Stemness markers distribution on EMT-ACHN and EMT-786-0 cells. A: Real time RT-PCR evaluation for Oct 4, Nanog and Bmi-1 genes on ACHN and EMT-ACHN cells; B: Real time RT-PCR evaluation for Oct 4, Nanog and Bmi-1 genes on 786-0 and EMT-786-0 cells; C: Western blot for Oct 4, Nanog and Bmi-1 genes on ACHN and EMT-ACHN cells; D: Western blot for Oct 4, Nanog and Bmi-1 genes on 786-0 and EMT-786-0 cells. *P < 0.05 compared to ACHN, #P < 0.05 compared to 786-0.
