Besides FAPα, CAF-derived SDF-1, also known as CXCL12, has been shown to promote tumor growth, motility, and tumor angiogenesis in multiple cancer types, including ovarian cancer, by interacting with the CXCR4 receptors on cancer cells [78,79,80,81,82]. The gene discussed is CXCL12; the disease is ovarian carcinoma.
