| Outline of Final Research Achievements |
In this study, we demonstrated that the expression of bone morphogenetic protein-1 (BMP-1), CCN family member 2/connective tissue growth factor (CCN2/CTGF), and dentin sialophosphoprotein (DSPP) was accelerated in the layer of odontoblast-like cells and reparative dentin subjacent dental caries in human teeth. BMP-1 induced the expression of CCN2/CTGF independently of protease activity in the human dental pulp cells but not that of DSPP or dentin matrix protein-1 (DMP-1). Furthermore, cell membrane glycosylation was altered by BMP-1 stimulation as analyzed by lectin microarray.
These findings indicate that a novel property of BMP-1 which potentially enhances bone-like reparative dentin formation through CCN2 expression and membrane glycosylation in dentin-pulp complex.
