Characterization of apoptotic bodies from MSCs (MSC-ABs). a The schematic graph shows the protocol of isolation of MSC-ABs. b Representative image of SEM analysis of MSC-ABs. Scale bar, 1 μm. c Size distribution of MSC-ABs measured by DLS. d Representative images of C1q and Annexin V staining of MSC-ABs. Scale bar, 20 μm. e The protein level of caspase-3 for MSC-ABs examined by western blots
