Figure 4. The D104N polymorphism in endostatin does not significantly affect angiogenesis in patients with osteosarcoma.
(a) Microvessels were detected using CD31 immunofluorescence in primary tumor samples from OS patients. (b) Microvessels were detected in primary tumors from the LM8 xenograft model. Each bar represents the mean ± SD. Wild, wild type endostatin; p.104DN, heterozygous D104N polymorphism; p.104NN, homozygous of D104N polymorphism.
