Objective · To evaluate the feasibility of immature permanent teeth pulp regeneration with a new method that utilizes the integration of concentrated growth factor (CGF) as a scaffold and stromal cell-derived factor-1 (SDF-1). Methods · Canine dental pulp cells (DPC) were isolated and cultured in vitro. Then the effects of SDF-1 and CGF were observed on DPC proliferation and differentiation. The pulpless model was established on the beagle’s immature incisors which were divided into four groups: natural pulp (A), empty cannel (B), CGF-filling (C) and SDF-1/CGF-filling (D). After 10 weeks, specimens were checkedimaging examination, RT-PCR and histological observation. Results · CGF extraction (CGFe) induced DPC proliferation while the combination of SDF-1 and CGFe enhanced this effect and also facilitated odontogenic and angiogenic differentiation of DPC. According to imaging examination, the apex growth of all four groups was in varying degrees. RT-PCR indicated the s of odontogenesis and angiogenesis related genes in group D were higher than those in group C. Besides, neonatal dentin and dental-pulp-like tissue were observed inside the canal of both group C and D, while only cementum-like tissue existed around root apex of group B. Conclusion · SDF-1 plays an important role in driving the process of pulp-like-tissue regeneration of immature permanent teethusing CGF as an effective scaffold.
