 Krüppel‐like factor 4 (KLF4) overexpression increased the migration/invasion abilities of SAS. (a) Western blot analysis of KLF4 in five head and neck squamous cell carcinoma (HNSCC) cell lines. (b) Western blot of KLF4 expression in SAS‐K versus SAS‐C clones. (c) Growth curves indicated no growth inhibition in SAS‐K clones. (d) Representative pictures of cells that migrated/invaded through the transwell membrane. (e) The number of cells migrated across the membrane per field. (f) The number of cells invaded through Matrigel per field. The average and standard deviations were shown for three independent experiments. **P < 0.001. NC, normal epithelium.
