Immunofluorescence analysis of SCC9 cells, stable SCC9 cells expressing an empty vector (SCC9-N) and MT1-MMP (SCC9-M). (A) Double immunofluorescence staining of E-cadherin (E-cad: red) and vimentin (Vim: orange). (B) Double immunofluorescence staining of cytokeratin 18 (KRT 18: red) and fibronectin (FN: orange). The nuclei in both image sets were stained with DAPI (blue). Images were taken at ×400 magnification. Bar, 100 μm.
