摘要:

文题释义:
引导性组织/骨再生术:是指将屏障膜置于软组织与骨缺损之间,阻止干扰骨形成且迁移速度较快的结缔组织细胞和上皮细胞进入骨缺损区,并提供一定的空间,引导具有附着能力的牙周膜细胞和具有骨再生能力的前体成骨细胞优先进入骨缺损区,从而达到牙周组织/骨组织再生的目的。
Ⅰ型胶原蛋白:胶原蛋白是动物和人体大多数软硬组织中最主要的结构蛋白,具有良好的生物相容性、低免疫原性和组织可降解吸收性。Ⅰ型胶原蛋白是动物界含量最丰富的蛋白质之一,是人体内含量最丰富的基质蛋白,其构成大部分组织的细胞外基质,为细胞生长、增殖提供微环境和附着表面,是理想的医用生物材料。

背景:近年来鱼类来源胶原蛋白被视为哺乳动物胶原蛋白的潜在替代品,其在生物医学材料领域的研究逐渐成为热点,保留鱼鳞外形所得鱼鳞胶原材料具有优良的机械性能,目前尚无研究探索此类材料是否有骨组织再生的潜力。
目的:探讨鱼鳞胶原膜对大鼠骨髓间充质干细胞黏附增殖及成骨分化的作用。
方法:通过草鱼鱼鳞制备胶原膜,大体及扫描电镜观察鱼鳞胶原膜结构,傅里叶变换红外光谱分析鉴定胶原蛋白类型,差示扫描量热仪测定鱼鳞胶原膜变性温度;取第3代大鼠骨髓间充质干细胞,接种于胶原膜上培养为实验组,常规细胞贴壁培养为对照组。扫描电镜观察鱼鳞胶原膜上细胞黏附情况;CCK-8实验检测各组细胞增殖活性;碱性磷酸酶染色检测各组细胞成骨分化能力。
结果与结论:①鱼鳞胶原膜为方圆形,透光性较高,表面可见“年轮状”纹路,扫描电镜观察可见鱼鳞胶原膜为多板层状结构,由I型胶原和羟基磷灰石构成,变性温度测定结果为50.55 ℃;②鱼鳞胶原膜表面骨髓间充质干细胞黏附良好,细胞增殖优于对照组,鱼鳞胶原膜表面细胞碱性磷酸酶活性高于对照组,差异均有显著性意义;③结果表明,鱼鳞胶原膜表面骨髓间充质干细胞黏附良好,可促进骨髓间充质干细胞增殖及成骨向分化,具有良好的生物相容性及骨组织再生潜力。

Abstract: BACKGROUND: In recent years, fish derived collagen has been regarded as a potential substitute for mammalian collagen, and its research in biomedical materials has gradually become a hot spot. Fish scale collagen materials with preserved fish scale shape have excellent mechanical properties, and there is no research to explore whether this material has the potential of bone tissue regeneration.
OBJECTIVE: To study the effect of fish scale collagen membrane on the adhesion, proliferation and osteogenic differentiation of rat bone marrow mesenchymal stem cells. 
METHODS: The collagen membrane was prepared from Ctenopharyngodon idellus scales. The structure of collagen membrane was observed by naked eye and scanning electron microscope. The type of collagen was identified by Fourier transform infrared spectroscopy. The denaturation temperature of collagen membrane was determined by differential scanning calorimetry. Rat bone marrow mesenchymal stem cells at passage 3 were cultured in vitro on collagen membrane as experimental group; and those received conventional cell adherent culture were used as control group. The adhesion of cells on the collagen membrane of fish scale was observed by scanning electron microscope. The proliferation activity of cells in each group was detected by CCK-8, and the osteogenic differentiation ability of cells in each group was detected by alkaline phosphatase staining. 
RESULTS AND CONCLUSION: (1) The fish scale collagen membrane was square and round, the light transmittance was high, and the “annual ring” pattern could be seen on the surface. Scanning electron microscope showed that the fish scale collagen membrane was multi-lamellar structure, which was composed of type I collagen and hydroxyapatite, and the denaturation temperature was 50.55 ℃. (2) The adhesion of bone marrow mesenchymal stem cells on the surface of fish scale collagen membrane was good, and the cell proliferation was better than that of the control group. The alkaline phosphatase activity of the surface cells of fish scale collagen membrane was higher than that of the control group, and the difference was statistically significant. (3) Results suggested that bone marrow mesenchymal stem cells on the surface of fish scale collagen membrane have good adhesion, which can promote cell proliferation and osteoblast differentiation, and has good biocompatibility and the potential of bone tissue regeneration.
