细胞分裂

We also confirmed in this paper that it is injected somatic cells but not broken cytoplasm formed multi blastomere through mitosis in the reconstructed embryos.

在本实验中还通过用DNA染料（Hoechst-33342）对核移植体进行染色的方法，对融合后成纤维细胞在核移植体内不同时间的运行及发育模式进行了观察，确认了是成纤维细胞经有丝分裂形成多个卵裂球而不是由于细胞质碎裂形成的两个或多个碎块。

This paper briefly describes the progress in cytoplasm reorganization, dynamics of wall callose, starch granules and organelles in pollen grains, the tapetum development, specific genes, asymmetric division and cell fate determination in developing pollens. Some problems and future research directions are pointed out in this review.

本文针对花粉发育过程中的细胞质改组；胼胝质壁、淀粉粒和细胞器的动态变化；绒毡层的发育；花粉发育特异基因；以及不对称分裂和细胞命运等几个生物学问题的研究进展作了简要综述，最后还提出了一些研究展望。

Result: Rhesus BMSC can be got in mass by density gradient centrifugation.; Rhesus BMSC can adhere to PLGA fiber quickly after plant and its growth , division ,proliferration is good; Some cells arrange like rosary on PLGA fiber surface, some cells still form the catenate or flaky cell bridge joined among PLGA fiber.

结果：采用密度梯度离心的方法可得到大量增殖能力强的猕猴骨髓基质干细胞；接种后的骨髓基质干细胞很快粘附于PLGA纤维上，生长、分裂、增殖良好，在PLGA纤维表面形成串珠样排列，部分细胞还形成连接在PLGA纤维间的链状或片状细胞桥。

Cell cycle plays an important role in cell growth, differentiation and division.

中文摘要细胞周期在细胞的生长、分化及分裂过程中扮演着极其重要的角色。

At the same time,there were not marked difference in the numbers of biastomere and mitotic index of control group and all treatment groups, suggesting that 2 -celt embryos were not only most sensitive to exogenous H2O2 but also rasiest to occur to development block.

但是经H2O2处理之后，度过2-细胞期发育阻滞的胚胎能在以后的发育中发生补偿性生长，其胚细胞数和分裂指数都和体外正常发育的胚胎没有差异。

The events of cell cycle take place in the order of timing and space, which ensures that cell division and chromo...

细胞周期各事件按正常时空顺序发生，才能确保遗传信息忠实传递及细胞正常分裂。

Companion cell An elongated thinwalled cell cut off longitudinally from the same meristematic cell as the SIEVE ELEMENT with which it is closely associated.

伴胞：与筛管分子侧面相邻的一种细胞，和筛管间有密集胞间连丝，它与筛管是由分生组织的同一个母细胞不均等分裂发育而成。

Microscopy revealed apoptotic characteristics,including chromatin condensation and cell nucleus fragmentation, demonstratingthat ardipusilloside I induced apoptosis.

ArdipusillosideⅠ治疗后的瘤细胞在显微镜下显示出明显的凋亡特征，包括染色质浓缩边集，细胞核分裂；这表明ArdipusillosideⅠ诱导了瘤细胞凋亡。

After treated with VCR, they were cut down seriously in PAa cells, and manifestations of mitotic arrest of cell cycle increased unusually in PG cells.

超微结构观察见PAa细胞微管、微丝稀疏，VCR作用后进一步减少；PG细胞微管、微丝减缺，VCR作用后分裂期形态多见。

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。
