Platelet ContentsContents include insulin-like growth factor 1, platelet-derived growth factors, TGFβ, platelet factor 4 (which is a heparin-binding chemokine) and other clotting proteins (such as thrombospondin, fibronectin, factor V,[3] and von Willebrand factor).[4] The alpha granules express the adhesion molecule P-selectin[5] and CD63.[6] These are transferred to the membrane after synthesis. The other type of granules within platelets are called dense granules. Clinical significanceA deficiency of alpha granules is known as gray platelet syndrome. See also
