Fig 5. Western blot analysis of CD31, VEGF and VEGFR2.

(A) Western blots showing two representative samples per treatment group. (B) At day 21 post implantation expression was quantified and represented as a fold change from SD (N = 6 for SD and N = 5 for KC; *p < 0.05). (C) Expression of genes involved in angiogenesis was analyzed using RT-PCR. Data represented as the fold change difference in expression from SD tumors (N = 3; *p < 0.05; **p < 0.01).
