P-selectin edge directs the motion of rolling cells. Rolling HL-60 cells that encountered the edge of a P-selectin pattern making an angle to the fluid flow direction were forced to roll along the edge. The motion of a cell forced to roll along the edge is compared with another cell rolling in the direction of fluid flow, highlighted by circles. The edge succeeded in changing the direction of motion of the rolling cell by 8.6°, resulting in effectively displacing the cell by 0.15 mm from its original position for every 1 mm of length along the direction of flow. Wall shear stress was 1.9 dynes/cm2. Videos are available in Supporting Information.
