Stromal compartment profiles from matched clear cell, endometrioid, and high-grade serous ovarian cancers resolve into four shared groups (S1–S4), with S4 desmoplastic/myofibroblast-rich.
- Why it matters: Bulk profiling mixes epithelial and stromal signals, obscuring tumor–stroma crosstalk and limiting how molecular subtype origins are interpreted across epithelial ovarian cancer histotypes.
- What they did: The study performed compartment-resolved transcriptomic and epigenomic profiling on matched carcinoma and stroma from CCOC, ENOC, and HGSC, then compared stromal versus carcinoma segregation patterns.
- The result: S4 is enriched in omental tumors and corresponds to the HGSC C1/Mesenchymal signature, largely reflecting tumor-extrinsic programs and appearing beyond HGSC.
