Origins of pathological myofibroblasts in lung fibrosis: insights from lineage tracing mouse models in the single-cell RNA sequencing era

Abstract excerpt

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...
