Cells were lysed in SDS sample buffer composed of 1.5% dithiothreitol, 2% SDS, 80 mM Tris-HCl (pH 6.8), 10% glycerol and 0.01% bromophenol blue. The lysates were boiled in the buffer for 5 min and separated by SDS-PAGE. Proteins were transferred to nitrocellulose membranes. The membranes were blocked with bovine serum albumin or milk for 1 h and probed with use of primary antibodies followed by horseradish peroxidase-conjugated secondary antibodies (Fisher Scientific). Proteins were visualized by enhanced chemiluminescence (Fisher Scientific) using the GE Imager 600 System. Antibody used were anti-Plk-1 (Millipore, Cat#05-844, Lot#2477015), anti-c-Abl (Cell Signaling, Cat#2862 S, Lot#13), anti-paxillin (BD Biosciences, Cat#610051, Lot#7208686), anti-GAPDH (glyceraldehyde 3-phosphate dehydrogenase.

Seeded cells were washed with PBS, fixed for 30 min with 4% PFA, washed with PBS 3 times for 5 min, and permeabilized for 5 min with 0.3% Triton. Cells were then blocked for 1 h with 10% BSA and 3% milk diluted in PBS at room temperature (RT). Cells were next immunolabeled for 2 h with a primary anti-paxillin antibody (Merck Millipore, Burlington, MA, USA, dilution of 1:200), then incubated for 1 h at RT with an Alexa Fluor secondary antibody (ThermoFisher, Waltham, MA, USA, 1:500), Alexa Fluor Phalloidin (ThermoFisher, 1 U/mL), and Hoechst (ThermoFisher, 1:1000), all diluted in 1% PBS/BSA solution. Cells were then washed with PBS 3 times for 5 min. Coverslips containing resting cells were mounted with Dako Faramount Aqueous Mounting Medium on SuperFrost Plus microscope slides, and migrating cells were directly visualized in Ibidi chambers using the COSD confocal microscope with a plan-Apochromat 63x/1.4 water-immersion objective. The quantification of FA number and cell surface occupancy was performed as previously described [27 (link),46 (link)]. The number of FAs was then normalized to the total cell surface, while surface occupancy distinguished the cell front, center, and rear. The quantification of actin cytoskeleton cell surface occupancy was performed using the same method. The quantification of FA and F-actin polarization was determined by the proportion of FA or F-actin area at the cell front, center, or rear compared to the total area of FA or F-actin.
