Fig. 8From: Small extracellular vesicles from dental follicle stem cells provide biochemical cues for periodontal tissue regenerationA proposed underlying mechanism of DFSCs-sEVs-mediated promotion of periodontal tissue repair and regeneration. DFSCs-sEVs promoted the formation of new periodontal ligament-like structures and new bone in the defective periodontal tissues in rats by promoting the proliferation of PDLSCs through activation of the p38 MAPK signalling pathwayBack to article page
