Background. Discovering suitable seeding cells and simple application technique will be beneficial for MSC-mediated treatment of periodontitis. Stem cells from apical papilla (SCAPs) might be the candidate seeding cell for the periodontal tissues regeneration based on their origin and characters. In this research, we investigated the effect of SCAPs on periodontal tissue regeneration in swine by local injection. Methods. We established experimental periodontitis model in miniature pigs and then treated them with SCAPs by local injection. Clinical assessments, computed tomography (CT) scanning, histologic examination, and quantitative measurements were used to evaluate the effect of periodontal tissues regeneration. Results. At 12 weeks after injection, clinical assessments showed that probing depth, gingival recession, and attachment loss values were 5.44±0.77 mm versus 7.33±1.0 mm (p<0.01), 2.33±0.33 mm versus 2.11±0.69 mm (p>0.05), and 7.78±0.84 mm versus 9.44±1.07 mm (p<0.01) in SCAPs group and 0.9% NaCl group, respectively. CT scan results showed a significant increase of 12.86 mm3 alveolar bone regeneration in SCAPs group compared with 0.9% NaCl group. In addition, histopathology results demonstrated remarkable regeneration in SCAPs group, whereas regeneration of periodontal tissue was hardly found in 0.9% NaCl group. Conclusion. Local injection of SCAPs could effectively restore tissue defects brought about by periodontitis in the swine model. Thus, SCAPs, as an easily accessible dental-deriving stem cell, may serve as an alternative application for periodontitis treatment.

Abstract Tissue engineering in the head and neck area, presents numerous advantages. One of the most remarkable advantages is that regeneration of only a small amount of tissue can be highly beneficial to the patient, particularly in the field of periodontal tissue regeneration. For decades, successful osseointegration has provided thousands of restorations that maintain normal function. With the increasing need to utilize dental implants for growing patients and enhance their function to simulate normal tooth physiology and proprioception, there appears to be an urgent need for the concept of periodontal tissue regeneration around dental implants. In the present work, 5 goats were used for immediate implant placement post canine teeth extraction. Each goat received 2 implant fixtures; the control side received a porous hollow root-form poly (DL-Lactide-co-Glycolide) scaffold around the titanium fixture, and the experimental side received the same scaffold but seeded with autogenous bone marrow–derived mesenchymal stem cells. One animal was killed 10 days postoperatively, and the others were killed after 1 month. The results showed that on the experimental side, periodontal-like tissue with newly formed bone was demonstrated both at 10 days and after 1 month, while the control specimens showed early signs of connective tissue regeneration around the titanium fixture at 10 days, but was not shown in the 1 month specimens. It can be concluded that undifferentiated mesenchymal stem cells were capable of differentiating to provide the 3 critical tissues required for periodontal tissue regeneration: cementum, bone, and periodontal ligament. This work may provide a new approach for periodontal tissue regeneration.

Objectives. Enhanced migration and osteogenic differentiation of mesenchymal stem cells (MSCs) are beneficial for MSC-mediated periodontal tissue regeneration, a promising method for periodontitis treatment. FBXO5, a member of the F-box protein family, is involved in the osteogenic differentiation of MSCs. Here, we investigated the effect of FBXO5 on human periodontal ligament stem cells (hPDLSCs). Materials and Methods. hPDLSCs were isolated from periodontal ligament tissue. Lentivirus FBXO5 shRNA was used to silence FBXO5 expression. Two transcripts of FBXO5 were overexpressed and transduced into hPDLSCs via retroviral infection. Migration and osteogenic differentiation of hPDLSCs were evaluated using the scratch migration assay, alkaline phosphatase (ALP) activity, ALP staining, alizarin red staining, western blotting, and real-time polymerase chain reaction. Results. The expression of FBXO5 was upregulated after osteogenic induction in hPDLSCs. FBXO5 knockdown attenuated migration, inhibited ALP activity and mineralization, and decreased RUNX2, OSX, and OCN expression, while the overexpression of two transcript isoforms significantly accelerated migration, enhanced ALP activity and mineralization, and increased RUNX2, OSX, and OCN expression in hPDLSCs. Conclusions. Both isoforms of FBXO5 promoted the migration and osteogenic differentiation potential of hPDLSCs, which identified a potential target for improving periodontal tissue regeneration.
