Molecular mechanisms of inner ear development.
The inner ear is a structurally complex vertebrate organ built to encode sound, motion, and orientation in space. Given its complexity, it is not surprising that inner ear dysfunction is a relatively common consequence of human genetic mutation. Studies in model organisms suggest that many genes currently known to be associated with human hearing impairment are active during embryogenesis. Henc...
متن کاملSensory organ development in the inner ear: molecular and cellular mechanisms.
The molecular mechanisms underlying the specification of sensory organs in the inner ear and the development of hair and supporting cells within these organs are described. The different organs are all derived from a common pro-sensory region, and may be specified by their proximity to the boundaries between compartments - broad domains within the otocyst defined by the asymmetric expression pa...
متن کاملSp8 regulates inner ear development.
A forward genetic screen of N-ethyl-N-nitrosourea mutagenized Xenopus tropicalis has identified an inner ear mutant named eclipse (ecl). Mutants developed enlarged otic vesicles and various defects of otoconia development; they also showed abnormal circular and inverted swimming patterns. Positional cloning identified specificity protein 8 (sp8), which was previously found to regulate limb and ...
متن کاملThe molecular architecture of the inner ear.
The inner ear is structurally complex. A molecular description of its architecture is now emerging from the use of contemporary methods of cell and molecular biology, and from studies of ontogenetic development. With the application of clinical and molecular genetics, it has now become possible to identify genes associated with inherited, non-syndromic deafness and balance dysfunction in humans...
متن کاملThe development of the vertebrate inner ear
The inner ear is a complex sensory organ responsible for balance and sound detection in vertebrates. It originates from a transient embryonic structure, the otic vesicle, that contains all of the information to develop autonomously into the mature inner ear. We review here the development of the otic vesicle, bringing together classical embryological experiments and recent genetic and molecular...
