BDNF has critical function in promoting survival and growth of neurons, but its downstream regulation mechanism is still not fully understood.In order to explore whether BDNF can play a role by Wnt/3-catenin pathway in human embryonic spinal cord neurons, we successfully cultured hESC-NC and found the number and cell viability were increased after transfected by plRES2-ZsGreen l-BDNF plasmid.Expression of Wnt, Frizzled, Dsh were up-regulated in by Real-time PCR and Western blot, particularly GSK-3β down-regulated.
