Ki-67 expression histoscores were significantly different (ANOVA) according to different Oct-4 status in all cases, and in subsets of MVD-negative, MVD-positive, VEGF-negative, and VEGF-positive cases (A). All cases were divided into positive (above the median histoscore) and negative (below the median histoscore) groups. The association of Oct-4 staining with Ki-67 expression was positive in all cases (B), and in subsets of MVD-negative (C), MVD-positive (D), VEGF-negative (E), and VEGF-positive (F) cases. Statistical differences were calculated using Pearson and Spearman correlation analysis.
