Advances in oncolytic adenovirus-loaded mesenchymal stem cells for treating tumors / 中国肿瘤临床

ABSTRACT

Oncolytic adenoviruses have been used in cancer gene therapy because of their ability to selectively transfect and repli-cate in tumor cells. However, systemically administering oncolytic adenoviruses is often inefficient because the host's immunity also at-tacks the viruses. Delivering oncolytic adenoviruses by loading them into mesenchymal stem cells effectively solves this problem. Mes-enchymal stem cells have been described to possess a tumor-homing ability, as well as the capacity to deliver oncolytic adenoviruses. This review discusses the current challenges faced by oncolytic adenovirus delivery via mesenchymal stem cells.
