细胞分裂

Like cell proliferation, differentiation and apoptosis, cellular senescence is a fundamental feature of normal cells.

细胞衰老与细胞分裂、分化和凋亡一样，是细胞的基本生命活动之一。

These results suggest that ASPM gene is involved in cell mitosis, proliferation and differentiation.

这些结果显示ASPM基因与细胞分裂，细胞增殖以及细胞分化有著相关性。

VEGF and its receptor are highly expressed in most malignant tumors, through para/autoendocrine reaction, promoted endothelial cell division, proliferation and induced vascular neogenesis, directly affecting tumor cell and provoking it to grow.

在绝大多数恶性肿瘤中均呈现VEGF及其受体的高表达，以旁／自分泌作用机制，促进内皮细胞分裂、增殖、诱导血管新生，并可直接作用于肿瘤细胞，刺激肿瘤细胞生长。

Based on the Markov chain, the transitive law of the plastid in the splitting process of the cell in biology was first studied and then the pure composition probability of the cell was discussed in detail, including the deletion plastids and the transformation between the different states of the cell.

以随机过程为研究工具研究了生物学中质体随细胞分裂而传递的规律，通过数学建模对含突变质体的杂合细胞的纯合概率和细胞的不同状态之间的转移在生物学意义上进行了详细的讨论。

Basic fibroblast growth factor is a potent mitogen for a variety of mesoderm- and neuroectoderm-derived cells and has been found in aqueous humor, vitreous and other ocular tissues.

碱性成纤维细胞生长因子（basic fibroblast growth factor bFGF）是对广泛来源于中胚层和神经外胚层细胞的有效促细胞分裂因子，已在房水、玻璃体和其它眼组织中发现。

The results show that the hydrophilicity of PLA film is improved by introduction amido: the contact angle decreases from 78° to 56° and the free energy increases from 42.7mJ/m^2 to 51.4mJ/m^2. Compared with the control, osteoblast spread out more filopodia after 3 d incubation on amidation surface, and it entered cell division phase more quickly, which indicated that the surface amidation could promote the cell's adhesion and proliferation on the PLA film.

结果表明，酰胺基的引入改善了PLA膜的表面亲水性，其表面水接触角由78°减少到56°，自由能由42.7mJ/平方公尺增大到51.4mJ/平方公尺；与对照组相比，成骨细胞在改性表面培养3d后有大量的丝状伪足伸出，并且较快地进入了细胞分裂期，表明PLA膜表面的酰胺化能够促进细胞的黏附和增殖。

Observation under Transmission Electron Microscope was carried out and growth curve of E. coli was ploted out. It was indicated that PSPPs might change the permeability of cell membrane, make cell excrescent and inhibit cell division.

透射电镜观察和大肠杆菌生长曲线表明，该色素的抑菌作用可能是通过增强细胞膜的通透性，使细胞异常生长，抑制对数生长期的细胞分裂，使细胞质稀薄、细胞解体。

In contrast, 11/15 primary glioblastomas contained a significant CD133 subpopulation that displayed neurosphere-like, nonadherent growth and asymmetrical cell divisions yielding cells expressing markers characteristic for all three neural lineages.

相反，15个原代胶质母细胞瘤中有11个含有明显的CD133阳性亚群，呈神经球样，非附着性生长和非对称性细胞分裂，后者产生表达所有三种神经细胞系的特征标志物的细胞。15

The results showed that the non-embryonic callus were cultured on the MS medium contained 4.0 mg · L-1 2,4-D and 0.5 mg · L-1 6-BA, embryogenic cells appeared in it. Then the single embryogenic cells formed a proembryo composed of many cells through cell division.

结果表明，非胚性愈伤组织转入到MS + 4.0 mg · L-1 2，4-D + 0.5 mg · L-1 6-BA培养基培养后，愈伤组织中先出现一些胚性细胞；然后单个胚性细胞分裂形成一个由多细胞组成的原胚。

In functional study, overexpression assay was conducted in potato. Interestingly, tuberous swelling along roots was observed in some transgenic potato lines in addition to stem-derived tuber formation. Conclusively, we propose a hypothesis to illustrate the mechanism by which IbMADS1 participates in the initiation of tuberization in sweet potato.

利用解剖切片观察并比较转殖马铃薯与野生型甘薯的根部块状膨大区域，可以发现两者在膨大初期，中柱内含的细胞数皆增多，尤其是木质部细胞出现不正常增生情形，进而扩展中柱区域；因此，我们可以初步推论在甘薯块根发育初期，IbMADS1藉著作用於根部分生组织，尤其是中柱的原始形成层，从而促进细胞分裂，并参与甘薯的初期结薯。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.

实际上 我们已接通卫星可视电话了
