Figure 6. Effect of PGF_2α and P-selectin for PMN adhesion to LECs.

The myeloperoxidase activity of PMNs was measured as an indicator of the number of PMNs (Fig. 6). Before the addition of PMNs, LECs were preincubated with or without anti-P-selectin (10 µg/mL) monoclonal antibody for 30 min. PMNs were added onto LECs with or without PGF_2α (10⁻⁶ M) for 30 min (n = 4 in each group). All values are the means ± SEM. Different superscripts indicate significant differences (P<0.05).
