摘要:

背景:异种生物衍生骨保存了原骨组织的天然网状孔隙结构,且具有免疫原性低、细胞相容性好的特点。

目的:验证异种生物衍生骨材料与骨髓间充质干细胞的生物相容性。
方法:取新鲜猪股骨制备生物衍生骨,扫描电镜观察材料结构。将第3代兔骨髓间充质干细胞以2×109 L-1的浓度接种于生物衍生骨材料的松质骨面,复合培养7 d内,采用扫描电镜观察细胞生长情况;复合培养8 d内,计数材料上附着的细胞数。
结果与结论:生物衍生骨表面粗糙,孔隙不规则并相互通联,构成网状结构。复合培养3 d,细胞在衍生骨材料表面发生附着,且细胞形态不均一;复合培养培养 5 d,细胞连接成片呈层状生长,细胞之间紧密接触;复合培养7 d,细胞呈现多层生长状态,成堆生长,部分区域存在细胞外基质分泌现象。复合培养后,前2 d 为潜伏适应期,3-6 d细胞生长呈出线性曲线,处于细胞生长对数期;第 6 天后,细胞生长曲线逐渐变得平缓,细胞增殖速度下降,增殖进入平台期。表明异种生物衍生骨材料与骨髓间充质干细胞具有良好的生物相容性。

Abstract:

BACKGROUND: Bio-derived xenograft bone has natural pore structure of the bone, low immunogenicity, and good cytocompatibility.

OBJECTIVE: To verify the biocompatibility of bio-derived xenograft bone with bone marrow mesenchymal stem cells.
METHODS: Fresh pig femoral bone was collected to prepare bio-derived bone. Scanning electron microscope was used to observe the material structure. Passage 3 rabbit bone marrow mesenchymal stem cells at a density of 2×109/L were inoculated into the cancellous bone surface of the bio-dervied bone and cultured for 7 days. Cell growth was detected using scanning electron microscope. After culture for 8 days, cell number was counted.

RESULTS AND CONCLUSION: The bio-derived bone had rough surface and irregularly interconnected pores constructing a mesh-like structure. After 3 days of compound culture, cells had irregular shapes and adhered to the surface of bio-derived bone; after 5 days of culture, cells were closely interconnected to form a layered growth; after 7 days of culture, cells exhibited multilayered growth and the extracellular matrix secreted locally. Under compound culture, the former 2 days were latent period, 3-6 days were logarithmic phase, and from the 6th day, the cell growth curve became smooth gradually and the cell proliferation decreased and entered into the plateau period. These findings indicate that the bio-derived xenograft bone has good biocompatibility with bone marrow mesenchymal stem cells.
