| Research Abstract |
Transcriptome analysis of FGF-2-induced periodontal regeneration in beagle model revealed that several genes (PLXNC1, SMOC1, SMOC2, TNS3, NPNT, SPON1, WDHD1, etc.) can play important roles in osteogenic differentiation of mesenchymal stem cells. In addition, periodontal ligament specific splicing isoform of Periostin was found. On the other hand, PLAP-1, periodontal ligament specific molecule, has an asparagine acid repeat polymorphism. Importantly, these molecular differences affected their abilities to regulate differentiation of periodontal ligament cells. These results suggest that these genes may play important roles in predicting outcomes of regenerative therapy for periodontal tissue.
