Summarized light microscopic data are provided as mean (standard deviation). Parameters are defined in the text and in the methods section. Statistical analysis was based on a two-way ANOVA taking the factors genetics (G: ctrl vs. Nedd4-2−/−) and time (T: weeks) as well as the interaction (Inter) of these factors into account. p-values below 0.05 were considered as statistically significant. Abbreviations: V: volume; par: lung parenchyma; sep: interalveolar septa; air: acinar airspaces; cons: consolidated lung parenchyma.
