2nd Virtual Symposium: Urinary EVs: 15-16 February, 2023

Thank you to all who attended the uEVs2023 meeting! Check back later for a recap of the meeting. 

uEV2023 is the second Virtual Symposium on Urinary Extracellular Vesicles. Organized by the Urine Task Force of the ISEV Rigor and Standardization Subcommittee, the meeting brings together the global community studying extracellular vesicles in urine. This virtual symposium features state of the art presentations, technical updates from Urine Task Force working groups, interactive panel discussions and poster presentations. The meeting emphasizes trainee opportunities and builds upon the welcoming environment and lively discussions of uEV2022. The uEV2023 is a must-attend for nephrologists, urologists, cell and molecular biologists, biobank experts, and anyone studying urinary extracellular vesicles.
