Lung fibroblast clones from normal and fibrotic subjects differ in hyaluronan and decorin production and rate of proliferation

Development of fibrosis involves an increase in the deposition of connective tissue components including collagens, fibronectin and proteoglycans. One hypothesis to account for matrix deposition in fibrosis is that fibroblast with differing matrix producing capacity are involved in the fibrotic process. To test this hypothesis, primary fibroblast cultures and clones derived from these primary lines were established from the lung tissue of …
