Studies have reported that TAMs promote tumor angiogenesis and blood‐derived cell metastasis by secreting a large amount of proangiogenic factors, such as vascular endothelial growth factor (VEGF).[33] TAMs can also produce immunosuppressive factors, such as IL‐10, TGFβ, and PGE2, etc., which promote the occurrence and development of tumors by inhibiting the antitumor immune response. The gene discussed is VEGFA; the disease is neoplasm.
