Abstract:
Stromal cell-derived factor-1 (SDF-1) is a CXC chemokine that binds to its sole counterreceptor, CXCR4. It is well reported that the SDF-1/CXCR4 signaling pathway is of vital importance to human development and to various pathophysiological phenomena, including hematopoiesis, angiogenesis, atherosclerosis, cancer growth, metastasis, and human immunodeficiency virus infection. SDF-1 promotes mobilization of bone marrow-derived endothelial progenitor cells (EPCs) to the circulation in response to vascular injury. Recently, we found that platelets express and release SDF-1 into the microcirculation upon activation and we observed that platelet-derived SDF-1 is functionally involved in recruitment of EPCs to arterial thrombi in vivo. This review discusses the unique functions of this chemokine and the newly discovered impact of platelet-derived SDF-1 into the recruitment of progenitor cells to vascular injury areas, and its subsequent effects in atherosclerosis, vascular repair, and angiogenesis.

Structure and Function of Platelets
Platelets are continually replenished, circulating in the bloodstream for 9-12 days before being removed by phagocytes, primarily in the spleen. A microliter of circulating blood contains between 150,000 and 450,000 platelets, with...

Formation of the Platelet Plug
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...
