ARTICLE HIGHLIGHTS
Research background
Acute lung injury (ALI) has high morbidity and mortality rates and needs effective treatment. Research has found that the gut microbiota improves lung injury through the lung-gut axis. Human umbilical cord mesenchymal cells (HUC-MSCs) can improve ALI.
Research motivation
Although HUC-MSCs can improve ALI, their biological mechanism of action is not yet clear.
Research objectives
To explore changes in the microbiota in the lung-gut axis and the relationship with HUC-MSC treatment.
Research methods
C57BL/6 mice were used to establish an ALI animal model by intraperitoneal injections of lipopolysaccharide. Wright’s staining, ELISA, hematoxylin-eosin staining, Evans blue dye leakage assay, immunohistochemistry, fluorescence in situ hybridization, and western blot were used to observe the improvement of ALI mice by HUC-MSCs. High-throughput 16S rDNA sequencing was used to observe the microbiota homeostases in the lung-gut axis. The non-targeted metabolomics was used to explore changes in lung tissue metabolites.
Research results
HUC-MSCs ameliorated histopathological damage in the lung and ileum of ALI mice. HUC-MSC treatment improved inflammation, endothelial barrier integrity, and bacterial translocation in the lungs and ileum of ALI mice. HUC-MSCs regulated lung-gut microbiota homeostasis. HUC-MSC treatment regulated the metabolic profile in the lung and ileum of ALI mice.
Research conclusions
This study shows the improvement of changes in the lung and ileum of ALI mice by HUC-MSCs, and suggests a correlation between HUM-MSC-improved ALI and gut and lung microbiota homeostases.
Research perspectives
This study explores the biological mechanism of HUC-MSCs in improving ALI from the perspective of the correlation between the microbiota in the lung-gut axis and lung tissue metabolites, providing a research basis for HUC-MSC treatment.
