Abstract EN
Exosomes secreted by mesenchymal stem cells (MSCs) have shown repairing effects on several tissue injury diseases.
In this study, we aimed to investigate the effects of exosomes released from human umbilical cord mesenchymal stem cells (hucMSCs) on the treatment of dextran sulfate sodium- (DSS-) induced inflammatory bowel disease (IBD) and to explore the underlying mechanism.
We found that indocyanine green (ICG) labeled exosomes homed to colon tissues of IBD mice at 12 hours after injection.
Exosomes significantly relieved the severity of IBD in mice as hucMSCs.
The expression of IL-10 gene was increased while that of TNF-α, IL-1β, IL-6, iNOS, and IL-7 genes was decreased in the colon tissues and spleens of exosomes-treated mice.
Furthermore, the infiltration of macrophages into the colon tissues was decreased by exosome treatment in IBD mice.
In addition, we provided evidence that in vitro coculture with exosomes inhibited the expression of iNOS and IL-7 in mouse enterocoelia macrophages.
Moreover, we found that the expression of IL-7 was higher in the colon tissues of colitis patients than that of healthy controls.
Our findings suggest that exosomes from hucMSCs have profound effects on alleviating DSS-induced IBD and may exert their impact through the modulation of IL-7 expression in macrophages.
