Fig. 4From: Encapsulation and assessment of therapeutic cargo in engineered exosomes: a systematic reviewCellular experiments and animal models for testing engineered exosomes. In vitro cell studies assess exosome-mediated drug delivery by quantifying drug abundance within cells, measuring changes in cell viability or functionality after exosome treatment. In vivo animal studies establish disease models in rodents or other organisms to test exosome biodistribution and therapeutic efficacyBack to article page
