Fig. 3. Fluorescence photomicrographs of TRITC-phalloidin–stained NIH3T3 fibroblasts. / (A-B) EGFP alone, (C-D) Rac2D57N, (E) Rac2D57NΔCT, or (F) Rac2D57NΔM. Panels A, C, E, and F were treated with PDGF; panels B and D, no treatment. Arrowheads point to membrane ruffles. Magnification × 400. Inserts show the membrane ruffles at higher magnification (×800).
