PEO1 and PEO4 are part of our validated ovarian adenocarcinoma cell lines derived from patients at varying stages of cancer and treatment. These models can be used to better understand mechanisms of oestrogen action, as well as efficacy and toxicity of oestrogen protagonists in ovarian adenocarcinoma. They have been used to generate rich preclinical data and to optimise drug discovery pipelines, including target validation and drug screening.
PEO1 ovarian cancer cell line

Inventor: Simon Langdon
Institute: Cancer Research UK Edinburgh Centre
- Tissue: Ovary
- Organism: Human
- Cell type: Adherent epithelial
- Applications: Preclinical and in vitro studies, target validation, drug screening
PEO1 is derived from a patient who received treatment for a poorly differentiated serous adenocarcinoma.
PEO4 ovarian cancer cell line

Inventor: Simon Langdon
Institute: Cancer Research UK Edinburgh Centre
- Tissue: Ovary
- Organism: Human
- Cell type: Adherent epithelial
- Applications: Preclinical and in vitro studies, target validation, drug screening
PEO4 was collected from the same patient as the PEO1 line but after clinical resistance developed to chemotherapy.
