摘要: Adult neovascularization relies on the recruitment of circulating cells, but their angiogenic roles and mechanisms are unclear. We show that endothelial growth factor VEGF is sufficient for organ homing mononuclear myeloid cells required perivascular positioning retention. Recruited bone marrow-derived (RBCCs) summoned by serve a function distinct from progenitor cells. Retention RBCCs in close proximity to vessels mediated SDF1, chemokine induced activated myofibroblasts. enhance situ proliferation via secreting proangiogenic activities locally activities. Precluding strongly attenuated response addition purified enhanced angiogenesis excision wounds. Together, data suggest model VEGF-programmed adult highlighting essential paracrine role recruited SDF1
