Neural tube defects are a common neurodevelopmental disease,which can be divided into open and closed types.The main symptoms are anencephaly,encephalocele and cranial spina bifida.The relationship between Wnt signaling and neurogenesis has been a popular area in recent years.The Wnt signaling pathway includes Wnt/β-catenin,planar polar cell pathway and Wnt/Ca2+pathway,which plays an important role in neural tube development.This article reviews the current state of research on the Wnt signaling pathway and elucidates the role it plays in the process of neural tube closure,providing insights for the development of drugs related to the prevention and treatment of neural tube defects.
