Abstract

Exosomes are small nanoparticles secreted by almost all cells and have a well-known role in intercellular communication. They are found in different body fluids and can also be isolated from cell culture media. They contain a natural cargo including various protein and nucleic acid molecules originated from their donor cells. In recent years, exosomes have emerged as a desired drug delivery system. They are believed to provide a targeted delivery of drug molecules, supplemented with their natural function. Furthermore, they have a membranous structure similar to liposomes, and that motivated researchers to apply their previous experience of drug loading into liposomes for exosomes. Herein, we discuss applied methods for the encapsulation of different drugs into exosomes, parameters affecting the incorporation of drug molecules into exosomes, characterization techniques, recent achievements, commercialization challenges and the potential future developments of exosomal drugs. Overall, while the application of exosomes as a drug delivery system is still in its infancy, they are considered to be a new class of natural nanocarriers with great potential for clinical application. Understanding of their key formulation parameters, pharmaceutical properties, in vivo behavior and applicable scale-up production will pave their way to the market. STATEMENT OF SIGNIFICANCE: Details of loading methods, characterization and biopharmaceutical properties of drug-incorporated exosomes are presented. Most parameters affecting encapsulation of drugs into exosomes are mentioned to serve as a guide for future studies in this field. Moreover, challenges on the way of exosomes to the market and clinic are described.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Cargo biological component is fulfilled in exosomes through incubation, sonication, freeze-thaw cycling, extrusion, and electroporation once extracted from donor cells.

    “Thus far, the cargo biological component is fulfilled in exosomes through incubation, sonication, freeze-thaw cycling, extrusion, and electroporation once extracted from the donor cells [22].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
