What is it about?
The prognosis of elderly individuals with idiopathic pulmonary fibrosis (IPF) remains poor with a 5-year survival rate worse than several types of cancer. Fibroblasts are central to the progression of pulmonary fibrosis. The pathological hallmark lesions in IPF comprise fibroblastic foci in fibrotic lesions in which aggregates of proliferating fibroblasts and myofibroblasts are involved. Their diversity in fibroblasts makes it difficult to understand the pathogenesis of pulmonary fibrosis. Our study was aimed to determine the role of fibroblasts positive for meflin, identified as a potential marker for mesenchymal stromal cells, during the development of pulmonary fibrosis.

Why is it important?
Our data show that; 1) meflin expression appeared to be abundant and almost restricted in pulmonary fibroblasts, 2) meflin-positive fibroblasts were localized in fibroblastic foci, not in dense fibrosis, in IPF lungs, 3) pulmonary fibroblasts positive for meflin had anti-fibrotic property to prevent pulmonary fibrosis.
