P-selectin more than VCAM-1 mediates eosinophil adherence.

Endothelial cells were preincubated with mAbs against either P-selectin or VCAM-1 for 15 minutes before interaction with peripheral blood eosinophils in a parallel flow chamber assay. Total accumulation per high-power field (× 40) after a 2-minute interaction was calculated. **P < .01; n = 5-8.
