Comparison of dorsal SF elongation in control and INF2 KD MEF. Individual dorsal SF in mock transfected MEF (Con, Left) or MEF transfected with siRNA targeting INF2 (KD, Right) cultured on fibronectin-coated coverslips expressing mApple-Actin were photobleached and imaged by spinning disk confocal microscopy. Time indicates minutes:seconds. (Scale bar, 10 µm.)
