Sox2-positive cells exhibit more EMT features but do not show altered proliferation <i>in vitro</i>.

<p>(A) Real-time PCR analysis of the mRNA levels of various EMT-related genes in SiHa-EGFP⁺ and SiHa-EGFP⁻ cells. EMT-related gene expression was measured by western blot (B) and immunochemistry (C) in SiHa-EGFP⁺ and SiHa-EGFP⁻ cells. (D) Immunochemistry for Sox2 and EMT-related genes in tumor xenografts. Bars = SE. *, p<0.05.
