摘要
目的 :观察麝香多肽体外定向诱导成年大鼠和人骨髓间质干细胞 (Bonemarrowmesenchymalstemcells,BMMSCs)分化为神经元的能力。方法 :采用含 10 0 - 15 0mg/L麝香多肽的无血清L -DMEM培养基诱导成年大鼠和人BMMSCs分化为神经元 ,免疫组化鉴定神经元烯醇化酶 (NSE)、神经丝蛋白 (NF)、胶质纤维酸性蛋白 (GFAP)、神经巢蛋白 (nestin)的表达。结果 :成年大鼠和人BMMSCs在加入含麝香多肽的无血清L -DMEM培养基诱导后 ,BMMSC胞体收缩 ,突起伸出 ,形似神经元 ;免疫组化显示诱导出的神经元样细胞NSE、NF、nestin表达阳性 ,GFAP阴性。结论 :麝香多肽可以在体外诱导成年大鼠和人BMMSCs定向分化为神经元。
AIM: To investigate the differentiation from adult rat and human bone marrow mesenchymal stem cells (BMMSCs) into neuron with musk polypeptide (Mu-P).METHODS: Adult rat and human BMMSCs were induced with Mu-P.Neuron-specific enolase (NSE),neurofilament (NF),Nestin,glial fibrillary acidic protein (GFAP) were detected by immunohistochemistry.RESULTS: Simple methods with Mu-P induced adult rat and human BMMSCs exhibiting a neuronal phenotype,expressing Nestin at 3 hours to 5 hours,and expressing NE and NF at 5 hours to 7 days.But the neuron-like cells didn't express the glial astrocyte marker GFAP.CONCLUSION: Adult rat and human BMMSCs can be induced to differentiate into neurons with Mu-P.
