Effects of Col003 on P-selectin expression and ROS generation induced by collagen in rat platelets. (Ai) Representative scatterplots of P-selectin expression in IgG (negative control), vehicle, and Col003-treated platelets (Aii) The percentage of P-selectin–positive platelets were quantified. The %P-selectin–positive platelets in three different groups were 25.73 ± 0.35% (IgG), 58.43 ± 0.50% (Vehicle), 42.83 ± 1.49% (Col003), respectively. (Bi) Flow cytometry of DCHF-DA–loaded platelets in washed platelets treated with either vehicle or Col003 showing collagen-induced ROS generation. (Bii) The percentage of DCF-positive platelets was quantified. The %DCF-positive events in different three groups were 19.30 ± 1.31% (Resting), 51.08 ± 1.74% (Vehicle), 25.60 ± 3.85% (Col003 50uM), respectively. Statistical analysis was performed with unpaired two-tailed Student’s t-test (**p < 0.01 and ***p < 0.001).
