Tool Details
- Tool name: OCM.191
- Tool type: Cell Lines
- Tool sub-type: Primary ex vivo culture

- Cancer type: Ovarian cancer; High-grade serous ovarian cancer (HGSOC)
- Morphology: Epithelial
- Growth properties: Adherent
- Model description: FIGO 3A; Ascites; BRCA1 mutation (c.3268C>T; [p.Gln1090Ter]; BRCA2 mutation (c.4725C>G [p.Asp1575Glu]); TP53 mutation (p.R248Q)
- CRISPR: No
- Application: Ex vivo drug-sensitivity profiling; OCM-derived xenograft generation
- Description: The Taylor lab Ovarian Cancer Models (OCMs) are patient-derived tumour cell cultures, unfettered by contaminating, genetically normal stromal cells and the microenvironment. OCMs display the hallmark characteristics of HGSOC and retain the unique molecular features of the original tumour. OCMs have extensive proliferative potential, enabling high-resolution cell biology and drug-sensitivity profiling on tumour cells ‘close to the patient’, i.e. without extensive culture and genetic drift. OCMs are clinically annotated, and have been extensively characterised with associated data sets being publicly available (including multi-omics data e.g. exome and RNA sequencing, and single-cell karyotyping). OCMs can also be used to generate PDX, thus enabling in vivo studies of novel therapies. Collectively, this living biobank represents comprehensive platform for basic research and drug development projects (see PMID: 37592171 for a review)
- Research area: Cancer
- Production details: To establish cultures, red blood cells were lysed, the remaining cellular fraction harvested by centrifugation, disaggregated if necessary then plated in OCMI media. Serial passaging and selective detachment eliminated white blood cells and yielded separate tumour and stromal fractions.

- Temperature: 37C
- Atmosphere: 5% CO2 & 5% O2
- Storage medium: Bambanker freezing solution
- Storage conditions: Liquid nitrogen (1/2 T75 ISO)
