Figure 2. Anti-B7-H1 antibody inhibition of tumor growth in vivo. Lewis lung carcinoma (LLC) cells were subcutaneously injected into C57BL/6 mice to form xenograft tumors. Anti-B7-H1 or vehicle control (LLC injected group) was administered intravenously every 5 days thereafter. A, Tumor growth was monitored every 5 days by calculating tumor area, which was compared between the anti-B7-H1 and control groups. **P<0.01, compared with the control group (ANOVA). B, Representative images of xenograft tumors on day 30 after LLC injection in the control and anti-B7-H1 groups.
