Figure 3From: Autophagy in periodontitis patients and gingival fibroblasts: unraveling the link between chronic diseases and inflammation Ultrastructure of lipopolysaccharide-treated human gingival fibroblasts (10 μg/mL). Control fibroblasts show mitochondria with typical ultrastructure. Laminar bodies and autophagosome with mitochondria were present in LPS-treated fibroblasts (black arrow); Bar = 500 nm. LPS: lipopolysaccharide.Back to article page
