Systemic levels of soluble E selectin (sE Selectin), myeloperoxidase (MPO), monocyte chemoattractant protein-1 (MCP-1), and macrophage inflammatory protein-1 delta (MIP-1δ) correlated directly with the number of circulating inflammatory endothelial cells (IEC, A, C, E, G), but inversely with the number of circulating endothelial progenitor cells (EPC, B, D, F, H).
