Proposed mechanisms. The proposed rescue model of bone marrow cells (BMC) transplantation on enhancing angiogenesis in matrix metalloproteinase- (MMP-) 9 deficient mice with critical limb ischemia. EPC = endothelial progenitor cells; SDF-1α = stromal cell-derived factor-1α; ECM = extracellular matrix.
