In vitro collagen-induced platelet microparticle generation and effects of antiplatelet agents. (A) PMP generation induced by collagen type I at high (10 μg/mL) and low (1.5 μg/mL) concentration in freshly isolated PRP under low shear stress conditions; (B,C) Effects of ASA at high (100 μmol/L) and low (10 μmol/L) concentration on platelet microvesiculation triggered by collagen type I (10 and 1.5 μg/mL). (D,E,F) Effects of SQ 29,548 (20 μmol/L), apyrase (10 U/mL) and PSB-0739 (500 nmol/L) on in vitro PMPs shedding induced by collagen type I (10 and 1.5 μg/mL). ∗P < 0.05; ∗∗P < 0.01; ∗∗∗P < 0.001.
