细胞分裂

The aim was to understand the mitotic chromosome aberrations in root tip cell of industrial polluted Stellaria media and micronucleus.

［目的］了解工业污染区繁缕根尖细胞有丝分裂期染色体的畸变和微核。

The reprogarmming of embryonic genome is likely the molecular foundation of the transition of highly differentiated oocytes into totipotential embryonic blastomeres.

基因表达的&再程序化&可能是高度分化的卵母细胞转变成胚胎中具发育全能性分裂球的分子基础。

Hence the receptor- mediated gene transfer is of greater potential for normal undivisible hepatocytes.

因此受体介导的基因转移对于在正常情况下不分裂的肝细胞具有更大的应用潜力。

Results The time of villiform cell culture was obviously related to the kinds of digestive enzyme, but not to the number of karyotypes. The villiform cells of 68 specimens (93.15%) were cultured successfully and 30 abnormal karyotypes were tested.

结果 经不同消化酶处理后，绒毛细胞培养时间具有显著相关性，但与核分裂相的数目无相关性。73例中，68例培养成功，成功率93.15%，检出异常核型30例。

These results indicate that TGA treatment can accelerate GVBD in Xenopus oocytes, and GVBD of mouse oocytes at low dose.

在小鼠中卵母细胞中，低剂量的TGA也可加速第1次减数分裂的启动。

So, HGF is also named as mitogenic factor、scattering factor、morphogen.

因此，HGF又称促有丝分裂因子、离散因子、细胞形态发生素或促迁移因子。

Explants after the cells start to split and divide a series of changes in the structure of the formation of a callus disorder.

外植体的细胞经过启动、分裂和分化等一系列变化，形成了无序结构的愈伤组织。

It inhibits the growth of malignant cells and suppresses the immune system.

它阻止癌细胞的分裂并抑制免疫细胞。

In fact, BDNF potentiates intracellular Ca~(2+) release presynaptically and BDNF-induced TrkB activation also results in phosphorylation of synapsin I via mitoen activated protein kinase, which increases the number of synaptic vesicles available for release.

事实上，BDNF能促进突触前细胞内Ca~(2+)的释放，TrkB的激活也能通过有丝分裂活化蛋白激酶，引起突触素I的磷酸化，进而增加可释放的突触囊泡的数量。

This provided a new technical support to studying regulation, chromosome structure and chromosome translocation identification and accurate measurement and localization of translocated chromosomes.

这为研究细胞有丝分裂的调控、染色体形态结构、易位染色体检测和易位染色体片段的精确测量与定位等提供了新的技术支撑。

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
