摘要:

背景:牙周组织工程技术为修复牙周炎骨组织缺损提供新思路和新方法。
目的:体外培养小型猪牙周膜干细胞,并与羟基磷灰石进行骨组织构建,研究其与羟基磷灰石支架材料的生物相容性。
方法:采用组织块法获得小型猪牙周膜干细胞,用免疫荧光法检测细胞中基质细胞抗原1的表达。取第3代小型猪牙周膜干细胞接种在羟基磷灰石支架材料上复合培养,分别在培养第1,3,7天用扫描电镜观察细胞在羟基磷灰石上的生长情况。
结果与结论:原代培养的小型猪牙周膜干细胞生长良好,细胞中基质细胞抗原1免疫荧光呈阳性。扫描电镜结果表明,培养第1,3,7天,牙周膜干细胞在羟基磷灰石上生长良好。证实,实验采用组织块法成功体外分离培养了小型猪牙周膜干细胞,可在羟基磷灰石支架材料上良好的生长。

Abstract:

BACKGROUND: Periodontal tissue engineering technology provides new ideas and new ways for periodontitis-induced bone defect repair.
OBJECTIVE: To develop a culture model for the periodontal ligament cells of miniature swine, which was constructed with hydroxyapatite, to investigate the biocompatibility with hydroxyapatite.
METHODS: Periodontal ligament cells from miniature swine were harvested by using tissue explant method. Immunofluorescence was used to detect the expression of stromal cell antigen 1 in the periodontal ligament cells of miniature swine. The third passage cells were co-cultured with a three-dimension hydroxyapatite scaffold, and the biological characteristics of the cells were observed under a scanning electron microscope at days 1, 3, 7 of co-culture.
RESULTS AND CONCLUSION: The pirmary miniature swine periodontal ligament cells grew well, and they were positive for stromal cell antigen 1. Under the scanning electron microscope, the periodontal ligament cells of miniature swine grew well on the hydroxyapatite scaffold at days 1, 3, 7 of co-culture. These prove that the miniature swine periodontal ligament cells, which can be separated using tissue explant method and cultured successfully in vitro, can grow well on the hydroxyapatite scaffold.
