Abstract
Work on zebrafish mutants that develop supernumerary neuromasts in the lateral line has revealed an inhibitory mechanism, mediated by glial cells, that represses newly identified precursors of secondary neuromasts, ensuring successive waves of neuromast production occur on time. The alignment of hair cells in neuromasts corresponds to the timing of these waves.
