摘要
目的 探讨神经营养因子诱导成年大鼠骨髓基质细胞成神经细胞的可能性,为神经再生及视神经疾病的治疗提供一种新方法。方法 从大鼠骨髓中分离培养骨髓基质细胞并传至第6代,诱导前24h光用含1μg/L bFGF及 20%FBS的DMEM培养液培养,以促迸细胞分裂,然后用神经生长因子(NGF)和脑源性神经生长因子(BDNF)作诱导剂,观察细胞形态的变化,并采用免疫组织化学法检测诱导后的细胞表达Nestin、NF、NSE、Map-2、GFAP等特异性标志物。结果 诱导后1h,部分细胞的形态已发生改变,5h后大部分细胞不仅在形态上表现为神经元样特征,而且Nestin、NF、NSE及Map-2等特异性抗体呈阳性表达,而GFAP抗体表达呈阴性。结论 神经营养因子能将骨髓基质细胞诱导成神经元样细胞。
