Rigor and reproducibility: status and challenges for single vesicle analysis

Area of Science:

• Biomedical research
• Extracellular vesicle (EV) biology
• Biomarker discovery

Background:

• Progress in extracellular vesicle (EV) research is hindered by a lack of standardized, reproducible measurement tools.
• EVs hold significant potential for disease understanding, diagnosis, treatment, and prevention, necessitating robust analytical methods.
• The SELECTBIO Workshop addressed critical challenges in EV research rigor and reproducibility.

Purpose of the Study:

• To summarize key discussions and activities from the SELECTBIO Workshop on Rigor and Reproducibility in EV Research.
• To emphasize the importance of standardized guidelines, such as MISEV2018 and MIFlowCyt-EV, for EV characterization.
• To identify future directions for improving EV measurement technologies and their clinical application.

Main Methods:

• Workshop presentations and activities focused on guidelines for EV measurement and characterization.
• Discussions covered the implementation of MISEV2018 and MIFlowCyt-EV guidelines in practice.
• Consideration of evolving EV measurement technologies and their impact on research.

Main Results:

• The workshop underscored the critical need for rigorous and reproducible EV measurement tools.
• Current progress in EV research is limited by the availability and standardization of these tools.
• The need for enhanced focus on pre-analytical variables and benchmarking of EV isolation methods was identified.

Conclusions:

• Further efforts in standardizing pre-analytical procedures are essential for the EV field.
• Benchmarking of EV isolation methods is crucial for strengthening collaborations and advancing biomarker discovery.
• Improved rigor and reproducibility in EV research will accelerate clinical translation for disease management.
