CXCL9 and neoplasm: To assess if intratumor delivery of AAV6-CXCL9 is vital for therapeutic efficacy we compared overall survival in GL261 tumor bearing mice where AAV6-CXCL9 (1e10 VGS) was intratumorally (IT) injected, or injected into the contralateral (CL) hemisphere at coordinates symmetrical to intratumor delivery.
