TABLE 2.

Average rolling velocities (μm/s) of wild-type, CD44-knockdown, CEA-knockdown, and CEA/CD44-double knockdown LS174T cells (106/ml) perfused over a surface coated with 0.75 μg/ml E-selectin at the physiological shear stress levels of 1.0 or 2.0 dynes/cm2

Data represent the mean ± S.E.

	Average rolling velocity
	1.0 dyne/cm2	2.0 dynes/cm2
	μm/s
Wild-type LS174T	5.3 ± 0.3	7.2 ± 0.4
CD44-knockdown LS174T	5.1 ± 0.3	6.9 ± 0.5
CEA-knockdown LS174T	5.2 ± 0.4	7.1 ± 0.5
CEA/CD44-knockdown LS174T	5.2 ± 0.4	10 ± 1a,b,c

^aValues are p < 0.05 with respect to wild-type LS174T cells.

^bValues are p < 0.05 with respect to CD44-knockdown LS174T cells.

^cValues are p < 0.05 with respect to CEA-knockdown LS174T cells.
