Mouse node cilia are posteriorly tilted to generate a leftward fluid flow and left/right asymmetry in the embryo, but how the tilt comes about was not known. The basal bodies of node cilia gradually shift from a central position towards the posterior side of node cells in a dishevelled and non-canonical Wnt signalling-dependent manner and follow a shift in Dvl localization to the posterior.
