Several typical methods of EV loading nucleic acid. (A) Loading of small nucleic acid drugs: ASO, using fusion protein method to load miRNA, co-encapsulate siRNA, and chemotherapeutic drugs.

(B) Loading of mRNA: EV-derived cells were pre-transfected to express mRNA plasmid. (C) Loading of CRISPR/Cas9: EVs loaded with sgRNA were fused with liposomes loaded with Cas9-expressing vectors to form hybrid EVs. Adapted with permission from ref. [65].
