We found five different subtypes of cancer-associated fibroblasts, FB0 and FB2-5 in both primary and metastatic sites, based on the expression of IL6, CCL2, S100A4, PDPN, and FGF7. Each CAF sub-cluster supports different roles in the progression and metastasis of ovarian cancer. The gene discussed is CCL2; the disease is ovarian carcinoma.
