母核

The effect of EGF on the maturation of oocyte nuclear and cytoplasm is studied by adding EGF in culture media in vitro. In addition, it is also examined by parthenogenetic activation.

本试验在体外成熟培养液中添加EGF，研究其对核及质成熟的作用，并通过孤雌激活来检验EGF对牛卵母细胞胞质的成熟。

Icrofilaments were mainly distributed in the cortex area which chromosomes located at mataphase of second meiosisand concentrated around pronuclei after pronuclear formation.

II 期卵母细胞微丝主要集中在染色体所在的皮层区域，原核形成后微丝绕核重新聚集。

In male, three kinds of sex steroid receptors were distributed in the spermatogonia, spermatocytes and spermatids, and the positive reaction was localized in the cytoplasm and nucleus of these spermatogenic cells.

在雄性，3种类固醇激素受体分布在不同发育时期的精原细胞、精母细胞和精子细胞中，受体阳性物定位在胞质和核。

SHRIMP U-Pb concordia ages of the cores of rounded zircons are 620 and 219 Ma, suggesting that the parental magma for the quartz diorite porphyry may have been derived from partial melting of basement materials of the South China block that had been modified by ultrahigh-pressure metamorphism.

具有细微震荡环带岩浆锆石的SHRIMP U-Pb年龄(117.7±1.6 Ma)显示该石英闪长斑岩体的形成时间为早白垩世；浑圆状锆石核部SHRIMP U-Pb谐和年龄为620 Ma和219 Ma，这表明该石英闪长斑岩的母岩浆可能起源于经历了超高压变质作用改造的华南地块基底物质的部分熔融。

DNA fluorescence dye Hoechest 33342 was used tomonitor the condensation of chromatin during germinal vesicle breakdown.

采用直接取核法获取卵母细胞生发泡，用同步化的HeLa细胞裂解液构建非细胞体系，将游离的生发泡培养在裂解液中，并加入荧光染料Hoechest 33342，观察染色质的变化情况。

A distincitve feature of these blasts is a linear red "Auer rod" composed of crystallized granules.

非常大的、多核的、未成熟的髓母细胞，这些细胞中可见典型的线性红色Auer小体。

A group of genetically identical cells descended from a single common ancestor, such as a bacterial colony whose members arose from a single original cell as a result of binary fission.

无性系由一共同母体而繁生的一群遗传因子完全相同的细胞，例如一菌落的成员来源于二分核分裂的单一母细胞

However Feng et al (1997) and Wakayama et al (1997, 1998) have first reported that followed by injection of PbI into the enucleated oocyte, which was injected into the head of sperm, and the recombinant oocyte could produce a mouse offspring with generational function.

然而，Feng等（1997），Wakayama 等（1997、1998）的研究结果证实：将PbI注入去核卵母细胞后再注入精子头部可以产生具有生殖功能的小鼠后代。

This brought fixed cost, but it also is meant at the same time use a source to won't make you singlehanded assume a problem.

这带来了一定的成本，但它同时也意味着使用开源不会让你独力承担问题。
