Identification of uMSCs and characterization of uMSC-EVs. a, b The surface antigen (CD34, CD45, CD73, CD90, and CD105) in uMSCs was detected using FCM and IF staining, scale bar = 100 μm. c Morphological characteristics of uMSC-EVs were observed via transmission electron microscopy, scale bar = 100 nm. d Exosomal markers (CD9, CD63, and TSG101) of uMSC-EVs were detected using western blot assay. e uMSC-EV particle size was detected using NanoSight. FCM, flow cytometry; IF, immunofluorescence staining; uMSCs, umbilical cord-derived mesenchymal stromal cells; uMSC-EVs, umbilical cord-derived mesenchymal stromal cell-derived extracellular vesicles
