Cochlear13
  • The stria vascularis of the cochlear duct is a capillary loop in the upper portion of the spiral ligament (the outer wall of the cochlear duct). (wikipedia.org)
  • The stria vascularis is part of the lateral wall of the cochlear duct. (wikipedia.org)
  • During mouse embryonic development, a subpopulation of neural crest cell-derived melanocytes migrates and incorporates into a subregion of the cochlear epithelium, forming the intermediate cell layer of the stria vascularis. (jneurosci.org)
  • In characterizing the molecular differentiation of developing peripheral auditory structures, we discovered that hepatocyte growth factor ( Hgf ) is expressed in the future stria vascularis of the cochlear epithelium. (jneurosci.org)
  • Its receptor tyrosine kinase, c-Met , is expressed in the cochlear epithelium and melanocyte-derived intermediate cells in the stria vascularis. (jneurosci.org)
  • Genetic dissection of HGF signaling via c-MET reveals that the incorporation of the melanocytes into the future stria vascularis of the cochlear duct requires c-MET signaling. (jneurosci.org)
  • The cochlea is a bony, spiral-shaped chamber that contains the cochlear duct of the membranous labyrinth. (medscape.com)
  • The sense of hearing is provided by receptors within the cochlear duct. (medscape.com)
  • Beginning in the fifth week of development, the auditory vesicle also gives rise to the cochlear duct, which contains the spiral organ of Corti and the endolymph that accumulates in the membranous labyrinth. (medscape.com)
  • The vestibular wall separates the cochlear duct from the perilymphatic scala vestibuli, a cavity inside the cochlea. (medscape.com)
  • The basilar membrane separates the cochlear duct from the scala tympani, a cavity within the cochlear labyrinth. (medscape.com)
  • The lateral wall of the cochlear duct is formed by the spiral ligament and the stria vascularis, which produces the endolymph. (medscape.com)
  • The hair cells develop from the lateral and medial ridges of the cochlear duct, which together with the tectorial membrane make up the spiral organ of Corti. (medscape.com)
Spiral ligament1
Semicircular ducts1
  • The semicircular canals enclose the slender semicircular ducts. (medscape.com)
Endolymph1
Scala1
  • The stria vascularis is a nonsensory structure that is essential for auditory hair cell function by maintaining potassium concentration of the scala media. (jneurosci.org)
Auditory1
  • The utricular division of the auditory vesicle also responds to angular acceleration, as well as the endolymphatic sac and duct that connect the saccule and utricle. (medscape.com)
Function1
Development1
  • SIGNIFICANCE STATEMENT We found the roles of hepatocyte growth factor (HGF) signaling in stria vascularis development for the first time and that lack of HGF signaling in the inner ear leads to profound hearing loss in the mouse. (jneurosci.org)
