derives from patient having disease immortal human epithelium-derived cell line cell OV7 cell EFO: EFO_0006459 The OV7 cell line was established from solid ovarian tumour tissue taken from a 78-year-old female patient. The tumour was characterised as stage III, mixed tumour type and poorly differentiated. http://www.ebi.ac.uk/ols/ontologies/efo/terms?short_form=EFO_0006459 Immunocytochemical staining of the cells was reported to show strong staining for cytokeratin (CK), no staining for carcinoembryonic antigen (CEA) and strong staining for human milk fat globulin (HMFG-2). Detection of mRNA expression of vascular endothelial growth factor (VEGF) and its receptors flt and KDR has been reported. The patient had received treatment with chlorambucil.
