英文摘要：

Tissue engineering technology has been applied to prepare nerve conduits for repairing nervous system＇s injury and has become the focus in the field of nervous system＇ s regeneration. Using biological materials in the form of microspheres has become main issues. Microspheres can release bioactive substances in a sustained and controlled manner,they improve the microenvironment of nervous system＇ s regeneration. This paper reviews candidate materials,fabrication techniques,and detection methods for preparing microspheres and discuss the role of microspheres in nervous system＇s injury and repair.
