| Research Abstract |
Both the epithelial cells of Malassez and periodontal ligament fibroblasts were co-cultured in the same dish. The interactions between the epithelial cells of Malassez and periodontal ligament fibroblastscurrent induceed the expression of amelogenin, ameloblastin, MMP-20 and KLK 4 in the epithelial cells of Malassez.
We also showed that the epithelial cells of Malassez which incorporated BrdU expressed Bax strongly in co-cultured cells, suggesting that the epithelial-mesenchymal interactions enhance cell turnover in the epithelial cells of Malassez.
These results indicate that epithelial-mesenchymal interactions may induce cell turnover and cellular cementum formationin in the epithelial cells of the rests of Malassez.
