IL-1 Receptor Antagonist Protects the Osteogenesis Capability of Gingival-Derived Stem/Progenitor Cells under Inflammatory Microenvironment Induced by Porphyromonas gingivalis Lipopolysaccharides

Figure 1

Characterization and multidirectional differentiation potential of stem/progenitor cells from rat gingival tissues. (a) Microscopic appearance of rGMSC morphology (20x). (b) Osteogenic differentiation of rGMSCs after 21 days of osteogenic induction. Positive staining of calcified deposits is observed (200x). (c) Adipogenic differentiation of rGMSCs after 21 days of adipogenic induction. Positive staining of lipid droplets is observed (200x). (d) Chondrogenic differentiation of rGMSCs after 21 days of chondrogenic induction. Positive staining of glycosaminoglycans is observed (200x).
