Therapeutic effect of human umbilical cord mesenchymal stem cells and their conditioned medium on LPS-induced endometritis in mice
Tissue and Cell(2024)
摘要
Aim
To explore the effect of human umbilical cord mesenchymal stem cells (hUC-MSCs) and their conditioned medium (MSC-CM) in repairing the endometritis mouse model in vivo.
Methods
Lipopolysaccharide (LPS) was used to induce acute inflammation in endometritis mouse model. Mice were treated in six groups: control group (PBS), model group (LPS), LPS+MSC-CM (6h) group, LPS+MSC-CM (12h) group, LPS+MSCs (6h) group and LPS+MSCs (12h) group. Morphological and histological changes of mouse uterus were observed, and mouse uterine inflammation index myeloperoxidase (MPO) and related immune index TNF-α、IL-6 and IL-1β levels were detected by ELISA. Results:There exist remarkable inflammatory response and an obvious increase in the value of MPO, TNF-α, IL-1β and IL-6 in the endometritis mouse model compared with the control group. Morphological and histological appearances were relieved after treated with hUC-MSCs and MSC-CM. Besides, the value of MPO, TNF-α, IL-1β and IL-6 showed different degrees of decline. In comparison with LPS+MSC-CM (12h) and LPS+MSCs (12h) group, there was significant decrease in inflammatory indicators in LPS+MSC-CM (6h) and LPS+MSCs (6h) group.
Conclusions
Intrauterine infusion of hUC-MSCs and MSC-CM can alleviate LPS induced endometritis.
