随着世界人口老龄化和欧洲约20%的成年人受到骨骼疾病的影响,迫切需要开发先进的再生方法和生物材料,既能促进组织再生,又能提供足够的微环境使细胞茁壮成长。由于骨的主要成分是胶原蛋白和磷灰石矿物,组织工程领域的科学家们试图通过使用不同的仿生方法将这些材料结合起来以促进骨修复。尽管如此,一种能够模拟松质骨的不同特性(即机械特性、降解率、孔隙率等)的理想骨模拟物仍有待开发。这篇综述旨在总结目前对骨组织矿化和结构的理解,同时对骨组织工程应用中现有的矿化胶原仿生策略提供了关键的展望,突出了知识存在的差距。
With an ageing world population and ~20% of adults in Europe being affected by bone diseases, there is an urgent need to develop advanced regenerative approaches and biomaterials capable to facilitate tissue regeneration while providing an adequate microenvironment for cells to thrive. As the main components of bone are collagen and apatite mineral, scientists in the tissue engineering field have attempted in combining these materials by using different biomimetic approaches to favour bone repair. Still, an ideal bone analogue capable of mimicking the distinct properties (i.e., mechanical properties, degradation rate, porosity, etc.) of cancellous bone is to be developed. This review seeks to sum up the current understanding of bone tissue mineralisation and structure while providing a critical outlook on the existing biomimetic strategies of mineralising collagen for bone tissue engineering applications, highlighting where gaps in knowledge exist.
