HGF concentration in BAL neutrophils culture supernatants from patients with idiopathic pulmonary fibrosis (IPF) and connective tissue disease-associated pulmonary fibrosis (CTD-PF). Individual values. Neutrophils were purified and cultured for 20 hours (107/ml per well) in basal conditions or with LPS stimulation (1 μg/ml) (LPS). HGF concentrations were not different in each group.
