(C) Immunocompetent mice bearing GL261 tumors. Representative MRI images confirmed tumor implantation in all experimental groups (left). Kaplan-Meier curves revealed decreased survival of mice bearing EGFL7 expressing tumors (right; 34 d (control) vs. 29.5 d (hE7) vs. 31.5 d (mE7); n = 8; log-rank test). (D) Immunodeficient mice bearing U87 tumors. Representative magnetic resonance images confirmed tumor implantation in all experimental groups (left). Kaplan-Meier curves revealed decreased survival of mice bearing EGFL7 expressing tumors (right; 70 d (control) vs. 42.5 d (hE7) vs. 40 d (mE7); n = 8; log-rank test)
