OCT4B promotes cervical cancer angiogenesis and EMT.

<p>(A). Tumor xenografts were stained with anti-CD34 antibody. (B). The number of blood vessels was counted. Each column represented the mean ± SD. **, <i>P</i><0.01. (C). Western blot analysis of angiogenesis-associated proteins VEGF, HIF-1α and IL-6, and MMP2 and MMP9. (D) Western blot analysis of EMT-associated proteins E-cadherin, N-cadherin, Twist, Slug and Snail. β-actin was used as loading control. (E) Cytoplasmic OCT4 expression with mesenchymal features in cervical cancer. Three representative samples were shown.
