(e) bEnd.3 microvascular endothelial cells upon exposure to recombinant murine uPA-PAI-1, the uPA-PAI-1 inhibitor WX-340, or primary neutrophils isolated from the peritoneal cavity of WT mice undergoing 6 h of intra-peritoneal stimulation with uPA-PAI-1 with or without addition of a NE inhibitor as assessed by a MTT assay, quantitative data are shown (mean±SEM for n=3 experiments per group; #p<0.05 vs. neutrophils; *p<0.05 vs. neutrophils + vehicle / #p<0.05 vs. 2 % FCS medium; One-way ANOVA / t-test).
