Figure 3.

Effects of aspirin consumption on plasma level of platelet-derived exosomes and their cargo levels. Each column and error bar depicts the mean ± sem for results with platelets from 6 healthy subjects. Values for GPVI, CXCL4, CXCL7, and HMGB1 were normalized for CD81 levels in the same samples. Statistical symbols over the open columns (after aspirin) show significance of differences between levels before and after aspirin consumption determined by a 2-sample t test. *P < 0.01; **P < 0.001.
