WBC population in thrombus from different vascular beds. RNA was extracted from the whole thrombus from different vascular beds. Gene expression (numerator) is shown relative to 2 housekeeping genes (actin and glyceraldehyde-3-phosphate dehydrogenase) (denominator) and reported as mean ± SEM. Differences between groups by 2-way analysis of variance (n = 4-5). BCELL, B Lymphocyte; Cq, cycle threshold; MAC, macrophage; MPO, myeloperoxidase; NEUT, neutrophil; TCELL, T lymphocyte.
