Abstract (original English)
Objective: To explore the protective effect of human adipose-derived mesenchymal stem cells (AD-MSCs) and liraglutide on lipopolysaccharide (LPS) -induced acute lung injury (ALI) . Methods: AD-MSCs were cultured in vitro and randomly divided into 3 groups: control group, LPS group (30 mg/L) , and LPS (30 mg/L) +liraglutide (10 nM) group. MTT assay was used to detect the proliferation of AD-MSCs at 6, 24, 48 and 72 h. Annexin V-FITC / PI double staining flow cytometry was used to detect the apoptosis of the cells. Western blot was used to detect the expression of apoptotic proteins cleaved caspase-3, Bax and Bcl-2 at 72 h in vitro . For the in vivo experiment, 60 male SPF BALB/c mice were randomly divided into 5 groups: control group, ALI group, ALI+AD-MSCs group, ALI+Liraglutide group, and ALI+AD-MSCs+Lraglutide group. The mice were sacrificed on day 2 and day 7 after LPS treatment. HE staining was used to examine the pathological changes of the lungs of mice, and the scores of lung injury were measured. The lung tissues of mice were examined by immunohistochemistry, and the expression of the marker protein Nanog of mesenchymal stem cells was observed. BALF was collected, and the number of BALF neutrophils was counted by Rayleigh Giemsa staining. The wet/dry specific gravity of mouse lung tissue was recorded. Results: The apoptosis of AD-MSCs stimulated by LPS was significantly
What this study does not prove
