Effects of Cyclic RGD Peptide Functionalization on the Quantitative Bone Ingrowth Process in Cellularized Biphasic Calcium Phosphate Ceramics

Article Preview

Abstract:

The aim of this study was to evaluate the in vivo effects of the grafting of cyclo- DfKRG on the early phase of integration of biomaterials made with macroporous hydroxyapatite/b-tricalcium phosphate colonized with autologous bone marrow stromal cells. Non-grafted (-RGD) and grafted (+RGD) biomaterials were implanted in both femoral condyles of rabbits for 2 and 4 weeks. Two weeks after implantation, the global bone formation was higher with +RGD samples (p=0.02). There remained no significant difference 4 weeks after implantation. In conclusion, grafting of cyclo-DfKRG peptide on materials could promote cell colonization and improve osteoconduction during the first stage of the bone cicatrization process.
