The SCC9-S cells that undergo the epithelial to mesenchymal transition (EMT) are associated with highly invasive and metastatic behaviour. (a) The cells invading the filters coated with the extracellular matrix (ECM) gel. The photographs were taken at × 100 magnification. (b) The quantification of the cell invasion in 10 randomly chosen fields. The data were reported as mean±s.d. **P<0.01 compared with that of SCC9 cells transfected with an empty vector (SCC9-N) cells. (c) The quantification of cell adhesion at two time points. The data were reported as mean±s.d. **P<0.01.
