BDNF has critical function in promoting survival,differentiation and proliferation of Neural stem cells, but its downstream regulation mechanism is still not fully understood.In order to explore whether BDNF can play a role by Wnt/β-catenin pathway in human embryonic spinal cord NSCs, we successfully cultured hESC-NSCs and found the number, area and differentiation of NSCs were increased after transfected by pIRES2-ZsGreen1-BDNF plasrnid.
