| خلاصه مقاله | Background: Endometritis is a histopathologic condition that affects the proper decidualization and implantation processes of the embryo. In this study, exosome-containing Rosmarinic acid (RA) was used to dampen lipopolysaccharide (LPS)-induced endometritis and subsequently enhance implantation.
Materials and Methods: In this study, exosomes extracted from the serum samples were loaded with RA acid and then administrated into the animal groups, including RA, exosome, RA plus exosome (RA+Exo), and RA-loaded exosomes (RALExo) groups. The concentrations of RA or exosomes used in this study was 10 mg/kg, and the compounds were injected into the uterine horn 24 hours following the induction of endometritis. Upon the presence of inflammation detected by the histopathological method, themost proper groups were mated with male mice. The effect of the treatment group on the implantation rate, progesterone levels, and gene expression was assessed by Chicago Blue staining, ELISA, and RT-PCR, respectively.
Results: According to the obtained results, RALExo10 and RA10+Exo10 groups exhibited improved pathological alterations, enhanced progesterone levels, increased implantation rate, as well as heightened expression levels of LIF and Muc-16 genes. Besides, the expression levels of inflammatory cytokines, including TGF-β and IL-10, IL-15, and IL-18, were regulated.
Conclusion: Our findings indicated that the expression of LIF, Muc-16 genes as well as IL-18, were significantly correlated with serum progesterone concentrations and the implantation rate in the treatment groups. |
