The purpose of this study was to evaluate the enhancing effect of recombinant platelet derived growth factor on human mesenchymal stem cells (hMSCs) in secondary alveoloplasty. Three patients with 4 alveolar defects were selected for this study. Mesenchymal stem cells were cultured from a posterior iliac bone aspirate. MSCs were mounted on biphasic scaffolds and combined with platelet derived growth factor (PDGF) in the operating room to make a triad of the scaffold, growth factor, and cells. The triads were placed in anterior maxillary cleft defects and closed with lateral advancement gingival flaps. The postoperative cleft bone volume was measured with cone beam computed tomography scans. A mean of 51.3% fill of the bone defect was calculated 3 months post-operation. Our data suggests the use of recombinant platelet derived growth factor with hMSCs may enhance the regeneration capacity of the cells.
