ABSTRACT
Idiopathic pulmonary fibrosis (IPF) is a rare interstitial lung disease with a poor prognosis. Chronic microinjuries, mainly caused by environmental factors to an aging alveolar epithelium, would lead to the aberrant differentiation and accumulation of aberrant mesenchymal cells with a contractile phenotype, known as fibrosis-associated myofibroblasts, which trigger abnormal extracellular matrix accumulation and fibrosis. The origin of those pathological myofibroblasts in pulmonary fibrosis is not fully understood to date. Lineage tracing methods using mouse models have opened new avenues for studying cell fate in a pathological context. This review aims to present a nonexhaustive list of different potential sources of those harmful myofibroblasts during lung fibrosis, based on these in vivo approaches, and considering the normal and fibrotic lung cellular atlas recently established by single-cell RNA sequencing.
