皮层颗粒

卵黄体含蛋白质和糖元，皮层颗粒富含多糖类；

The yolk body contained proteins and glycogen , and the cortical granule was rich in polysaccharide .

以皮层颗粒（CG）单层分布于质膜下做为卵母细胞质成熟的指标，利用CG荧光染色法，研究了不同类型牛卵母细胞的质成熟情况。

Cortical granules ( CG ) fluorescent staining was used to investigate the cytoplasmic maturation ( CM ) in bovine oocytes . The monolayer distribution of CG beneath the oolemma was considered as the criterion of CM .

而且，各种对虾卵子内皮质棒及皮层颗粒的形态结构、活化过程各有不同。本文就中国对虾卵子的活化及卵裂过程进行了激光扫描共聚焦显微镜（LSCM）研究。

The oocyte activation process and cleavage of Penaeus chinensis were studied using laser scanning confocal microscope ( LSCM ) .

左右两侧体动基列间有无色点状皮层颗粒。

Colourless dotlike cortical granules distributed between ciliary rows on both sides .

经过受精刺激之后，葡萄糖-6-磷酸脱氢酶被从内质网和皮层颗粒中释放出来。

After fertilization , G6PDH is released from endoplasmic reticulum and cortical granules .

研究发现，在未受精的卵细胞中，葡萄糖-6-磷酸脱氢酶主要堆积于皮层颗粒内或附着于内质网膜上。

Data shows that : the G6PDH is accumulated in cortical granules and bounded in endoplasmic membranes in unfertilized eggs .

皮层颗粒为圆形，直径0.2～0.4μm，外包一层膜，电子密度大。

Cortical granules are round with a diameter of 0.2 & 0.4 μ m. They are wrapped up in a membrane . Their electron density is high .

皮层内含有皮层颗粒。

The cortex posses cortical granules .

卵黄充满时相：形成皮层泡，卵黄颗粒迅速积累，其数目增多、体积增大，核膜逐渐消失，核仁数目增多、但体积减小，放射膜均匀、放射纹明显，滤泡细胞形成多层扁平滤泡层。

The phrase of yolk filled : cortical alveoli appeared in oocytes , yolk granules accumulated rapidly and its number and volume increased , nuclear membrane disappeared gradually , the number of nucleolus increased but its volume is reduced and so on .

相同的表达趋势也存在于大鼠胚胎脑皮层原代培养神经元中，且mir-34a高表达主要集中在皮层颗粒细胞和锥体神经元（Ⅱ/Ⅲ层）。

Correspondingly , the same trend was found in the primary cultures of rat cortical neurons . Furthermore , high level expression of miR-34a was found in the external granular layer and outer pyramidal layer ( II / III layers ) .
