7、ment in ovary; physiologic processes that are highlydependent upon neovascularization. The growth of established human tumor xenografts (colon, lung, prostate,breast, and ovary) in athymic mice is inhibited dose-dependently by Cediranib, with chronic administration of 1.5 mgper kg per day producing

8、statistically significant inhibition in all models. A histologic analysis of Calu-6 lung tumorstreated with Cediranib reveals a reduction in microvessel density within 52 hours that becomes progressively greaterwith the duration of treatment. These changes are indicative of vascular regression withi

Tumors are collected (6-15 per group) 4 hours afterthe last dose of Cediranib or vehicle, on days 1, 2, 7, 14, and 21. CD31 is then detected in sections using a chromagenend point or fluorescent immunosta
