EV modification (right) is a direct method to obtain engineered EVs, including passive loading cargo, EV membrane modification, hybridization, and biomimetic EV production. Producing cell modification (left) is the indirect method to get engineered EVs through engineering parent cells by active loading cargo or genetic manipulationBack to article page
