Fig. S4
Fibronectin is not required for homogeneous WM226-4 cell invasion and collagen I deposition is independent of fibronectin. (Related to Figure 5.) (A) Wholemount immunofluorescence labelling of fibronectin in homogeneous xenografts of control (upper panel) and shFN#1 WM266-4 cells (lower panel). Mean ± SEM; unpaired Student’s T-test; N ≥ 15 from 3 independent experiments. (B) Wholemount immunofluorescence labelling of fibronectin and collagen I in homogeneous xenografts of control (top panel) and shFN#1 (bottom panel) WM266-4 cells. Scale bars = 100 μm. (C) Western blot showing fibronectin and collagen I expression in control and shFN#1 WM266-4 cells. (D) Relative invasion quantification of (A). |
