Detection of MicroRNAs in extracellular vesicles secreted by umbilical cord-derived mesenchymal stem cells

In this study, we expanded umbilical cord-derived MSCs (UCMSCs) for EV release. Additionally, we evaluated the expression level of several microRNAs in three EV populations, including apoptotic bodies (AB), microvesicles (MV), and exosomes (EX). The results show that UCMSCs released three EV types: AB, MV, and EX into culture media.
