Abstract:

Mitochondria-rich extracellular vesicles (mitoEVs) are increasingly recognized as key modulators of cellular metabolism and tissue repair, yet their study has been hindered by the lack of sensitive and quantitative detection strategies. Here, we introduced a nanoflow cytometry (nano FCM)–based analytical platform enabling rigorous quantification and phenotypic characterization of mitoEVs. By integrating refined instrument calibration, systematic reagent validation, and a streamlined EV isolation procedure, we achieved reliable detection of mitochondria-associated signatures within defined vesicle populations. This workflow delivered a robust and scalable framework that enhanced mitoEV analysis and supported future applications in mechanistic research and therapeutic development.
