Notably, these macrophages exhibit a hypoxia-induced phenotype characterized by the secretion of VEGFA and HBEGF, which cooperatively enhance tumor angiogenesis, alongside an elevated expression of the inflammatory chemokines CXCL2, CXCL3, and CXCL8 that consolidate an immunosuppressive, pro-tumorigenic microenvironment. This evidence concerns the gene CXCL2 and neoplasm.
