Failures in neurulation lead to severe anomalies of the nervous system, called neural tube defects (NTDs), which are among the most common congenital malformations in humans. Mechanisms causing NTDs in humans remain ill-defined. Of particular interest, the thoracolumbar region, which encompasses many NTD cases in the spine, corresponds to the junction between primary and secondary neurulations. Elucidating which developmental processes operate during neurulation in this region is therefore pivotal to unraveling the etiology of NTDs. Here, using the chick embryo as a model, we show that, at the junction, the neural tube is elaborated by a unique developmental program involving concerted movements of elevation and folding combined with local cell ingression and accretion. This process ensures the topological continuity between the primary and secondary neural tubes while supplying all neural progenitors of both the junctional and secondary neural tubes. Because it is distinct from the other neurulation events, we term this phenomenon junctional neurulation. Moreover, the planar-cell-polarity member,<jats:italic>Prickle-1<\/jats:italic>, is recruited specifically during junctional neurulation and its misexpression within a limited time period suffices to cause anomalies that phenocopy lower spine NTDs in human. Our study thus provides a molecular and cellular basis for understanding the causality of NTD prevalence in humans and ascribes to<jats:italic>Prickle-1<\/jats:italic>a critical role in lower spinal cord formation.<\/jats:p>","DOI":"10.1523\/jneurosci.1850-14.2014","type":"journal-article","created":{"date-parts":[[2014,9,24]],"date-time":"2014-09-24T16:58:27Z","timestamp":1411577907000},"page":"13208-13221","source":"Crossref","is-referenced-by-count":94,"title":["Junctional
