Development of synthetic biomaterials imbued with inorganic and organic characteristics of natural bone that are capable of promoting effective bone tissue regeneration is an ongoing goal of regenerative medicine. Calcium phosphate (CaP) has been predominantly utilized to mimic the inorganic components of bone, such as calcium hydroxyapatite, due to its intrinsic bioactivity and osteoconductivity. CaP-based materials can be further engineered to promote osteoinductivity through the incorporation of osteogenic biomolecules. In this study, we briefly describe the microstructure and the process of natural bone mineralization and introduce various methods for coating CaP onto biomaterial surfaces. In particular, we summarize the advantages and current progress of biomimetic surface-mineralizing processes using simulated body fluids for coating bone-like carbonated apatite onto various material surfaces such as metals, ceramics, and polymers. The osteoinductive effects of integrating biomolecules such as proteins, growth factors, and genes into the mineral coatings are also discussed.
开发具有天然骨的无机和有机特性的合成生物材料,以促进有效的骨组织再生,是再生医学的一个持续目标。磷酸钙 (CaP) 由于其内在的生物活性和骨引导性,主要被用于模拟骨的无机成分,如钙羟磷灰石。通过掺入成骨生物分子,CaP 基材料可以进一步设计以促进成骨诱导性。在本研究中,我们简要描述了天然骨矿化的微观结构和过程,并介绍了在生物材料表面涂覆 CaP 的各种方法。特别是,我们总结了使用模拟体液进行仿生表面矿化处理的优点和最新进展,以将类似骨的碳酸磷灰石涂覆在各种材料表面,如金属、陶瓷和聚合物。我们还讨论了将蛋白质、生长因子和基因等生物分子整合到矿物涂层中的成骨诱导作用。
