著录项
摘要
一种将硬质材料和细胞一体化打印的技术,一种制备具有骨修复功能的骨生成微环境模块,骨样方法以及应用快速修复骨缺损的方法。进一步提供了一种作为独立骨生成因子的生物微环境因素的制备方法。本集成3D打印技术通过调整温度实现细胞的同步打印和硬质材料,以构建一种真正的生物仿生骨组织,可以根据患者的特定缺陷和临床需求进行定制。在本骨修复功能模块中,细胞在硬质材料表面具有高生存率和增殖活性,实现骨生成和骨吸收的双重代谢功能,促进血管化和神经生成,提高弹性模量和减少应力遮挡。
【原文】A technology of 3D printing integration of hard materials and cells, a preparation of bone-repair functional module with osteogenic microenvironment, bone organoid method and the application of quick repair of bone defects are provided. A preparation method of biological microenvironmental factors as independent osteogenic factors is further provided. The present integrated 3D printing technology realizes 3D printing of cells and hard materials synchronously by adjusting the temperature, so as to build a real sense of biomimetic bone tissue, which can be customized according to the specific defects and clinical needs of patients. In the present bone-repair functional module, the cells have high survival rate and proliferation activity on the surface of hard materials, and realize osteogenic differentiation and mineralization; after implantation, it has the dual metabolic functions of bone formation and bone resorption, promoting vascular and neurogenesis, improving elastic modulus and reducing stress shielding.
