| Outline of Final Research Achievements |
This study approached from a variety of angles which focus on interface of the dental implants and the alveolar bone. New knowledge was obtained it about growth factors affect the proliferation and differentiation of mesenchymal cells.
1. Six human periodontal ligament (HPDL) cell lines were picked up, TGF-β and BMP regulated osteoblastic differentiation of all cell lines. 2. Intracellular TGF-β was activated by MMPs enhanced in HPDL cells by Er:YAG laser irradiation. 3. We identified TGF-β isoforms in porcine immature and mature enamel of developing teeth. These results suggest that TGF-β1 is predominant in the secretory-stage enamel, while both TGF-β1 and β3 coexist in the maturation-stage enamel. 4. We established cell lines from porcine dental pulp and examined the effects of BMP2 and TGF-β on the odontoblastic differentiation. After differentiation, odontoblastic cells were expressed the gene of DSPP and MMP-20.
