英文摘要
Recently much attention has been paid to periodontal tissue regeneration using mesenchymal stem cells and biodegradable scaffolds. One of the most important challenges at this moment is to accelerate the formation of new bone tissues. In this study, we screened various growth factors and their combinations to identify the best factors to be incorporated into scaffolds for the enhanced bone formation. As a result, we found that incorporation of BMP-2 into scaffold materials is most effective for the preparing bone tissue scaffolds. Further study was carried out to identify peptides that have an affinity for biodegradable polymer scaffolds. As a result, it was found that the peptide having a specific sequence exhibited an affinity for poly(lactic acid). According to this result, we propose that, when fused with a growth factor, this peptide would be effective for constructing growth factor/scaffold composites.
