Multiomics reveal human umbilical cord mesenchymal stem cells improving acute lung injury via the lung-gut axis

Figure 9 Extent of correlation between lung metabolites and bronchoalveolar lavage fluid microflorae. A: Top 25 lung metabolites and top 25 bronchoalveolar lavage fluid (BALF) microflorae were analyzed by the two-way Orthogonal Partial Least Squares analysis. A larger absolute value in a coordinate indicates a greater degree of association. Circles represent metabolites in lung tissues and squares represent microflora in BALF; B: The number of lung metabolites which were related with BALF microflorae; C: Kyoto Encyclopedia of Genes and Genomes enrichment analysis of top 25 BALF microflorae with strong association. KEGG: Kyoto Encyclopedia of Genes and Genomes; BALF: Bronchoalveolar lavage fluid.
