dc.description.abstract | Purpose: This study aimed to investigate the in vitro and in vivo bone-forming potential of a sandblasted, large-grit, acid-etched (SLA) titanium (Ti) surface treated with a laminin-derived functional peptide, PPFEGCIWN (DN3). Materials and Methods: Human osteoblast-like MG63 cells were cultured with SLA Ti disks that were untreated or treated with DN3 or a control scrambled peptide. Cell adhesion, spreading, and viability on the disks were tested. Alkaline phosphatase gene expression and enzyme activity were also evaluated. Four DN3-coated SLA Ti implants and four untreated implants were placed into the tibiae of two rabbits (two implants/tibia). Ten days later, the bone-implant interfaces were subjected to histomorphometry to measure the bone response. The surface properties of the disks and implants were determined using scanning electron, widefield confocal, and confocal laser microscopy and x-ray photoelectron spectroscopy. Results: The peptide-treated and untreated disks and implants were similar in terms of physical surface properties, but the peptide-treated surfaces had significantly higher nitrogen levels (P < .05). The DN3 peptide promoted cell adhesion, spreading, and alkaline phosphatase expression and enzyme activity (P < .05). Histomorphometry of the harvested implants showed rapid bone formation and affinity of the motif. Conclusion: This study suggests that treatment with the cell adhesion peptide DN3 promotes bone healing at the SLA Ti surface. | - |
