From: Matrix metalloproteinase-10: a novel biomarker for idiopathic pulmonary fibrosis
The immunohistochemical expression of matrix metalloproteinase (MMP)-10 in idiopathic pulmonary fibrosis (IPF) lung tissue and control lung tissue. (a-c) The expression of MMP-10 is weakly positive in alveolar epithelial cells and macrophages in control lung tissue. (d-f) In IPF lung tissue, MMP-10 is expressed predominantly in alveolar macrophages, alveolar epithelial cells, and peripheral bronchiolar epithelial cells. The staining intensity of MMP-10 in IPF lung tissue is stronger compared with control lung tissue
