细胞分裂

The actual hair shaft, as well as an inner and outer root sheath, develops from the mitotically active undifferentiated cells of the matrix portion of the hair bulb.

实际的毛干和内、外根鞘，是毛球的母质部分的未分化细胞活跃分裂的结果。

Methods:Immunohistochemical technique was used to detect the p21 WAF1/CIP1and P53 protein expressions in:20 usual leiomyoma,70 borderline leiomyoma:including 40 cellular leiomyoma,13 bizarre leiomyoma,4 mitotically active leiomyoma,10 atypical leiomyoma, 3 smooth muscle tumors of uncertain malignant potential and 18 leiomyosarcoma...

应用免疫组织化学法检测 2 0例普通型子宫平滑肌瘤，18例子宫平滑肌肉瘤及 70例交界性子宫平滑肌瘤：包括 4 0例富于细胞型子宫平滑肌瘤、13例奇异型子宫平滑肌瘤、4例核分裂活跃型子宫平滑肌瘤、10例不典型子宫平滑肌瘤及 3例恶性潜能未定型子宫平滑肌瘤的p2 1WAF1/CIP1和P5 3蛋白的表达。

However, compared with their parents, these plants showed some degeneration. Aside from pure diploid plants, mixoploid plants also were obtained by inducing of DMSO. Furthermore, there was much cytology behavior variation of mitosis between pure diploid and mixoploid plants.

DMSO诱导玉米孤雌生殖除获得纯合二倍体植株外，还获得了部分的混倍体，细胞染色体有丝分裂细胞学行为也相对有较大的变异。

Myoblastic cells from patients with PM had a weaker ability of developing into the myotubules, thus they were unable to perform effective regeneration, which resulted in a progressive necrosis. The exogenous bFGF could promote the division and proliferation of the muscle cells in vitro . These results shield a light on bFGF's potential role in preventing and treating PM.

PM患者受损腓肠肌在体外有再生能力，但融合成肌管能力极弱，存在再生障碍，不能对变性、坏死的肌纤维形成有效再生，故呈进行性肌纤维耗竭；外源性bFGF可促进PM患者体外培养骨骼肌细胞增殖分裂，并可促进肌管成熟，对进展性肌病应具有防治作用。

The nonstructural protein NS5A of HCV is likely to be involved in the control of cell growth and viability.

最近的研究证明，NS5A蛋白质可能异常调控细胞周期中的有丝分裂阶段，造成染色体不稳定，进而引发肝癌的发生。

Furthermore, mitotic figures are easily seen, and many cells show prominent nucleoli.

而且，核分裂像易见，许多细胞有明显核仁。

At high magnification, the non-Hodgkin's lymphoma cells have prominent clumped chromatin and nucleoli with occasional mitotic figures.

在高倍镜下可见非霍奇金淋巴瘤细胞的细胞质浓缩，偶尔可见病理性核分裂像。

In order to obtain viable tetraploids, which remains a major challenge worldwide, research on spindle organization and chromosome behavior was carried out mainly in zhikong scallop, Chlamys farreri, a typical commercially important species which is being cultured in North China Sea. Immunofluorescent technique and laser scanning confocal microscopy has been developed for observation of both microtubule organization and chromosome segregation. Orcein squash method was also used for chromosome observation. A series of complicated configurations of the meiotic spindle and associated patterns of chromosome segregation, including tripolar and seperated bipolar segregation, were found in developing eggs following the inhibition of the first polar body.

为了攻克可存活四倍体人工培育技术的国际性研究难题，本研究选取了我国北方海区的典型经济贝类栉孔扇贝为主要研究对象，建立了一套免疫荧光染色和激光扫描共聚焦显微技术，结合使用染色体地衣红压片观察技术，对第一极体受抑制的受精卵的减数分裂纺锤体装配、染色体分离动态进行了研究，发现了一系列特殊的纺锤体装配及相应的染色体分离行为，包括三极分离、独立二极分离等分离类型，从亚细胞水平上阐明了四倍体形成的细胞学机理。

Trends in proliferation of GCs treated by FSH, Mel, Pand LH were evident.

FSH、Mel、P_4和LH均具有促进颗粒细胞进入有丝分裂的增殖状态。

HPV infection can arouse the cleavage and proliferation of cholesteatoma epithelium and may play certain role in the occurrence and development of middle ear cholesteatoma. Aggressive, papillomatous growth and koilocytes can be served as the initial proof of HPV infection in cholesteatoma of the middle ear.

HPV感染可能激发中耳胆脂瘤上皮的分裂增殖，在中耳胆脂瘤发生发展中起一定的作用；侵蚀性乳头瘤样生长和空晕细胞改变可以作为中耳胆脂瘤组织中HPV感染的病理学证据。

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
