血、种植播散等，并结合临床检查来进行鉴别诊断。

The results showed that(1) TES accelerated the meiosis and maturity of germ cells in leptotene, zygotene, pachytene, diplotene and diakinesis of prophase 1 of spermatocytes while STI inhibited the meiosis and maturity,(2) there was a significant e...

结果表明：(1)TES对前期Ⅰ5个分期的生殖细胞具有促进细胞分裂和成熟的作用，STI抑制细胞分裂和成熟；(2)TES和STI对前期Ⅰ粗线期药物效应显著；(3)TES和STI在小鼠体内最大有效效应分别持续约计70和50小时。

Relation between localization of nucleus and polar distribution of Con A receptors on surface of central cell and egg cell was also studied.

为进一步探讨由生殖细胞到精子的发育过程中细胞质膜表面凝集素受体的可能变化及两个精子的可能差异。

It has been demonstrated that through the formation of embryoid bodies germ cells can be derived from embryonic stem cells.

当前的研究已经证实了胚胎干细胞能在体外分化出胚性生殖细胞。

Germ potential is established after conception in a totipotent zygote and retained subsequently during development in blastomers of morula , cells form the inner cell mass of blastocyst , epiblast and population of primordial germ cells .

种子潜能的确定是全能的受精卵形成之后，并且随后在桑葚胚，胚泡内层细胞，外胚层和原生殖细胞的发育过程中保留。

ESCs are traditionally regarded as ICM cells, though some scholars believe they are more closely resemble cells from the epiblast. But recent evidence about cell molecular markers indicate that ES cell's characteristics resemble early germ cells.

传统观念常常把ESCs等同于ICM细胞，也有学者认为ESCs更象上胚层细胞，而在已知的分子标记基因方面，ESCs所具有的特征更接近体内早期生殖细胞。

These findings suggest that GSE may associate with meiosis during gametogenesis.

上述的这些结果提示，GSE与配子发生过程中的减数分裂有关，GSE基因主要在哺乳动物生殖细胞的减数分裂中起重要作用。

This study provides genetic evidence that SUN1-telomere interaction is essential for telomere dynamic movement and is required for efficient homologous chromosome pairing/synapsis during mammalian gametogenesis.

我们的研究首次从遗传学上证明了SUN1蛋白和端粒的相互作用对于端粒在动物生殖细胞减数分裂中的动态变化，高效的同源染色体配对、联会以及哺乳动物的配子发生是必不可少的。

Gametogenesis in many kinds of insects, lower vertebrate animals and hibernating animals as well as scrotal mammals depends on a suitable low-temperature condition to generate germ cells and acquire maturation competence thereafter.

通过漫长的进化历程，不同的生物以不同的外界因素作为主要的信息，结合自身内在的节律，决定生殖细胞的发生、成熟和繁殖后代的时序，从而形成一定的生殖周期。

In addition, germ-line epimutations of other tumor suppressor genes, such as MSH2 and BRCA1, have also been reported, demonstrating that epimutations might arise in the germ-line (during gametogenesis or early embryonic development).

随后，关于其他抑癌基因MSH2与BRCA1等的胚系异常甲基化也陆续有报道。这提示，表观突变也可以起源于胚系（生殖细胞形成期或胚胎发育早期），从而造成全身细胞广泛的基因转录沉默。

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。
