These structures play an important role in endocytosis processes and can be identified in type I alveolar epithelium cells GilKasper etal. In vitrosuch changes are associated with changes in cell phenotype and by inference, changes in the cells susceptibility to mechanical injury. New York, Plenum Press, How to cite this article.

Recent data also suggest that the integrity of the heparan-sulfate proteoglycan components of the pulmonary ECM is required to maintain the three-dimensional architecture of the matrix itself, which in turn, ensures its mechanical response to increased fluid filtration Negrini et al.
