Nonetheless, the field is at the moment facing challenges such as the insufficient release of exosomes, their heterogeneity and reproducibility of isolation. These concerns may be overcome via the development of artificial extracellular vesicles (EVs). Cell-derived mimetic nanovesicles (M-NVs) may be generated from a lot of cell lines with benefits including, reproducibility, big scale production, uniformity, expense effectiveness plus a simple purification approach. While several research have shown that M-NVs have similar morphology, size and therapeutic potential to exosomes, complete characterization and to what extent these artificial EV elements mimics exosomes stay elusive. Techniques: In this study, M-NVs generated by FCGR2A/CD32a Proteins Biological Activity subjecting cells to the extrusion, have been comprehensively characterized and compared to the exosomes by proteomic and transcriptomic analysis. Benefits: We analysed the proteome in between M-NVs and exosomes to provide essential insights into crucial membrane surface capabilities of exosomes for cargo sorting and therapeutics delivery are preserved in M-NVs (158 proteins). In addition, our study highlighted variations in protein post-translational modifications amongst M-NVs, as distinct from exosomes, employing a non-targeted informatic method, particularly showing phosphorylation, ubiquitination, and thiophosphorylation as enriched protein modifications in M-NVs. Tiny RNA analysis reveals that in contrast to exosomes, the RNA cargo of M-NVs is equivalent to that with the parental cells. Moreover, we found that M-NVs might be useful for packaging proteins or RNA that are globally enriched in cells. Certainly, this may possibly overcome the challenges involved in selective packaging of therapeutic proteins or RNAs into exosomes.JOURNAL OF EXTRACELLULAR VESICLESSummary/Conclusion: In summary, results from this study gives crucial insights into omics of M-NVs cargo in comparison to exosomes and eventually its potential as therapeutic delivery program.
