Fig. 6From: Small extracellular vesicles derived from Nrf2-overexpressing human amniotic mesenchymal stem cells protect against lipopolysaccharide-induced acute lung injury by inhibiting NLRP3Nrf2-sEVs inhibit NLRP3 expression in macrophages. A Representative immunofluorescence images of lung tissue showing double-labeling of NLRP3 (green) and the murine macrophage marker, F4/80 (red). Scale bar = 100 μm. B, C Quantification of NLRP3 (B) and F4/80 (C) levels using the mean optical density (MOD). n = 5 mice per group. Data are presented as mean ± SD. *p < 0.05, **p < 0.01 versus sham, and #p < 0.05, ##p < 0.01 versus LPS + PBS groupBack to article page
