Characteristics of human PDLSCs. (A) Primary PDLSCs (Scale bar: 200 μm). (B) Alizarin Red S staining for osteogenic differentiation (scale bar, 100 μm). (C) Alcian blue staining for chondrogenic differentiation (scale bar, 100 μm). (D) Oil Red O staining for adipogenic differentiation (scale bar, 50 μm). (E) Flow cytometric analysis demonstrating that PDLSCs were positive for the mesenchymal stem cell (MSC) markers CD44, CD90, CD73 and CD105 and negative for the hematopoietic stem cell (HSC) marker CD45.
