In the prostate cancer mouse model, intratumor-injected EVs were more bound to tumor tissue, and TNF-related apoptosis-inducing ligand (TRAIL+) EVs in cholesterol liposomes resulted in a significant reduction in tumor growth in mice (58%), which depended on the intratumoral EVs administration [98, 99]. The gene discussed is TNFSF10; the disease is prostate cancer.
