Figure 6.
The microvessel densities of tumors were reduced by MIL60. (a) Colon carcinoma (HT-29) sections were stained with an anti-CD31 antibody and the microvessel density was calculated and showed similar inhibitory activity of MIL60 against angiogenesis as Avastin in vivo. Arrow points represent new vessels. (b) The vessel length of each group is shown in a column diagram, which also shows the P values between the indicated groups.
