IQGAP1 knockout reduces extravasation of MA2 cells in vivo. (A) Representative images of parental, IQGAP1 knockout or rescued cells (ZsGreen), vasculature (CD31), and nuclei (DAPI) 20 hours after tail-vein injection. Extravasated cells (arrows) and cells still in vasculature (arrowheads) are indicated. Scale bar, 10 µm. (B) Fraction of observed cells that had extravasated. n = 5 mice per group. ns, P > 0.05; ****P ≤ 0.0001; one-way ANOVA with Tukey’s multiple comparisons test.
