【摘要】 第一部分 不同侵袭转移潜能卵巢癌细胞亚系的筛选 目的:筛选不同侵袭转移潜能的卵巢癌细胞亚系。 方法:将卵巢癌细胞系SKOV—3和3AO分别接种于裸鼠腹腔,建立卵巢癌腹腔转移的裸鼠模型;并将同一部位转移灶体外建系,在裸鼠体内多次传代,得到卵巢癌细胞亚系(SKOV—3F3、3AOF3和3AOF4)。通过观察不同卵巢癌细胞亚系(SKOV—3、SKOV—3F3;3AO、3AOF3和3AOF4)的成瘤率、在裸鼠体内的转移情况(转移范围、瘤结节重量及腹水形成情况),结合细胞生长曲线、细胞体外黏附实验、人工基底膜侵袭实验、细胞体外移动实验等,比较上述卵巢癌细胞亚系的侵袭转移潜能,并对各细胞亚系的染色体进行显示,分析其遗传背景。 结果: 1、SKOV—3细胞系及其亚系 SKOV—3F3体外生长快,体外黏附细胞数、侵袭人工基底膜及穿透基底膜的细胞数显著多于SKOV—3,裸鼠体内成瘤率为6/6,并有血性腹水形成,而SKOV—3的体内成瘤率仅为6/10,并无腹水形成。经上述实验检测证明:SKOV—3F3与其母系SKOV—3相比为高侵袭转移细胞亚系。染色体分析显示SKOV—3及SKOV—3F3具备人类肿瘤染色体特征,均为非整倍体,以亚二倍体居多,染色体的众数(modalnumber)分布范围类似,证明二者具有相同的遗传背景。
【Abstract】 PART ONETHE SCREENING OF OVARIAN CANCER CELL LINES WITH DIFFERENT INVASIVE AND METASTATIC POTENTIALOBJECTIVE: To screen the ovarian cancer cell lines with different invasive and metastatic potential.METHODS: Human ovarian carcinoma SKOV-3 and 3A0 cells were respectively injected intraperitoneally into female nude mice to establish transplantation models of human ovarian carcinoma. The metastatic tumors derived from the same organ were cultured in vitro, then cell lines were established and transplanted intraperitoneally for several times. At last, we got three cell lines(SKOV-3F3, 3AOF3 and 3AOF4) and evaluated their invasive and metastatic potential by growth in vitro, adhesive test in vitro, Matrigel invasion assay, tumor formation rates and the states of metastasis in vivo and so on. At the same time, our research analyzed the karyotypes of those cell lines.RESULTS:
