Figure 1. Fibroblast spreading in PDGF medium on 1.5 mg/ml and 4 mg/ml collagen matrices.

Figure 1

Fibroblasts were cultured 4 hr on 1.5 mg/ml and 4 mg/ml collagen matrices in PDGF medium. At the end of incubations, samples were fixed and stained for actin and vinculin. Judging from appearance of stress fibers and focal adhesions, cells on 4 mg/ml collagen matrices developed high cell-matrix tension state. Scale bar, 50 μm (insert; 20 μm)
