About the MISEV Guidelines

The International Society for Extracellular Vesicles (ISEV) first published its “Minimal Information for Studies of Extracellular Vesicles,” in 2014 (MISEV2014) with an updated version published in 2018 (MISEV2018).  ISEV are now proud to share the most recent version of the MISEV guidelines, MISEV2023.
The goal of MISEV 2023 is to provide researchers with an updated snapshot of available approaches and their advantages and limitations for production, separation, and characterization of EVs from multiple sources, including cell culture, body fluids, and solid tissues. In addition to presenting the latest state of the art in basic principles of EV research, MISEV 2023 also covers advanced techniques and approaches that are currently expanding the boundaries of the field. MISEV2023 includes new sections on EV release and uptake and a brief discussion of in vivo approaches to study EVs. 
Compiling feedback from ISEV expert task forces and more than 1000 researchers worldwide, MISEV 2023 conveys the current state of EV research to facilitate robust scientific discoveries and move the field forward even more rapidly.


What was the process behind MISEV2023?

The achievement of publishing MISEV2023 is the culmination of a three-year process, summarised below.  You can read more about this process in the concluding section of MISEV2023.

  • 2020 pre-MISEV survey (summary article)
  • ISEV board assigned a five-author committee (Welsh, Goberdhan, O’Driscoll, Théry, Witwer) 
  • Drafts and refinements with ISEV board input and invited drafting authors
  • 2022 co-author survey with >1000 responses
  • Revisions based on the survey 
  • Internal review and additional invited contributions/revisions; style “unification”
  • Journal pre-submission review and three post-submission reviews
  • Co-author confirmation and consensus survey


MISEV2023: domains

  • Nomenclature: communication of concepts
  • How to approach Non-Vesicular Extracellular Particles
  • Collection and pre-processing: pre-analytical variables: EV sources including bacteria, biofluids, tissue
  • EV separation and concentration
  • EV characterization
  • Technique-specific reporting for EV characterization
  • EV release and uptake
  • Functional studies
  • In vivo EV studies

New sections in MISEV2023 are highlighted in bold.

What MISEV is NOT…or should not be…

  • An unreasonable barrier to field entry 
  • Rather, a guide to doing rigorous and publishable science
  • An attempt to stifle innovation
  • See the MISEV2018 section on “exceptions”; MISEV2023 “IS NOT” section
  • Irrelevant to non-mammalian EV studies
  • Principles of good definitions, markers, and controls are relevant to all EV sources. The exact markers and procedures will vary.
  • Irrelevant to clinical studies: biomarkers, therapeutics
