Adherence of umbilical cord and adult peripheral blood PMN to human coronary artery endothelial cells incubated with methyl arachidonyl fluorophosphonate (MAFP, 5 μM, 10 mins) followed by thrombin (1U/ml, 10 mins) or phorbol 12-myristate 13-acetate (PMA, 100nM, 10 mins). **p<0.01 when compared to control. No statistical difference was detected between umbilical cord and adult peripheral blood under each experimental condition. Data shown are mean + SEM for 6 separate isolations
