摘要:
目的    探讨同种异体脱细胞脊髓支架的制备方法并分析其可能含有的有效成分。    方法    采用冻融+化学萃取方法制备脱细胞脊髓支架,光镜及扫描电镜观察其结构特征;用免疫组织化学法分析脱细胞支架的主要成分。    结果    正常的大鼠脊髓组织经脱细胞处理后,清除了所有的细胞成分及髓鞘和轴突,扫描电镜显示保存了细胞外基质成分构成了三维支架结构。成分分析结果显示,存留的支架结构中含有层黏连蛋白(laminin, LN)、纤连蛋白(fibronectin, FN)、Ⅳ型胶原等诱导和促进神经再生、促进细胞黏附和增殖的重要成分。    结论    脱细胞异体脊髓具有三维支架结构,含有诱导和促进神经再生的相关蛋白,有利于受损神经的再生及移植细胞的存活和增殖。
Abstract:
Objective    To prepare the acellular scaffold of spinal cord and analyze its component.     Methods    The acellular scaffold was prepared with the freeze thawing and chemical extraction, its structure was observed by HE and SEM, its component was analyzed by immunohistochemistry.     Results    The cells, myelin sheath and axon of nerve fibers in the rat spinal cord were eliminated, but three-dimensional supports of extracellular matrix were reserved. The analytical results showed the component of the acellular spinal cord contain laminin, fibronectin and type Ⅳ collagen—the necessary components to facilitate and induce the regeneration of the injured nerves and enhance the adhesion and proliferation of cells.     Conclusion    The acellular spinal cord has three dimensional structure and contains several proteins related to the regeneration of the injured nerves and promotion of  the survival and proliferation of cells.
