Cell adhesion is one of the most important properties controlling embryonic development. Extremely precise cell-cell contacts are established according to the nature of adhesion molecules that are expressed on the cell surface. The identifica- tion of several families of adhesion molecules, well conserved throughout evolu- tion, has been the basis of a considerable amount of work over the past 20 years that contributed to establish functions of cell adhesion in almost all organs. Nowadays, cell adhesion molecules are not just considered as cellular glue but are thought to play critical roles...

The complexarchitectureofneuronal networks togetherwith the extraordinary associated functions make the nervous system a fascinating biological structure. The considerable work performed to explore this cellular machinery is nowadays successfulbecause the mysteryofnervous system developmentisbeing unravelled. As described in their outstanding review published 10 years ago in Science.' Marc Tessier-Lavigne and Corey Goodman-the pioneers of the molecular era of axon guidance-summarized the assembly of nervous system connections as a subtle game of attraction and repulsion of neuronal growth...
