查询词典 athymic

A strain of breast tumor cell line ZHL2006 was established and biologically identified. The ZHL2006 cells grew fast in vitro and the population doubling time was 43.6h. Electronmicroscopical observation showed that there were microvilli on the surface of the cells, nucleus irregularity, karyoplasmic ratio increased, nucleolus distinctness, et al.. Chromosome number and structure were abnormal. Immunohistochemistry showed that PCK were expressed. The ZHL2006 cell line could form onto clone in soft agar and had oncogenicity in athymic mice.

ZHL2006细胞在体外生长迅速，群体倍增时间为43.6h；倒置相差显微镜及Giemsa染色镜下观察细胞为多边形及梭形；透射电镜观察可见细胞表面有微绒毛，核高度不规则，核浆比例增大，核仁明显等；染色体数目和结构异常；广谱细胞角蛋白染色阳性，说明其自上皮而非来自基质；同时ZHL2006细胞系在软琼脂中可形成克隆，具裸鼠致瘤性。

Methods Human nasoseptal chondrocytes were seeded onto a nonwoven mesh of polyglycolic acid to form a cell-PGA construct. The construction was then configured in sheet and tube shapes, and implanted subcutaneously into the dorsa of 11 athymic mice. The specimens were harvested 4,6,8 weeks after implantation and subjected to gross morphologic and histologic analysis.

Methods Experimental group were lavaged with MMC for 5 d and 10 mg/kg BW per day after the conduction of the athymic rat model of neuroglioma, control group was given with sodium chloride at the same dose.

制备裸鼠皮下U251胶质瘤模型，随机分为对照组和实验组，实验组裸鼠注射U251脑胶质瘤细胞1 w后，每天灌胃给予10 mg/kg体重MMC，连续5 d，对照组给予相同体积的生理盐水。

Chondrocytes isolated from the same calf suspended in 30% pluronic were then"painted"onto the articular surface of the scaffold and implanted into subcutaneous pockets on the dorsa of athymic mice.

Methods genomic dna was extracted from different stages of malignant transformation and tumorigenicity in inoculated athymic mouse 16hbe cells induced by cadmium chloride and methylating status of genome p16 gene promoter was observed with methylation-specific pcr and then compared with the controls.

从各组cdcl2恶性转化不同阶段及接种裸鼠成瘤的16hbe细胞中提取全基因组dna，采取甲基化特异性pcr法(methylation-specific pcr，msp)检测该基因组p16基因启动子区的甲基化状况，与非转化的16hbe对照细胞进行比较，并用去甲基化因子5-azac (5-aza-2'deoxycytidine)处理有异常甲基化的细胞。
