细胞核

In many gymnosperms the nuclei divide within the pollen grain to produce a small number of cells (2-40 depending on the group )representing the male prothallus.

在许多裸子植物中，细胞核在花粉粒中分裂以产生少量的细胞（2～40个，取决于不同种类），代表雄性原叶体。

Phosphorus is associated with the protoplasm of the cell nucleus and lack of it retards cell division and plant development.

磷素与细胞核原生质有关，所以缺磷势必影响细胞分裂和植物的发育。

Phosphorus is associated with the protoplasm of the cell nucleus and lack of it retard s cell division and plant development.

磷素与细胞核原生质有关，所以缺磷势必影响细胞分裂和植物的发育。

"The union of nuclei within and arising from a single cell, as in certain protozoan s and fungi."

某些原生动物或真菌中发生于或在单个细胞内细胞核的接合作用。

Polyethylene glycol (MW6000 35%)-Ca〓(40mmol/l) system was applied to research on the fusion of nuclei and anucleated protoplasts which were deactivated by ultraviolet rays. The fusion process was verified by -dCTP radioisotope tracing with radioautography.

选择PEG6000促融，40mmol/1Ca〓进行了K氏酵母细胞核与His酵母经紫外线灭活的无核原生质体融合的研究，利用放射性同位素dCTP的示踪结合放射自显影技术，对融合进行检测，证实了融合的确实发生。

There was a strong correlation between rCBV and rCBF (spearman's rank correlation coefficient=0.772, p＜0.001). 2 None of the normal brain tissue exhibited NF-κB p65 protein.

30例胶质瘤中17例NF-κB p65蛋白表达阳性，阳性表达率为56.7％，阳性产物定位于肿瘤细胞核。10例正常脑组织中NF-κB p65无1例阳性表达。

At the very start of the pathway, there is also signaling from Ras to Rac.

另一种可能性就是，在ERK转移到细胞核之前长期活化是必需的。

There was high similarity in Sphericity, elips degree and regular form factor among the nucleus of mantle cell-centrocyte-centroblastic-centroblastic lymphoma.

套细胞-中心母细胞-中心细胞-中心母细胞性淋巴瘤细胞的细胞核在圆球度、规化形状因子和椭圆度等参数上具有较大的相似性。

The stem was cut into several segments away from the pine seeding, arranged and collected in the order of chronology time and distance from where they were inoculated. To separate B.xylophilus coarsely out from the stems and made them into paraffin slices. And be observed under the potics microscope by dyed with safranin-fast green contrast-stain method and PI fluorescence stain method. In order to find out how about the nematode rigour distributing , but also ebb and flow of their amounts after invading the host pine seeding. Seek the pathological changing orderliness of host cells in different position along with the remotion of nematodes. By deeply analysing the variety of host cell nucleolus to estimate whether the host cell took place the programmed cell death after inoculated B.xylophilus.

按时间进程和与接种点上下距离的远近，对松苗分茎段进行粗分离和制作成石蜡切片，分别用番红-固绿双重染色法和碘化丙锭荧光染色法在光学显微镜下观察，以了解线虫侵染后在寄主体内的准确分布和数量的消长，寻找随着线虫的移动扩散，寄主不同部位细胞病变的数量、速度发生的变化规律，并进一步通过分析其细胞核的变化来判定松材线虫侵染后是否能诱发寄主细胞发生程序性死亡(programmed cell death，PCD)。

These were low-differentiated cells. Growth curve of cultured MSCs was "S" shape. The first, third and fifth passage cells had strong reproductive capability.

透射电镜观察显示间充质干细胞核大，以圆形或类圆形为主，胞核比例大，细胞器少，为低分化细胞。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
