Natural Killer Cell‐Derived Extracellular Vesicle Preparations Demonstrate Potent Antitumor Activity Against Human Glioblastoma In Vitro and In Vivo
ABSTRACT Extracellular vesicles (EVs) derived from activated natural killer (NK) cells represent a promising cell‐free immunotherapy for cancer. However, the use of primary expanded human NK cell‐derived EVs (NK‐EVs) for intractable brain tumours is underexplored. Here, we evaluated common EV isolation methods includin...
