Exosomes May Improve Delivery of Anticancer Drugs to Tumors, New Study Suggests

A new study, published on April 20, 2022 as an open-access article in Cancer Medicine, indicates that exosomes, small membrane-bounded vesicles that transport molecules from one cell to another, can be effective vehicles for delivering cancer treatments to tumors. In the study, researchers used exosomes produced by cells called adipose-derived mesenchymal stem cells (ADSCs) to deliver an RNA-based anti-cancer treatment (miR-138-5p) to bladder cancer tumors in mice. “The present results reveal that ADSC-derived exosomes are an effective delivery vehicle for small molecule drugs in vivo, and exosome-delivered miR-138-5p is a promising therapeutic agent for bladder cancer treatment,” the authors wrote.
