| Research Abstract |
The aims of this study were to investigate the mechanical-stress-induced gene expression patterns by gene profiling using microarray analysis in the cells of periodontal tissue, and to select the functionally effective molecules to regulate the bone remodeling, and then to establish the transfer method of selected gene into the periodontal tissue. The expression pattern analysis suggested that both properties common among cells and cell-specific properties affect the remodeling mechanism of periodontal tissues in response to mechanical stress. Moreover several signal pathways were identified as candidates. A non-viral gene delivery approach with nano/microbubbles and ultrasound were established for targeting soft tissues.
