Investigation of Aberrant Basaloid Cells in a Rat Model of Lung Fibrosis.

Background: Idiopathic pulmonary fibrosis (IPF) is a chronic and progressive interstitial lung disease (ILD) whose cause and pathogenesis are not yet well understood. Until now, no animal model of lung fibrosis succeeds in recapitulating all IPF features, thus the use of different rodent models is essential for the evaluation and development of new effective pharmacological treatments. Recently, the alveolar epithelial dysfunction has been emphasized in the etiopathogenesis context of IPF.
