细胞分裂

Finally, cells that only produce identical copies of themselves are called unipotent. Like skin cells, when they divide, they only make more skin cells.

最后，那些只能复制它们自己的细胞就是单独型干细胞，像皮肤细胞，当它分裂的时候，它只能制造更多的皮肤细胞。

Proliferation experiment: transformed endometrial glandular epithelium cells doubing time about 52.8 hour, after exponential phase of growth,cells arrest accrementition, activity depress, the ability of ingest MTT drop out.

细胞增殖实验：转化后细胞倍增时间约为52.8小时，对数生长期后细胞停止分裂增生，活性降低，摄取MTT的能力下降。

Efaroxan 10 μmol· L^-1 inhibit proliferation effect of agmatine on neural stem cell.

结果从新生大鼠海马分离得到的细胞可以持续分裂增殖形成细胞克隆；胍丁胺1、10μmol·L^-1可以显著促进神经前体细胞的增殖，并且这种促增殖作用可以被依法克生所抑制。

The two cells that produced by the amicronucleate cell were still without micronucleus.

在整个接合过程中，无小核细胞的大核始终没有发生可观察到的形态学变化，它最终分裂成的二个子细胞仍为无小核细胞。

Results Hela/MMC cells possessed the ability of 5.02 fold resistance to MMC and 2.03 fold cross-resistance to Capsulation and maintain the sensitivity to vincristine, adriamycin and 5-flurouracil (5-Fu).

结果 Hela/MMC细胞对MMC有5.02倍耐药，对DDP有2.03倍交叉耐药，对VCR、ADM和5-Fu保持敏感；耐药细胞核分裂指数增加；耐药细胞内丝裂霉素蓄积量比亲代细胞低32.64%(P.01)。

Centrins play a fundamental role in centrosome duplication and contraction of centrin-based fiber systems in eukaryotic cells.

中心蛋白是真核细胞中一种重要的蛋白质，与细胞中纤维的收缩、细胞的分裂等密切相关。

Epidermal growth factor has an important positively influence on cytotrophoblast invasion, while Transform growth factor-β〓 has a negative influence.

如表皮生长因子为一种强的促有丝分裂因子，对滋养细胞侵蚀有促进作用；而转化生长因子-β为免疫细胞抑制因子，对滋养细胞侵蚀有抑制作用。

The place and time of cell proliferation are just in accordance with those of the appearances of stem cells and stem-cell blastemas, which means that cells in those areas mentioned above dedifferentiate forming stem cells which proliferate too.

这些分裂细胞在位置和时间上与干细胞及干细胞原基的出现一一对应，表明上述几处发生了细胞的脱分化，形成了干细胞，进行着细胞增殖。

It shows that As2O3 has marked cytogenetic toxic effect on the root tip cells of Vicia Faba,and effect of accumulating the metaphases in mitosis.

结论是As2O3对蚕豆根尖细胞具有明显的细胞遗传学毒性效应，并具有积累有丝分裂中期细胞的效应。

The inhibition of NCS to eukaryote growth may be due to prolong the cell division and prevent protein synthesis. The inhibition of NCS to Cetruisine fermentum growth was not seem to kill cells and NCS inhibition could be resumed.

NCS抑制酵母细胞生长的可能机理是：一方面使多数细胞处于G1期，而影响了细胞的分裂，另一方面是对蛋白质合成的抑制。

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。
