  • Description: The PEO1 Cell Line is one of nine from the PE ovarian adenocarcinoma panel (derived from 4 patients at varying stages of ovarian cancer, isolated from various malignant sites, and at various treatment stages) which provides a model system for research into the mechanism of oestrogen action on ovarian adenocarcinoma tumour cells, and for the study of efficacy and toxicity of oestrogen protagonists. PEO1 is an adherent cell line derived from a malignant effusion from the peritoneal ascites of a patient with a poorly differentiated serous adenocarcinoma. The patient previously received cisplatin, 5-fluorouracil and chlorambucil treatment. PEO1 is tumourigenic in immunologically-deprived CBA mice. PEO1 exhibits good growth in semi-solid medium (agar). PEO1 is from the same patient as the PEO4 and PEO6 cell lines
  • Biosafety level: 2
  • Additional notes: Please be aware that the originating laboratory of the PEO1 cell line acknowledges that PEO1 is both genetically unstable and derived from a heterogeneous population that was already present in the patient at the time of biopsy. This is evident in the literature (Cooke et al., 2010). Genetic differences within the PEO1 PEO4 and PEO6 cell lines suggest that PEO4 and PEO6 are not direct descendants of PEO1 but have diverged from a common ancestor
