    Abstract:

    Objective:Porcine naive-like embryonic stem cells were induced to differentiate into neural cells in vitro,which provided basic information for the repair and treatment of the neurological disease. Methods:The neural-inducing culture medium with small molecule compounds β-mercaptoethanol,B-27 and heparin was used to differentiate the porcine naive-like embryonic stem cells towards the neural-like cells. We have derived neural-like cells with identification of the neural specific gene expression. We detected whether these cells could show limited pluripotency. Results:The neural-like cells had obvious neuronal cell structure. RT-PCR and immunofluorescence data showed that the differentiated neurons expressed a variety of neural cell-specific genes. QPCR results showed that the expression of pluripotent factors was decreased significantly after differentiation process and the expression of nerve-specific genes was significantly increased. The results of immunofluorescence showed that the rate of light neurofilament protein(NF-L)positive cells reached 79%. Conclusion:Neural cells could be directly induced from porcine naive-like embryonic stem cells in vitro.
