In mouse, the position of first polar body (PB1) and MⅡ nucleus or spindle is moveable and thus it is difficult to enucleate beneath the PB1. In this study, the 3% sucrose treatment was prepared for enucleation.

在小鼠的卵母细胞中，第一极体（PB1）与MⅡ期核或纺缍体的位置是不固定的，因此导致了去核的困难。

The polar and egg nuclei of the female gametophyte are genetically identical.

雌配子体中的极核和卵核遗传上是同一的。

Two polar nuclei move to the micropylar end before sperm is released in a gap between the egg cell and central cell and subsequently taking off cytoplasm one after another. The sperm nucleus moving to the egg nucleus runs faster than the one to the polar nuclei. It fuses with the polar nuclei that are moving towards the antipodal cells at the chalazal end.

精子释放前，两极核移向卵细胞的合点端；两精子释放于卵细胞与中央细胞的间隙后，先后脱去细胞质，然后分别移向卵核和极核，移向卵核的精核快于移向极核的精核；精核与两极核在向反足细胞团方向移动的过程中完成雌雄核融合。

Two polar nuclei move to the micropylar end before sperm is released in a gap between the egg cell and central cell and subsequently taking off cytoplasm one after another. The sperm nucleus moving to the egg nucleus runs faster than the one to the polar nuclei. It fuses with the polar nuclei that are moving towards the antipodal cells at the chalazal end, Images showed the fusion process of male and female nuclei and polyspermous fertilization.

精子释放前，两极核移向卵细胞的合点端；两精子释放于卵细胞与中央细胞的间隙后，先后脱去细胞质，然后分别移向卵核和极核，移向卵核的精核快于移向极核的精核；精核与两极核在向反足细胞团方向移动的过程中完成雌雄核融合。

The cloning of mammals by somatic cell nuclear transfer requires epigenetic reprogramming of the differentiated state of donor cell to a totipotent, embryonic ground state.

由于供体核支持整个克隆动物的发育，所以当供体核被移入去核的卵母细胞后，必需进行重编程，回到胚胎发育的起始阶段。

Enucleated metaphase Ⅱ oocyte can support reprogramming of transferred nucleus and further development to term.

许多实验证明去核的MⅡ期卵母细胞可支持移入的核进行重新编程并发育到出生。

Donor cells in manipulation medium contain of 7% ethanol prior to injection were injected directly to enucleated cytoplasts.

供核细胞注核前置于含7％乙醇的操作液中，然后直接注入到去核的卵母细胞质内。

Rachis, pedicels, and hypanthium abaxially pubescent; fruit red or orangish red, obovoid, ovoid, or subglobose, with 2–5 pyrenes.

Rachis，花梗和托杯背面具短柔毛；橙黄红色，倒卵球形，卵球形的果红色或，或近球形，具2-5果核。

Inflorescence 3–11-flowered; petals white; leaf blade ovate-lanceolate to oblong-ovate, abaxially sparsely tomentose; fruit subglobose, with 5 pyrenes.

花序3-11花；花瓣白色卵形披针形叶片卵形的到长圆形，背面稀疏被绒毛；果近球形，具果核。 22 C。 glomerulatus 球花栒子

However, when two maturing oocytes fused and two spindle will form in the big cell, the chromosomes will not intermingle. In the present study, we removed GV from one oocyte and transfer to the perivetelline space of another GV oocyte. After fusion the resulting oocytes which contained two GVs were cultured further in MEM.

在本实验中，我们利用小鼠GV期卵母细胞将一枚卵母细胞的生发泡取出后移至另一未经去核处理的GV期卵母细胞透明带下，经三次电脉冲作用后将融合的含有两个GV的卵母细胞放入MEM成熟培养液中培养，在培养成熟的不同阶段分别收集卵母细胞进行免疫荧光染色观察微管及核的变化。

与卵核的相关的网络解释 [注：此内容来源于网络，仅供参考]

blastoderm：胚盘

现在来看果蝇(Drosophila)的例子:在果蝇的早期胚胎发育中,最初一些有丝分裂并 不伴有细胞分割.经过几次核分裂后,细胞核移到胚的表面,形成胚盘(blastoderm).其 中少数几个核位于卵后端的极细胞质(pole plasm)中,在这些核的周围立即形成细胞膜,

chorion：卵壳

使卵有一个适宜的生长发育环境.产卵于植物组织.三,卵的基本结构 昆虫的卵是一个大型细胞.最外面是起保护作用的卵壳(chorion),卵壳里面 的簿层称卵黄膜(vitelline membrane)围着原生质,卵黄及核.丰富的卵黄 充塞在原生质网络的空隙内,

egg apparatus：卵器

近珠孔端的三个核,一个分化成卵细胞(egg cell)、两个分化为两个助细胞(synergid),它们常合称为卵器(egg apparatus). 卵器中的这两类细胞在形态、极性和细胞壁的分化上有许多相似之处,彼此间有胞间连丝,协同完成卵的受精过程.

oogonium：藏卵器

进行有性生殖时,部分菌丝细胞分化为雄器(antheridium)和藏卵器(oogonium)两种配子囊,二倍体细胞核在发育的雄器和藏卵器中发生减数分裂,产生单倍体细胞核;雄器和藏卵器先是以配子囊接触交配的方式进行质配,两个单倍体细胞核在藏卵器中进行核配,

oospore：卵孢子

(1)卵孢子(oospore):卵菌的有性孢子. 是由两个异型配子囊--雄器和藏卵器接触后,雄器的细胞质和细胞核经授精管进入藏卵器,与卵球核配,最后受精的卵球发育成厚壁的、双倍体的卵孢子. (2)接合孢子(zygospore):接合菌的有性孢子.
