摘要 目的:探讨大鼠脊髓挤压伤后硫酸软骨素蛋白多糖(CSPGs)在时间和空间的变化。方法:①采用大鼠脊髓挤压伤模型,实验动物随机分为脊髓压迫后0h、8h、24h、48h、72h、1周、2周组。对不同时间点的脊髓标本进行HE染色;计算脊髓损伤区的实际面积;②探讨脊髓挤压伤后CSPGs在时间和空间分布的变化,并观察CS-56在损伤后的表达及其和GFAP的关系。结果:CSPGs在脊髓损伤后表现出强大的抑制作用,免疫荧光染色结果显示,CS-56表达于24h内开始升高,3d后CS-56呈环状分布于损伤区周围,GFAP有少量表达,1周时空洞逐渐出现,2周时空洞轮廓明显,CS-56充填于空洞腔内。结论:分析硫酸软骨素蛋白多糖NG2在时间和空间分布的变化有助于确定抑制其分泌的时间窗,为细胞移植治疗脊髓损伤提供一定的内环境支持。
