Analysis of tumor microvasculature components and gene expression.

<p>(A) CD31 immunostaining of tissue harvested at 21 days post-implantation. Representative images are shown. (B) Quantification of CD31 staining was performed on 2 independent tumors from each group. Data calculated as the average pixel density in 5 random, 200x fields within the same tumor and represented as a fold change from SD (**p < 0.01).
