Illustration of a “double-lock” mechanism mediating EPC homing to ischemic wounds tissues for therapeutic neovascularization and wound repair.
SDF-1α acts both locally and remotely to induce ischemic tissue endothelium and BMD-EPC to express E-selectin/ligands. Dual E-selectin/ligand pairs reciprocally expressed on activated endothelium and BMD-EPC mediate enhanced EPC-EC interactions and selective EPC homing.
