Releasates from activated platelets include growth factors such as platelet-derived growth factor, vascular endothelial growth factor, and transforming growth factor beta, and may support tumor growth and may promote the establishment of metastatic tumor sites (Kepner and Lipton, 1981; Assoian et al., 1983; Mohle et al., 1997; Nierodzik and Karpatkin, 2006). This evidence concerns the gene VEGFA and neoplasm.
