用胚胎脊髓腹侧组织块植入缺损运动神经元的大鼠脊髓内;同时把带有神经的拇长伸肌移放到脊髓移植物旁.其神经的断端插入移植的部位.应用碱性成纤维细胞生长因子作用脊髓移植物,经HRP逆行追踪、乙酰胆碱酯酶和琥珀酸脱氢酶组化染色等方法显示:碱性成纤维细胞生长因子对移植的胚胎脊髓神经元的存活与生长有促进作用
The embryonic spinal ventral tissue was implanted into the spinal cord of rats with deficient motoneurons. At the same time, the neuromuscular hallucis longus muscle was transplanted to the spinal cord graft with its broken ends inserted into the transplanted area. Fibroblast growth factor role of spinal cord transplantation, HRP retrograde tracing, acetylcholinesterase and succinate dehydrogenase staining and other methods show: basic fibroblast growth factor on the survival and growth of transplanted embryonic spinal cord neurons have enhancement
