CXCL1 promotes arteriogenesis through enhanced monocyte recruitment into the peri-collateral space

Aims The mechanisms of monocyte recruitment to arteriogenic collaterals are largely unknown. We investigated the role of chemokine (C-X-C-motif) ligand 1 (CXCL1) and its cognate receptor, chemokine (C-X-C-motif) receptor 2 (CXCR2) in arteriogenesis.
