骨组织工程支架研究现状及面临的问题

在理想骨组织工程支架所需满足条件的基础上，从材料的选取、设计、制备等方面就其发展现状做出了简要总结。国内外大量的实验证实了骨组织工程支架缺损修复的可行性、有效性及优越性。然而，目前构建的骨组织工程支架还很不完善，在力学性能、降解速度、结构形态、生物活性等方面仍有许多问题亟待解决。随着骨组织工程及其相关领域研究的深入和进步，骨组织工程支架的研究将会具有突破性的进展。

Research process and problem of bone tissue engineering scaffold

Based on the requirements of ideal bone tissue engineering scaffold need to meet, this paper briefly summarized bone tissue engineering scaffold from material selection, design and preparation. Many domestic and abroad experiments have confirmed that bone tissue engineering scaffold is feasible, effective and superior in repairing bone tissue defects. However, so far, the constructed bone tissue engineering scaffold is far from perfect, some areas, such as the mechanical properties, degradation of speed, structure and biological activity, are still need to be resolved. With further carrying out, the research of bone tissue engineering scaffold will have ground-breaking progress, and it will have a bright future in the clinical applications.
