Hypoxic macrophages are known to respond to hypoxia by upregulating hypoxia-inducible transcription factors (mainly hypoxia-inducible factors HIF1 and HIF2)38, 39, the activation of which leads to increased transcription of many genes that regulate cell proliferation, metabolism and angiogenesis40.
Hypoxia induces a distinct pro-angiogenic phenotype in human macrophages in vitro42, 43 including the upregulation of VEGF, bFGF, CXCL8, COX2, hepatocyte growth factor (HGF), VEGFR1, tissue factor (F3) and MMP12.
