Fig 1: Concentration of invasion related factors in cultured medium. (A) Concentration of SDF-1a in cultured medium. (B) Concentration of E-cadherin in cultured medium. (C) Concentration of CXCL9 in cultured medium. (D) Concentration of CXCL10 in cultured medium. (E) Concentration of MMP-2 in cultured medium. (F) Concentration of MMP-9 in cultured medium. Each experiment was repeated for 3 times independently. Data was presented as mean ± SD. P < .05 was set as a statistic difference. *P < .05 compared with normal control group, #P < .05 compared with cetuximab treatment group.
