Figure 5: CTMP promotes HNSCC invasion.

To elucidate the effect of CTMP on cell invasive phenotype, a Transwell chamber assay using Matrigel was performed. Each cell line was seeded onto a filter (pore size, 8 μm) coated with Matrigel in the upper chamber. After 48 h of transfection with CTMP-specific cDNA (A,C) or siRNA (B,D), the cells attached to the lower chamber were stained with crystal violet. Each figure is representative of three independent experiments. Scr, scrambled; **P < 0.01; ***P < 0.001. Scale bar = 50 μm.
