摘要:

背景:胰岛素样生长因子1具有促进成纤维细胞有丝分裂的作用,同时具有促进牙周细胞生长、分化及合成细胞外基质的作用。
目的:观察负载胰岛素样生长因子1的壳聚糖胶原支架对于人牙周膜细胞增殖的作用。
方法:将人牙周膜细胞分别接种于负载胰岛素样生长因子1的壳聚糖胶原支架与普通胶原支架上,于接种的1 h、24 h及1周检测重组人转化生长因子β1的释放,于第1,7,28天检测两组细胞的黏附和增殖情况。
结果与结论:负载胰岛素样生长因子1的壳聚糖胶原支架组第1,24小时和第1周的重组人转化生长因子β1释放率明显低于普通胶原支架组(P < 0.01)。两组接种第1天的细胞黏附和增殖检测比较差异无显著性意义  (P > 0.05),负载胰岛素样生长因子1的壳聚糖胶原支架组接种第7,28天的细胞黏附和增殖情况优于普通胶原支架组(P < 0.01)。表明负载胰岛素样生长因子1的壳聚糖胶原支架可显著促进人牙周膜细胞的增殖。

Abstract:

BACKGROUND: Insulin-like growth factor-1 can promote mitosis of fibroblasts as well as periodontal cell growth, differentiation and synthesis of extracellular matrix.
OBJECTIVE: To observe the effects of chitosan/collagen composite scaffold carrying insulin-like growth factor-1 on proliferation of human periodontal ligament cells.
METHODS: The human periodontal ligament cells were seeded on chitosan/collagen composite scaffold carrying insulin-like growth factor-1 and ordinary collagen scaffold. The release of recombinant human transforming growth factor-β1 was detected at 1, 24 hours and 1 week after culture; cell adhesion and proliferation were detected at days 1, 7 and 28.
RESULTS AND CONCLUSION: The release rate of recombinant human transforming growth factor-β1 in the composite scaffold was significantly lower than that in the ordinary collagen scaffold at 1, 24 hours and 1 week after cell seeding (P < 0.01). The cell adhesion and proliferation showed no difference between two groups at day 1 after cell seeding, but became significantly higher in the composite scaffold than that in the ordinary collagen scaffold at days 7 and 28 (P < 0.01). These findings indicate that chitosan/collagen composite scaffold carrying insulin-like growth factor-1 can significantly promote the proliferation of the human periodontal ligament cells.
