A) 30 μM FPP has an additive effect on 10 μM LPA-mediated platelet shape/change. (Student’s t-test: *p=0.017, n=10). Representative shape/change curves from platelets treated with LPA 10 μM and platelets first pre-treated with FPP, 30 μM for 5 min and further treated with LPA 10 μM. B) LTA on platelets aggregation with LPA (10 μM) alone or with platelets pre-incubated with FPP (30 μM) or NAG (30 μM). No statistically significant inhibitory effect was seen on the platelet aggregation between platelets treated with LPA vs. platelets pre-treated with FPP or NAG (ANOVA: n.sp=0.13, n=8). The values from the turbometric LTA PRP tests are presented as mean platelet aggregation (MPA), where a mean value is calculated from the sum of all observations divided with the number of observation, and presented in %.
