The authors have previously reported that dipyridamole decreased platelet-derived growth factor levels in human serum by lowering the release of this factor during blood clotting. In the present study, we have shown that this effect is specific to dipyridamole, and does not occur with other antiplatelet drugs such as aspirin, trapidil or ticlopidine. In addition, dipyridamole has been shown to decrease the PDGF level selectively, but not the levels of other factors from alpha granules in platelets (beta-thromboglobulin and platelet factor 4). These data indicate that dipyridamole may be an effective drug for the prevention of PDGF-related disorders.

UI MeSH Term Description Entries
D008934 Mitogens Substances that stimulate mitosis and lymphocyte transformation. They include not only substances associated with LECTINS, but also substances from streptococci (associated with streptolysin S) and from strains of alpha-toxin-producing staphylococci. (Stedman, 25th ed) Mitogen,Phytomitogen,Phytomitogens
D010978 Platelet Factor 4 A CXC chemokine that is found in the alpha granules of PLATELETS. The protein has a molecular size of 7800 kDa and can occur as a monomer, a dimer or a tetramer depending upon its concentration in solution. Platelet factor 4 has a high affinity for HEPARIN and is often found complexed with GLYCOPROTEINS such as PROTEIN C. Antiheparin Factor,CXCL4 Chemokine,Chemokine CXCL4,Heparin Neutralizing Protein,PF4 (Platelet Factor 4),gamma-Thromboglobulin,CXCL4, Chemokine,Chemokine, CXCL4,gamma Thromboglobulin
D010982 Platelet-Derived Growth Factor Mitogenic peptide growth hormone carried in the alpha-granules of platelets. It is released when platelets adhere to traumatized tissues. Connective tissue cells near the traumatized region respond by initiating the process of replication. Platelet Derived Growth Factor,Factor, Platelet-Derived Growth,Growth Factor, Platelet-Derived
D001792 Blood Platelets Non-nucleated disk-shaped cells formed in the megakaryocyte and found in the blood of all mammals. They are mainly involved in blood coagulation. Platelets,Thrombocytes,Blood Platelet,Platelet,Platelet, Blood,Platelets, Blood,Thrombocyte
D002478 Cells, Cultured Cells propagated in vitro in special media conducive to their growth. Cultured cells are used to study developmental, morphologic, metabolic, physiologic, and genetic processes, among others. Cultured Cells,Cell, Cultured,Cultured Cell
D004176 Dipyridamole A phosphodiesterase inhibitor that blocks uptake and metabolism of adenosine by erythrocytes and vascular endothelial cells. Dipyridamole also potentiates the antiaggregating action of prostacyclin.

D001620 beta-Thromboglobulin A platelet-specific protein which is released when platelets aggregate. Elevated plasma levels have been reported after deep venous thrombosis, pre-eclampsia, myocardial infarction with mural thrombosis, and myeloproliferative disorders. Measurement of beta-thromboglobulin in biological fluids by radioimmunoassay is used for the diagnosis and assessment of progress of thromboembolic disorders. beta-2 Thromboglobulin,Thromboglobulin, beta-2,beta 2 Thromboglobulin,beta Thromboglobulin
