Figure 3
Scanning electron microscopy (SEM) illustrating the attachment of hPDLSCs on laser treated implants (a) and acid etched implants (c) before induction of osteogenic differentiation. Cells illustrated typical mesenchymal stem cells’ appearance (b, d) on both types of implants where the cell size was large (yellow box), stellate in shape and rich in filopodia (arrow) (magnification: (a) ×100, (b) ×16, (c) ×12, (d) ×16).
