TABLE 2.

Shear flow-induced directed migration of fln^– cells expressing mCherry-tagged ddFLN or empty vector.

Strain	Velocity (μm/min)	Directness	Forward migration index
fln– + ddFLN	7.4 ± 0.4a	0.51 ± 0.02	0.5 ± 0.1
fln– + vector	6.1 ± 1.2	0.48 ± 0.01	0.1 ± 0.2*

^aValues are mean ± SE of three experiments with 50 cells analyzed and averaged for each experiment. Images were acquired every 10 s for 20 min while cells were continuously exposed to 6 dyn/cm² shear stress. Cells were tracked for the last 18 min for analysis. *P < 0.05 compared to fln^– + ddFLN cells.
