From: Defective alterations in the collagen network to prostacyclin in COPD lung fibroblasts
The IP receptor is expressed by epithelial cells and fibroblasts in the lung. Representative staining is shown in bronchial lung tissue (A), parencyhmal lung tissue (B), and distal lung fibroblasts in vitro (C) from control subjects and bronchial lung tissue (D), parenchymal lung tissue (E) and distal lung fibroblasts in vitro (F) from patients with COPD. Panel (G) and (H) show isotype-matched control IgG. Scale bars are indicated as 10 μm in Figure 1A, B, D, E and G and 50 μm in panel 1 C, F and H.
