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 کاملGene Expression by Mouse Inner Ear Hair Cells during Development.
Hair cells of the inner ear are essential for hearing and balance. As a consequence, pathogenic variants in genes specifically expressed in hair cells often cause hereditary deafness. Hair cells are few in number and not easily isolated from the adjacent supporting cells, so the biochemistry and molecular biology of hair cells can be difficult to study. To study gene expression in hair cells, w...
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 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 کاملHair cells and supporting cells share a common progenitor in the avian inner ear.
Sensory organs of the vertebrate inner ear contain two major cell types: hair cells (HCs) and supporting cells (SCs). To study the lineage relationships between these two populations, replication-defective retroviral vectors encoding marker genes were delivered to the otic vesicle of the chicken embryo. The resulting labeled clones were analyzed in the hearing organ of the chicken, called the b...
