Blood samples were collected by cardiac puncture in 3.8% sodium citrate (10:1) and hematology studies were performed. Graphs show counts of (A) white blood cells (WBC), (B) lymphocytes (LY), (C) neutrophils (PMN), and (D) platelets in clopidogrel-treated or untreated mice. Both sham and CLP samples were analyzed for treated and untreated mice. Values are expressed as 1×103 cells/μL, mean ± S.E.M., (n = 8; *p<0.05 WT sham versus CLP mice; **p<0.01 treated CLP versus untreated CLP).
