Fig. 2From: Mesenchymal stem cell-derived extracellular vesicles attenuate influenza virus-induced acute lung injury in a pig modelMesenchymal stem cell extracellular vesicles (MSC-EVs) express EV markers. EV-coated latex beads were examined for the expression of EV markers by flow cytometry. EVs expressed the specific EV markers CD9, CD63, and CD81 (broken line: isotype staining; solid line: specific staining)Back to article page
