Figure 5. Immunohistochemistry staining of VEGF-A expression in the pleural tumors.

Figure 5

Positive immunohistochemistry staining of VEGF-A was shown as brown part in each figure. Expression of VEGF-A was accessed by the percentage of positive carcinoma cells and the staining intensity. The positive staining of VEGF-A in NS group (A) and L-ES group (B) indicated high expression of VEGF-A in these groups. Low expression of VEGF-A was shown in Bevacizumab group (C) and H-ES group (D). The expression of VEGF-A was significantly decreased in H-ES group compared with that in NS group or L-ES group, and there is no significant difference between Bevacizumab group and H-ES group (E). Columns: mean value of each group, bars: ±SD. ***P<0.001, **P<0.01, *P<0.05. ns: no significant difference.
