摘要: 骨形态发生蛋白-2(bone morphogenetic protein-2,BMP-2)属于转化因子,是一种多功能生长因子,在细胞增殖、分化迁移和重建方面具有重要作用。在临床骨缺损修复中,BMP-2是参与体内骨修复至关重要的促进因子。一方面,由于BMP-2在体内的稳定性不强;另一方面,如果无载体保护,其在移植处的释放扩散形式呈“爆炸式”。而骨生长分化是一个动态的过程,因此需要建立一个可控的缓释载体。介绍了目前已应用的4种BMP-2 控制释放载体,包括水凝胶和微囊、层层自组装(layer-by-layer self-assembly,LbL)、表面微处理的钛金属以及静电纺丝纤维。

关键词: 骨形态发生蛋白-2, 控制释放, 骨修复

Abstract: Bone morphogenetic protein-2(BMP-2)is a transforming factor and is a multifunctional growth factor,which plays an important role in cell proliferation,differentiation,migration and reconstruction. BMP- 2 is an important stimulative factor of bone repairing in the clinic application. However,BMP-2 is unstable in vivo,and one common problem is the burst release at very early stages without the protection of a carrier. The growth and differentiation of bone are dynamic processes. Therefore,a controllable release carrier is needed to prevent the burst release. In this paper,we described four controllable release carriers of BMP-2,including hydrogel and microcapsule,layer-bylayer self-assembly(LbL),surface micro processing of titanium and electrospinning.

Key words: bone morphogenetic protein-2(BMP-2), controllable release, bone repairing
