Characterization of plasma exosomes. A Representative results of the transmission electron microscope (TEM) demonstrate the morphology and size of exosomes. B Representative results of nanoparticle tracking analysis (NTA) demonstrate similar size distribution of exosomes in RIPC and control groups. C–D Average concentration and size of exosomes in control exosomes and RIPC exosomes. E Representative Western blots showing the expression of CD63, TSG101 and HSP90. F Relative expression of CD63, TSG101 and HSP90. The results are represented by mean ± standard deviation \(\stackrel{-}{(x}\pm s\)). *Ρ < 0.05 versus CON-Exo; n = 3 for each group
