细胞分裂

A core needle biopsy misdiagnosed PASH in 13 cases out of 28 cases and vacuum-assisted biopsy correctly identified PASH in all 3 cases.

4细胞性纤维腺瘤和囊肉瘤：PASH缺乏真正的间叶细胞过生长的现象，其细胞缺乏多形性，无核分裂象，也没有纤维腺瘤或囊肉瘤的上皮成分的生长类型。

The extracellular edelfosine promoted the phosphatization of Spmlvia inducing the expression of Mid2; The intracellular edelfosine increased the phosphatization of Spmlvia inhibiting the expression of Pmp1, and leading the holdback of cytokinesis.

细胞外依地福新诱导Mid2蛋白的表达，从而促进的Spm1磷酸化；细胞内依地福新通过抑制Pmp1蛋白的表达，取消Pmp1蛋白对Spm1的抑制作用，使Spm1的磷酸化程度增加，最终导致粟酒裂殖酵母细胞胞质分裂障碍。

The splitting of the cytoplasm is also restrained therefore they form many multi-core cells. With the reducing of the microfilament the pseudopodium of the cell surface become fewer, shorter and wider.

结果发现，在CB作用下，癌细胞生长受到抑制，细胞计数减少；胞质分裂受到抑制，形成多核细胞；微丝结构减少，细胞表面的伪足变少变短变粗。

F1 hybrid has the morphological feature which is between the male and female parents and shoed strong heterosis, exuberant vitality, late ripe period and low rate of self-fertility. The average chromosome configuration of F1 in PMC MI was 18.58Ⅰ+18.59Ⅱ+0.085Ⅲ+0.028Ⅳ. At anphase Ⅰ in PMC, some laggard chromosomes arranged in equatorial plate. Micronucleus and a lot of abnormal cells can be observed at dyad, tetrad and microspore.

杂种F1形态特征介于双亲之间，具有较强的杂种优势，生长旺盛，熟期晚，自交结实率较低。F1花粉母细胞减数分裂中期Ⅰ平均染色体构型为18.58Ⅰ+18.59Ⅱ+0.085Ⅲ+0.028Ⅳ，PMC后期Ⅰ观察到部分落后染色体排列在赤道板上；二分体、四分体和小孢子时期，细胞内普遍观察到微核，且出现大量异形细胞。

To prevent the uncontrolled cell division leading to self-generated cells in two ways - apoptosis and cell senescence.

细胞防止自身无节制分裂导致生成癌细胞有两种方式--细胞凋亡和细胞衰老。

Previous studies have demonstrated that primary spermatocyte can undergo meiotic divisions in MI oocytes and the resulting embryos can develop to term. However, the success rate is very poor.

已经证明初级精母细胞在显微融入MI卵母细胞后可以完成减数分裂并且产生的胚胎可以发育到期，只是发育率还非常低，作为一种形式的核移植，细胞周期的同步化处理对于胚胎的发育具有重要意义。

These data suggested that the centrin isoforms played different roles in different stages of spermatogenesis. The centrin-1 gene was revealed to be relevant to the centriolar translocation to the posterior pole of cell and the elaboration of flagellum during spermiogenesis, while the centrin-2 and centrin-3 might play roles in spermatogonial mitosis but were not involved in the spermatid differentiation process.

这些结果提示，Centrin同源基因在精子发生的不同阶段发挥不同功能，其中Centrin-1与精子细胞分化期的中心体后移、鞭毛的生成及精子中轴形成可能密切相关，Centrin-2和-3则可能在精原细胞有丝分裂中起作用，而与精子细胞变态分化无关。

Researchs suggested that ceramide and sphingosine could inhibit mitosis and DNA synthesis of cancer cells, promote apop

细胞水平研究发现神经酰胺和鞘氨醇能抑制结肠癌细胞有丝分裂和DNA合成，促进细胞凋亡，影响Fas、Bcl-2、Bcl-10、bax和P53等凋亡相关蛋白的表达，即神经酰胺和鞘氨醇能通过抑制结肠癌细胞生长、促进细胞凋亡发挥抑癌作用。

Based on principle of pollen abortion, utilizing tapetum of anther cell, mitochondria of tapetum, callose well, process of cell meiosis during formation process of pollen, we adopt genetic transformation to create plant male sterility, such as, exogenous cytotoxin gene, chaperones, anti-sense RNA, degradation of callose ahead of time, disturbing information intercommunion between mitochondria and nucleolus and affected development of pollen sporule by bacteria.

根据花粉败育的原理，利用花药细胞绒毡层、绒毡层线粒体、胼胝质壁、细胞减数分裂过程等花粉形成过程中的不同环节，采取外源细胞毒素基因、分子伴侣、反义RNA技术、提早降解胼胝质、扰乱线粒体与细胞核之间的信息交流和细菌影响花粉小孢子发育等策略，使花粉不能正常形成，从而产生不育花粉，达到产生雄性不育的目的。

The juice sac primordium originated from a single cell of the carpel-lary endoepidermis with partial participation of subepidermal cell just belowthe initial cell.

锦橙和温洲蜜柑的汁囊最初是从心皮内表皮的单个细胞发生的，后来原始细胞下面的细胞也发生分裂，部分参与了汁囊原基的形成。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
