Exosomes are now considered an important subcategory of extracellular vesicles (ECVs) that contain a core of micro-RNA (miRNA), messenger-RNA (mRNA), transcription factors, membrane-trafficking proteins, antigen-presenting proteins, and other peptides protected within a bilayer lipid membrane. To date, exosomes have displayed a plethora of prospective clinical applications, including stem cell maintenance and plasticity, biomarkers, adjuncts in chemotherapy and drug delivery, and wound healing supplements that promote angiogenesis.
