文题释义:
胶原-生物活性玻璃-聚己内酯复合支架材料:胶原是最常用的天然生物材料,是骨组织和牙本质的天然成分,生物相容性良好,但机械性能差且易收缩,不利于牙髓细胞生长;生物活性玻璃作为一种人工合成材料,其骨诱导性能良好,与胶原共同组成的胶原-生物活性玻璃材料可促进牙本质的形成和修复;但胶原-生物活性玻璃复合材料的缺点是机械性能差,不利于牙髓细胞的迁移、增殖和分化;综合胶原、生物活性玻璃和聚己内酯合成的复合材料胶原-生物活性玻璃-聚己内酯可兼具良好的生物相容性和机械性能。
牙髓细胞:是牙髓中的主要细胞,呈星形,有胞质突起互相连接,核染色深,胞质淡染,均匀,主要功能是可增生,分化新的成纤维细胞或牙本质细胞。
 
 
背景:胶原-生物活性玻璃-聚己内酯复合材料具有良好的生物相容性、机械性能及可降解性,对细胞的黏附、增殖及血管生成极为有利。
目的:观察胶原-生物活性玻璃-聚己内酯复合支架材料对人牙髓细胞的增殖、迁移和分化能力的影响。
方法:分离培养人牙髓细胞,接种在胶原-生物活性玻璃-聚己内酯支架材料上,接种前及接种后第1,3,7,14,24天,采用MTT法检测细胞增殖,采用划痕实验检测细胞的迁移能力,采用ELISA法检测细胞上清液中的碱性磷酸酶活性。

结果与结论:①与接种前比较,接种于胶原-生物活性玻璃-聚己内酯支架材料上的细胞增殖能力明显增强(P < 0.01);随着接种时间的延长,胶原-生物活性玻璃-聚己内酯支架材料上的细胞增殖能力逐渐增强;②与接种前比较,接种于胶原-生物活性玻璃-聚己内酯支架材料上的细胞迁移能力明显增强(P < 0.01);随着接种时间的延长,胶原-生物活性玻璃-聚己内酯支架材料上的细胞迁移能力逐渐增强;③与接种前比较,接种于胶原-生物活性玻璃-聚己内酯支架材料上的细胞上清液中碱性磷酸酶水平明显增加(P < 0.01);随着接种时间的延长,胶原-生物活性玻璃-聚己内酯支架材料上的细胞上清液中碱性磷酸酶水平逐渐增强;④结果表明,胶原-生物活性玻璃-聚己内酯复合支架材料可促进人牙髓细胞的增殖、迁移和分化过程。

Abstract:

BACKGROUND: Collagen-bioglass-polycaprolacton (COL-BG-PCL) composites have good biocompatibility, mechanical properties and biodegradability that are beneficial to cell adhesion, proliferation and angiogenesis.

OBJECTIVE: To study the effect of COL-BG-PCL bioactive scaffold on the proliferation, migration and differentiation of human dental pulp cells (hDPCs).
METHODS: hDPCs were isolated and cultured on the COL-BG-PCL bioactive scaffold. MTT, cell scratch test and enzyme-linked immunosorbent assay (ELISA) assay were used to detect the proliferation, migration and differentiation abilities of hDPCs before and at 1, 3, 7, 14, 24 days after inoculation onto the COL-BG-PCL bioactive scaffold.
RESULTS AND CONCLUSION: Compared with the cells without inoculation onto the COL-BG-PCL bioactive scaffold, (1) the proliferation ability of the cells cultured on the COL-BG-PCL scaffold was significantly enhanced (P < 0.01), and with the prolongation of the inoculation time, the cell proliferation ability was gradually increased; (2) the cell migration ability of the cells cultured on the COL-BG-PCL scaffold was significantly enhanced (P < 0.01), and with the prolongation of the inoculation time, the migration ability of the cells cultured on the COL-BG-PCL scaffold was gradually increased; (3) the level of alkaline phosphatase in the supernatant of the cells cultured on the COL-BG-PCL scaffold was significantly increased (P < 0.01), and with the prolongation of the inoculation time, the level of alkaline phosphatase in the supernatant was gradually increased. In summary, the COL-BG-PCL scaffold can promote the proliferation, migration and differentiation of hDPCs.
