“…Most human ovarian cancer cell lines described were derived from ascites or pleural e usion (Alama et al, 1996;Bast et al, 1981;Buller et al, 1995;DiSaia et al, 1975;Fogh and Trempe, 1975;Golombick and Bezwoda, 1991;Golombick et al, 1990;Grunt et al, 1993;Hamilton et al, 1983;Hirte et al, 1994;Langdon et al, 1988;Provencher et al, 1993;Sinna et al, 1979;Wong et al, 1990;Yamada et al, 1991), with only a few cell lines derived from primary ovarian solid tumors (Crickard et al, 1989;Langdon et al, 1988;Woods et al, 1979) or metastases (Buick et al, 1985). In addition, most cell lines originate from tumor material obtained following adjuvant therapy such as chemotherapy or radiation therapy, which could introduce confounding genetic events.…”
