The process whereby a relatively unspecialized cell acquires specialized features of a neuromast hair cell. Hair cells are the sensory receptors of the neuromast and are located in a portion of the neuromast called the sensory strip. Each hair cell of the neuromast is morphologically polarized as a result of the relative position of the single kinocilium and the clusters of stereocilia on its apical surface. There are approximately seven hair cells within each neuromast, with each hair cell innervated by afferent and efferent neurons. The process whereby a relatively unspecialized cell acquires specialized features of a mechanoreceptor, a cell specialized to transduce mechanical stimuli and relay that information centrally in the nervous system. The regrowth of lost or destroyed mechanosensory epithelia. The regrowth of a neuromast following its loss or destruction. The process whose specific outcome is the progression of the neuromast over time, from its formation to the mature structure. The neuromast is the sensory organ of the lateral line and is composed of a population of sensory hair cells, and nonsensory supporting cells and mantle cells. Neuromasts are located superficially on the epithelium or in lateral line canals. Differentiation of new mechanoreceptors to replace those lost or destroyed by injury. Differentiation of new neuromast sensory hair cells to replace those lost or destroyed by injury.
