| Research Abstract |
We showed that the lateral line mechanosensory receptors, neuromasts, migrate across the epidermal cell layer, which resembles migration of the motor neurons across the neuroepithelial cell layer (Wada et al., 2008). By taking advantage of easy accessibility of the lateral line system, we revealed that the nueromast gives rise to new neuromast by a budding process. We also showed that the difference in morphogenesis of the underlying dermal bones would be sufficient to account for the corresponding difference in the lateral line pattern (Wada et al., 2010). These results suggest that the interaction between the neuromast cells and epidermal cells is important for pattern formation of the lateral line system.
