Western blot analysis of HGF in lung tissue. Lung homogenates from 4 patients (2 patients with emphysema [E] and 2 non-emphysema patients [NonE]). Recombinant human HGF (R&D Systems: according to the manufacturer, rhHGF is a mixture of proHGF and cleaved mature HGF) was loaded and blotted in parallel. HGF was in the cleaved mature form as evidenced by the detection of the 69-kD α chain and the absence of the 90-kD proHGF form.
