Finally, we measured the expression of FGF10 and its ligand FGFR2 by Western blotting, and found that the expression of FGF10 was significantly increased in LPS-induced ALI (p < 0.05), but the expression of the FGF10 receptor did not significantly change (Figure 1F and 1G). This evidence concerns the gene FGF10 and acute respiratory distress syndrome.
