Pulmonary fibrosis, represented mainly by idiopathic pulmonary fibrosis, develops chronic and progressive changes in lung parenchyma with high mortality and limited therapeutic options. The aim of this review was to summarize the most common experimental models used in the research of pulmonary fibrosis. Lung damage associated with development of pulmonary fibrosis can be caused by irradiation or by instillation of bleomycin, fluorescein isothiocyanate (FITC), silicon dioxide (silica), asbestos, etc. This article reviews the characteristics of the most frequently used animal models of fibrosis, including the limitations of their use. Although none of the used animal models resembles completely the changes in human pulmonary fibrosis, similarities between them allow preclinical testing of novel treatment approaches or their combinations in the laboratory conditions before their use in the clinical practice.
