Fig. 2. Cbl-mediated regulation of PDGF-induced actin dorsal ruffle assembly. (A)
Serum-starved wild-type (panels 1 and 3), c-Cbl (panel 5), 480-Cbl (panels 2
and 4) and G306E 480-Cbl- (panel 6) expressing NIH 3T3 cells were either left
untreated (panels 1 and 2) or treated with PDGF for 5 minutes (panels 3-6).
Microfilaments were visualized by confocal fluorescence microscopy (the scale
bar represents 100 µm), and (B) the percentage of cells that form actin
dorsal ruffles at 0, 5 and 15 minutes of PDGF treatment was quantified (see
Materials and Methods).
