Fig. 3. Colocalization of internalized fibronectin with {alpha}5 integrins. Smooth muscle cells were incubated with 10 µg/ml TR-fibronectin and 50 µM chloroquine for 8 hours. Cells were stained using an anti-{alpha}5 integrin antibody (AB1928). (A) TR-fibronectin; (B) {alpha}5 integrin; (C) overlay image. These images are optical sections collected from a confocal microscope. Scale bar: 10 µm.
