Figure 1. Clinical significance of CCL5 and VEGF-C expression in specimens of chondrosarcoma patients.
A. Immunohistochemistry of VEGF-C expression in human normal cartilage and chondrosarcoma tissues. B&C. The quantitative data and correlation between CCL5 and VEGF-C as well as tumor stage. The representative specimens were shown, and the staining intensity was ranked into five groups (1-5) according to the histologic scoring. The correlation analyses were performed by Spearman rank correlation test (R2 > 0.5).
