Minimum information for studies of extracellular vesicles (MISEV) as toolbox for rigorous, reproducible and homogeneous studies on extracellular vesicles

This is the authors' abstract. We don't add key points for this paper.

Studies based on extracellular vesicles (EVs) have been multiplying exponentially for almost two decades, since they were first identified as vectors of cell-cell communication. However, several of these studies display a lack of rigor in EVs characterization and isolation, without discriminating between the different EV populations, thus generating conflicting and unreproducible results. There is therefore a strong need for standardization and guidelines to conduct studies that are rigorous, transparent, reproducible and comply with certain nomenclatures concerning the type of EVs used. The International Society for Extracellular Vesicles (ISEV) published the Minimum Information for Studies of Extracellular Vesicles (MISEV) in 2014, updating it in 2018 and 2023 to reflect different study contexts and technical advancements. The primary objective of this review is to inform future authors about EVs, including their history, nomenclature, and technical recommendations for the for isolation and functionality analysis for conducing EV-based studies according to current standards. Additionally, it aims to inform reviewers about the key parameters required for characterizing EV preparations. • Guidelines for future authors regarding the standards for conducting EV-based studies. • A comprehensive guide outlining the minimum information necessary for EV-based research. • An informative resource for reviewers on the current standards within the EV field.
