Fig. 2From: Osteocyte-derived exosomes induced by mechanical strain promote human periodontal ligament stem cell proliferation and osteogenic differentiation via the miR-181b-5p/PTEN/AKT signaling pathwayEffects of Exosome-MS on the proliferation of HPDLSCs. The cell proliferation ability of HPDLSCs treated with Exosome or Exosome-MS together with or without Pg LPS. a The cell proliferation curve of HPDLSCs from day 0 to day 4. b The OD values are shown for each group. c EdU staining was used to reflect DNA replication activity of HPDLSCs (scale bar 100 μm). d EdU-positive percentage was calculated by ImageJ in different treatment groups (*P < 0.05, **P < 0.01, and ***P < 0.001)Back to article page
