摘要
目的检测神经组织细胞特异性抗原及神经营养因子 3 (NT 3 )、乙酰胆碱转移酶 (ChAT)在大鼠羊膜上皮细胞中的表达。方法从孕 12— 14d的Wistar大鼠羊膜中分离羊膜上皮细胞 ,通过免疫细胞化学检测神经组织细胞特异性抗原 (MAP 2、NSE、GFAP、Nestin、Musashi)及ChAT、NT 3在羊膜上皮细胞中的表达。结果羊膜上皮细胞表达神经干细胞、神经细胞、神经胶质细胞特异性抗原 ,并且在羊膜上皮细胞中有ChAT与NT 3的表达。结论羊膜上皮细胞与神经组织细胞具有一定的同源性 ;羊膜可望作为治疗神经系统疾病新的细胞来源。
ObjectiveTo detect specific antigens of neural cells in amniotic epithelial cells(AECs) in rats. MethodsAECs were dissociated and purified from the amnion of pregnancy 12—14 d rats. The expression of specific markers of neural stem cells (Nestin, Musashi) and differentiated cells (MAP-2, NSE, GFAP) and ChAT, NT-3 in the AECs were detected by immunocytochemistry. ResultsThe cultured AECs displayed positive immunoreactivity to MAP-2, NSE, GFAP, Nestin and Musashi. In addition, the cells also demonstrated immunoreactivity to ChAT and NT-3. ConclusionAECs are similar with neural cells and it may be useful as a sustained source to improve outcome of neural stem cells transplantation.
