  • Title: Occurrence of different types of contractile cells in some lung fibrosis.
    Author: Bondi A, Mancini AM, Baldini N.
    Journal: Appl Pathol; 1983; 1(2):66-75. PubMed ID: 6678157.
    Abstract:
    Two different morphologic patterns of pulmonary fibrosis have been identified by means of anti-actin antisera and electron microscopy. The first type, observed in chronic passive congestion and also in radiation-induced fibrosis, is characterized by hyaline alveolar walls, with scarce cells, mostly normal fibroblasts. The second type, on the contrary, shows a high cellularity of the alveolar walls with actin-rich cell proliferation, i.e. contractile interstitial cells in usual interstitial pneumonia and shock lung, myofibroblasts in organizing pneumonia, and smooth muscle cells in honeycomb lungs.
