Zusammenfassung:	The invention relates to the field of biotechnology, in particular to an inducing method for differentiating umbilical cord mesenchymal stem cells into nerve cells, which comprises the following steps of: cultivating the separated umbilical cord mesenchymal stem cells in an MSC culture medium to spread a whole culture dish; cultivating the stably-subculturing mesenchymal stem cells in the culture dish which is spread with the extracellular matrix by means of the MSC culture medium to be 70% confluence; and leading the 70% confluent mesenchymal stem cells to sequentially pass through four inducing culture mediums to cultivate, wherein the four inducing culture mediums comprise the following factors of 5-azacytidine+Pam3CSK4, bFGF+Noggin, bFGF+RA+FGF8+Wnt3a, and Bmp4+Shh+RA+NGF+BDNF. The inducing method has the benefit effects of being free of chemical substances with cytotoxicity, transgenic technology and nerve cell co-cultivation, and being high in differentiating efficiency and shorter in time consumption.
