Sources of material for genomic analysis in pulmonary fibrosis. Genomic analysis can be performed directly on lung samples (A) or on primary cells cultured from the lung (B). Peripheral blood (C) can be drawn and genomic information can be obtained from free RNA residing in the plasma or in apoptotic bodies (D). Peripheral blood mononuclear cells (PBMC) (E) can be studied directly. Fibrocytes (F), bone marrow-derived, collagen producing cells can be isolated from PBMC and analyzed directly or following stimulation in cell culture.
