... of EcRB1. Wnt5 JNK Ecdysone Dendrite pruning Drosophila Sensory neurons During the development of the nervous system, neurons often form exuberant axon branches and dendritic arbors and then selectively prune those that make incorrect connections. One major form of developmental...

... urchin, a prototypic deuterostome, the ectoderm-endoderm boundary is established before gastrulation, and ectodermal cells at the boundary are thought to provide patterning inputs to the underlying mesenchyme. Here we show that a short-range Wnt5 signal from the endoderm actively patterns the adjacent...

...,such as dishevelled or Tcf , also results in ventrally curved salivary glands. Analysis of a second Wnt signal, which acts through the atypical Wnt receptor Derailed, indicates a requirement for Wnt5 signaling late in salivary gland migration. WNT5 is expressed in the central nervous system and acts as a repulsive...
