Sos1 depletion alters focal adhesion and F-actin distribution in primary MEFs. Representative confocal microscopy images of individual primary MEFs from the four genotypes (Sos1/2WT, Sos1KO, Sos2KO and Sos1/2DKO) stained with for actin filaments with phalloidin (green), focal adhesions (FA) with anti-Paxillin antibody (red) and for nuclei with DAPI (blue). Arrows show predominant areas of FA localization in Sos1/2WT and Sos2KO MEFs. Scale bar: 25 μm
