Idiopathic pulmonary fibrosis (IPF) remains a disease with an unknown cause and a poor prognosis. Among attempts to define disease pathogenesis, animal models of experimental lung fibrosis have a prominent role. Commonly used models include exposure to bleomycin, silica, fluorescein isothiocyanate; irradiation; or expression of specific genes through a viral vector or transgenic system. These all have been instrumental in the study of lung fibrosis, but all have limitations and fall short of recapitulating a pattern of usual interstitial pneumonia, the pathologic correlate to IPF. A model of repetitive bleomycin lung injury has recently been reported that results in marked lung fibrosis, prominent alveolar epithelial cell hyperplasia, a pattern of temporal heterogeneity and persistence of aberrant remodeling well after stimulus removal, representing a significant addition to the collection of animal lung fibrosis models. Taken together, animal models remain a key component in research strategies to better define IPF pathogenesis.
