This study compared the characteristics of periodontal ligament stem cells (PDLSCs) cultured using 3-dimensional (3D) versus conventional 2-dimensional (2D) methods. PDLSCs were in either a 3D culture with non-adhesive plate (Stemfit 3D®) or 2D 6-well plate. Morphology, viability, proliferation ability, and osteogenic differentiation analyzed to characterize differences induced identical by env...
