Identification of LPS pre-Exo. a Transmission electron micrograph of exosomes derived from diverse processing MSCs. Scale bar 100 nm. b Detection of CD9, CD63, and CD81 expression in MSC derived exosomes by western blotting. c UC-MSCs showed enhanced exosome secretion after LPS preconditioning. Data are presented as the mean ± SEM of three separate experiments. d Fluorescence microscopy detection of the uptake of Dil-labeled exosomes (red) by THP-1 cells (Hoechst blue) for 6 h. Scale bars 50 µm
