Which growth factors are produced by macrophages that promote angiogenesis?

Macrophages drive angiogenesis in healing by releasing growth factors that directly stimulate new blood vessel formation and maturation. The key trio produced by these cells includes VEGF, which is the primary signal that promotes endothelial proliferation and sprouting; PDGF, which recruits mural cells like pericytes and smooth muscle to stabilize the new vessels; and TGF-beta, which supports extracellular matrix formation and remodeling to provide a scaffold and aid vessel maturation. Together, VEGF, PDGF, and TGF-beta from macrophages create the pro-angiogenic environment essential for new vessel growth during tissue repair. Other listed factors are more associated with general inflammation or other cell sources and are not the main macrophage-derived drivers of angiogenesis in wound healing.
