Fig. 11From: Differential pulmonary effects of CoO and La2O3 metal oxide nanoparticle responses during aerosolized inhalation in miceInterstitial fibrosis in lungs of La2O3 nanoparticle-exposed mice. Higher power magnification and Picrosirius red (PSR) staining demonstrate a small focus of interstitial fibrosis in a La2O3 nanoparticles exposed animal at 56 days post exposure. n = 12 male mice per groupBack to article page
