Adhesion of HL60 to HCMEC is blocked by MoAb BBA2 against E-selectin. At shear stresses <1.0 dyne/cm2, adhesion of HL60 cells to TNF-α–stimulated HCMEC was significantly blocked by preincubation with MoAb BBA2. No adhesion is seen on unstimulated HCMEC. Mean values ±SEM; * P < .05 versus positive control.
