The Notch Ligand JAG1 Is Required for Sensory Progenitor Development in the Mammalian Inner Ear
In mammals, six separate sensory regions in the inner ear are essential for hearing and balance function. Each sensory region is made up of hair cells, which are the sensory cells, and their associated supporting cells, both arising from a common progenitor. Little is known about the molecular mechanisms that govern the development of these sensory organs. Notch signaling plays a pivotal role i...
متن کاملThe Notch ligand Jagged1 is required for inner ear sensory development.
Within the mammalian inner ear there are six separate sensory regions that subserve the functions of hearing and balance, although how these sensory regions become specified remains unknown. Each sensory region is populated by two cell types, the mechanosensory hair cell and the supporting cell, which are arranged in a mosaic in which each hair cell is surrounded by supporting cells. The propos...
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...
متن کاملTBX1 is required for inner ear morphogenesis.
TBX1 is thought to be a critical gene in the pathogenesis of del22q11/DiGeorge syndrome (DGS). Morphological abnormalities of the external ear and hearing impairment (conductive or sensorineural) affect the majority of patients. Here we show that homozygous mutation of the mouse homolog Tbx1 is associated with severe inner ear defects that prevent the formation of the cochlea and of the vestibu...
متن کاملDistinct expression patterns of notch family receptors and ligands during development of the mammalian inner ear
The cochlea and vestibular structures of the inner ear labyrinth develop from the otic capsule via step-wise regional and cell fate specification. Each inner ear structure contains a sensory epithelium, composed of hair cells, the mechanosensory transducers, and supporting cells. We examined the spatio-temporal expression of genes in the Notch signaling pathway, Notch receptors (Notch1-4) and t...
