Abstract
Extracellular vesicles (EVs) released by a variety of cell types have been shown to actas a natural delivery system for bioactive molecules such as RNAs and proteins. EVtherapy holds great promise as a safe and cell-free therapy for many immunologi-cal and degenerative diseases. However, translation to clinical application is limitedby several factors, including insufficient large-scale manufacturing technologies andlow yield. We have developed a novel drug delivery platform technology, BioDrone™,based on cell-derived vesicles (CDVs) produced from diverse cell sources by using aproprietary extrusion process. This extrusion technology generates nanosized vesi-cles in far greater numbers than naturally obtained EVs. We demonstrate that theCDVs are surrounded by a lipid bilayer membrane with a correct membrane topology.Physical, biochemical and functional characterisation results demonstrate the poten-tial of CDVs to act as effective therapeutics. Umbilical cord mesenchymal stem cell(UCMSC)-derived CDVs exhibit a biological activity that is similar to UCMSCs orUCMSC-derived EVs. Lastly, we present the establishment of a GMP-compliant pro-cess to allow the production of a large number of UCMSC-CDVs in a reproduciblemanner. GMP-compliant manufacturing of CDVs will facilitate the preclinical andclinical evaluation of these emerging therapeutics in anti-inflammatory or regener-ative medicine. This study also represents a crucial step in the development of thisnovel drug delivery platform based on CDVs.
