Effect of EphA2 antibodies on angiogenesis. (a) Representative CD31 immunostaining of paraffin embedded tumor section (magnification bar = 20 m). (b) Quantitative analysis of CD31 staining in tumors treated with control IgG, IgG25, and IgG28. The average data obtained from the analyses of two tumors selected from each group are reported as the percentage of CD31⁺ area in each entire section. In all panels, asterisks indicate statistically significant differences with respect to the control group (Student's t-test; P<.05).
