In addition, platelets can also target tumor cells by utilizing special receptors and glycoprotein distributions on the surface of tumor cell membranes such as podoplanin, PSGL-1, disintegrin, and metalloproteinase domain-containing protein 9 (ADAM-9), and fibrinogen/αvβ3, which play an antitumor effect [72]. This evidence concerns the gene ADAM9 and neoplasm.
