Triple SMSC differentiations. Osteogenic, chondrogenic, and adipogenic differentiation of SMSCs from RA patients and HDs were observed using an inverted phase-contrast microscope. (a) Osteogenic differentiation was indicated by mineralization nodes stained with alizarin red (scale bar: 200 μm). (b) Chondrogenic differentiation was identified by glycosaminoglycans stained with toluidine blue (scale bar: 200 μm). (c) Adipogenic differentiation was identified by lipid vacuoles stained with oil red O (scale bar: 200 μm).
