Origin of inner ear hair cells: morphological and functional differentiation from ciliary cells into hair cells in zebrafish inner ear.
Auditory and vestibular functions in vertebrates depend on the transduction of sound vibration or head acceleration into electrical responses in inner ear hair cells. Mechanoelectrical transduction occurs at the tip of stereocilia, which are polarized to form an orientational arrangement that determines directional sensitivity. It remains to be clarified when and how premature hair cells acquir...
متن کاملHair-bundle proteomes of avian and mammalian inner-ear utricles
Examination of multiple proteomics datasets within or between species increases the reliability of protein identification. We report here proteomes of inner-ear hair bundles from three species (chick, mouse, and rat), which were collected on LTQ or LTQ Velos ion-trap mass spectrometers; the constituent proteins were quantified using MS2 intensities, which are the summed intensities of all pepti...
متن کاملTranscription factors in the development of inner ear hair cells.
Inner ear hair cells are the sensory receptors that detect and convert sound vibrations and head movements into neural signals. However, in humans, these cells are unable to regenerate if they are damaged or lost. Over thepast decade,there has been an exponential increase in interest and progress in understanding of the development of the inner ear and of hair cells, aiming to gain insights int...
متن کاملCell biology of mechanotransduction in inner-ear hair cells
The cloning of deafness genes, especially those for Usher syndrome, has helped to identify a variety of structural proteins involved in the development and function of hair-cell stereocilia. These include novel cadherins, a handful of myosin motors, and scaffolding proteins. Yet a new understanding of these proteins has upended the orthodox view of mechanosensation by hair cells.
متن کاملNotch signaling is required for the generation of hair cells and supporting cells in the mammalian inner ear.
Sensorineural deafness and balance dysfunction are common impairments in humans frequently caused by defects in the sensory epithelium of the inner ear, composed of hair cells and supporting cells. Lineage studies have shown that hair cells and supporting cells arise from a common progenitor, but how these progenitors are generated remains unknown. Although various molecules have been implicate...
