Images of β-TCP and PDLSCs/β-TCP constructs with or without hOPG transfection were evaluated by SEM. (A) Image of β-TCP under SEM. (B, C) The PDLSCs adhered and extended on β-TCP surface after 2 days of culture. (D, E) The PDLSCs grew in number to link flakiness on the β-TCP surface and in the pore of the scaffold material after 7 days of culture. Magnifications: 40× (A, B, D) and 400× (C, E). β-TCP, beta-tricalcium phosphate; hOPG, human osteoprotegerin; PDLSC, periodontal ligament stem cell; SEM, scanning electron microscope.
