Inhibitory effect of Y172F or the ΔN mutant of
Vav2 on HGF/SF-induced cell scattering of MDCK cells. Wild-type MDCK
cells were microinjected with pCIneo-myc-Vav2-Y172F
(Y172F) (Aa–Ad) or pCIneo-myc-Vav2-ΔN-terminal region
(ΔN) (Ba–Bd). At 24 h after microinjection, the cells were
stimulated with no HGF/SF (Aa, Ac, Ba, and Bc) or 10 ng/ml HGF/SF (Ab,
Ad, Bb, and Bd). At 18 h after HGF/SF stimulation, the cells were
double stained with rhodamine-conjugated phalloidin (Actin; Aa, Ab,
Ba, and Bb) or the anti-Myc mAb (Ac, Ad, Bc, and Bd) and analyzed by
confocal microscopy. Confocal images are shown at the basal level. The
results shown are representative of three independent experiments.
