The effect of mesenchymal stromal cell‐derived exosomes (Exo) and/or lipopolysaccharide (LPS) on mediator release. This measure is the opposite of the proliferation rate. The mean ± SEM of IL‐6 (a), TGF‐β (b), and IL‐10 (c) levels in dendritic cell (DC) culture supernatants after 72 hr were measured by an enzyme‐linked immunosorbent assay in n = 3 independent experiments. *p < .05, **p < .01, and ***p < .001. IL, interleukin; SEM, standard error of the mean; TGF‐β, transforming growth factor‐β
