N-cadherin knock-down decreases invasiveness of esophageal squamous cell carcinoma in vitro

Figure 2 EGFP expression in PT67 cells and EC9706 cells after pMSCVneo/N-cadherin transfection. A: Selected by 1000 mg/L G418 for 15 d and 300 mg/L G418 for 15 d, the PT-67 cells transfected with pMSCVneo/N-cadherin plasmid expressed EGFP stably. The figure was taken under fluorescence microscope (× 400, at 488 nm); B: Selected by 600 mg/L G418 for 14 d and 300 mg/L G418 for 10 d, the EC9706 cells infected with pMSCVneo/N-cadherin viral supernatant expressed EGFP stably. The figure was taken under fluorescence microscope (× 400, at 488 nm).
