Figure 1

RBC motions under shear flow (orange arrows) near a wall. Top: tank-treading motion of a highly deformable cell. The cell keeps a constant orientation with respect to the flow direction (direction of the orange arrows). The cell membrane rolls like the caterpillar of a tank; schematic representation: projection of the cell in the shear plane, ‘side view’, and example of a time sequence of 16 images of a RBC obtained by videomicroscopy: projection of the tank-treading cell perpendicular to the shear gradient direction, top view. Bottom: non tank-treading motion, here flipping, of a poorly deformable RBC. The cell tumbles in the flow like a coin, its orientation changes with respect to the flow direction; schematic representation: projection of the cell in side view and example of a time sequence of 20 images of a RBC obtained by videomicroscopy: projection of the tumbling cell in top view. Image acquisition frequency: 60 images/sec.
