HGF attenuated pulmonary vascular endothelial injury in septic mice. a Evans Blue was intravenously administered and measured in lung homogenates to assess pulmonary vascular permeability; b The total protein contents in the BALF were measured using the BCA method to assess protein leakage; c The lung weight and body weight ratio were analysed to assess lung oedema; n = 3, *P < 0.05; (D) Ultrathin lung sections were scanned using TEM to assess vascular endothelial injury by a blind observer; N indicates nuclear; pentagram indicates bubbling of pyroptotic cells; scale bar = 5 μm
