Figure 2: VEGF-A expression in Cervical Neoplasia. CIN 3: Cervical intraepithelial neoplasia grade 3; CA: Invasive carcinoma, G1 to G3: Group 1 to Group 3, Min: minimum, Max: maximum, Q1: 1º percentile (25%), Q3: 3º percentile (75%). In CIN 3, VEGF-A expression was higher in tumor cells than in stromal cells. In a comparison between invasive carcinoma and CIN 3, VEGF-A expression showed no change in tumor cells, but increased significantly in stromal cells.
