Characterization of human ovarian and endometrial carcinoma cell lines established on extracellular matrix.
Six cell lines were established from four patients with advanced carcinoma of the ovary and from one patient with carcinoma of the endometrium. These lines were established from fresh tumor material maintained initially on culture dishes coated with an extracellular matrix (ECM) produced by bovine corneal endothelial cells. Two of the six lines continue to require ECM as a substrate for optimal growth while the remaining four lines will proliferate on ECM or plastic substrate. Four cell lines transplanted into athymic nude mice were tumorigenic and maintained histologic and karyotypic similarities between the patient's original tumor, the cell line, and the transplantable tumor. Furthermore, in vitro degradation of ECM was grossly apparent by those cell lines which formed nude mice xenografts. Tumor cells were characterized by cytology, transmission electron microscopy, karyology, substrate requirements, steroid binding protein analysis, and morphological appearance in culture.
