Exosome as Drug Carriers: After years of hard working in exploring application of exosomes, Creative Biolabs has got all the necessary experience and technologies of exosome engineering. The most usually used approaches are loading naïve exosomes isolated from parental cells ex vitro, loading parental cells with a drug, and transfecting/infecting parental cells with DNA encoding therapeutically active compounds. We will respectively give a brief introduction to each of them.
