项目摘要

To investigate the mechanisms that periodontopathic bacteria cause periodontal tissue destruction we established the three-dimensional co-culture gingival epithelial cell and fibroblast) system using PIPAAm. Gingival epithelial cells were seeded to Rep Cell plate (CellSeed, Tokyo) and were incubated to confluent. Then, epithelial cells were incubated at 32℃ for 30 min. After the incubation epithelial cells were removed as a cell sheet. Then the epithelial cell sheet was placed onto fibroblasts cultured in type 1 collagen. After co-culture of epithelial cells and fibroblasts for a week, we obtained the three-dimensional gingiva-reconstructive culture mimic to periodontal pockets. We compared the expression of claudin, cadherin, JAM-1, component of tight junction and adherence junction, in normal gingival to that of the three-dimensional gingiva-reconstructive culture. The expression pattern of claudin, cadherin, and JAM-1 in the three-dimensional gingiva-reconstructive culture was identical to that of normal gingival.Then, we examined the expression pattern of claudins in human periodontal pockets. In human periodontal pockets claudins-1, 4, 7, 12 were expressed constitutively. Moreover, those claudins were detected in three-dimensional gingiva-reconstructive culture. This data suggested that our three-dimensional gingiva-reconstructive culture was a useful tool to investigate the interaction between periodontal pockets and perioidontopathic bacteria. In inflamed tissues, the expression level of claudin-10 was much increased than in normal tissues. Though the mechanism of this phenomenon is unclear, this data suggested that claudin-10 played important role in developing periodontal tissue destruction.
为了探讨牙周病原菌引起牙周组织破坏的机制,我们建立了PIPAAm三维共培养体系。将牙龈上皮细胞接种于东京CellSeed的Rep Cell板上,培养至融合。然后,将上皮细胞在32℃条件下孵育30min。孵育后,取上皮细胞作为细胞膜。然后将上皮细胞片放置在以1型胶原培养的成纤维细胞上。将上皮细胞和成纤维细胞共培养一周后,我们得到了模拟牙周袋的三维牙龈重建培养物。我们比较了三维牙龈重建培养和正常牙周组织中紧密连接和粘连连接成分claudin、cadherin、JAM-1的表达情况。克拉丁、钙粘附素和JAM-1在三维牙龈重建培养中的表达模式与正常牙周组织中相同。在人牙周袋中,Claudins-1、4、7、12呈结构性表达。此外,在三维牙龈重建培养中也检测到了这些克拉丁。这一数据表明,我们的三维牙龈重建培养是一种有用的工具,可以研究牙周袋和牙周病细菌之间的相互作用。在炎症组织中,claudin-10的表达水平明显高于正常组织。虽然这种现象的机制尚不清楚,但这一数据表明,claudin-10在牙周组织破坏的发生中发挥了重要作用。
