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.
