Two adaptation processes in auditory hair cells together can provide an active amplifier [PDF]

Biophys. J. 85, 191-203 (2003), 2003
The hair cells of the vertebrate inner ear convert mechanical stimuli to electrical signals. Two adaptation mechanisms are known to modify the ionic current flowing through the transduction channels of the hair bundles: a rapid process involves calcium ions binding to the channels; and a slower adaptation is associated with the movement of myosin ...

Hair cell damage recruited Lgr5-expressing cells are hair cell progenitors in neonatal mouse utricle [PDF]

Frontiers in Cellular Neuroscience, 2015
Damage-activated stem/progenitor cells play important roles in regenerating lost cells and in tissue repair. Previous studies reported that the mouse utricle has limited hair cell regeneration ability after hair cell ablation.

Notch signaling limits supporting cell plasticity in the hair cell-damaged early postnatal murine cochlea. [PDF]

PLoS ONE, 2013
In mammals, auditory hair cells are generated only during embryonic development and loss or damage to hair cells is permanent. However, in non-mammalian vertebrate species, such as birds, neighboring glia-like supporting cells regenerate auditory hair ...

Lgr5-Positive Supporting Cells Generate New Hair Cells in the Postnatal Cochlea [PDF]

Stem Cell Reports, 2014
The prevalence of hearing loss after damage to the mammalian cochlea has been thought to be due to a lack of spontaneous regeneration of hair cells, the primary receptor cells for sound.

Advances in Regenerative Stem Cell Therapy in Androgenic Alopecia and Hair Loss: Wnt pathway, Growth-Factor, and Mesenchymal Stem Cell Signaling Impact Analysis on Cell Growth and Hair Follicle Development

Cells, 2019
The use of stem cells has been reported to improve hair regrowth in several therapeutic strategies, including reversing the pathological mechanisms, that contribute to hair loss, regeneration of hair follicles, or creating hair using the tissue ...

The transcriptome of utricle hair cell regeneration in the avian inner ear [PDF]

Journal of Neuroscience, 2014
Sensory hair cell loss is the major cause of hearing and balance disorders. Mammals are incapable of sustained hair cell regeneration, but lower vertebrates can regenerate these mechano-electrical transducers.

Sensory hair cell death and regeneration in fishes

Frontiers in Cellular Neuroscience, 2015
Sensory hair cells are specialized mechanotransductive receptors required for hearing and vestibular function. Loss of hair cells in humans and other mammals is permanent and causes reduced hearing and balance.

Metabolic Profiling of Cochlear Organoids Identifies α‐Ketoglutarate and NAD+ as Limiting Factors for Hair Cell Reprogramming [PDF]

Advanced Science
Cochlear hair cells are the sensory cells responsible for transduction of acoustic signals. In mammals, damaged hair cells do not regenerate, resulting in permanent hearing loss.

Cellular reprogramming with ATOH1, GFI1, and POU4F3 implicate epigenetic changes and cell-cell signaling as obstacles to hair cell regeneration in mature mammals

eLife, 2022
Reprogramming of the cochlea with hair-cell-specific transcription factors such as ATOH1 has been proposed as a potential therapeutic strategy for hearing loss.

Myc and Fgf Are Required for Zebrafish Neuromast Hair Cell Regeneration. [PDF]

PLoS ONE, 2016
Unlike mammals, the non-mammalian vertebrate inner ear can regenerate the sensory cells, hair cells, either spontaneously or through induction after hair cell loss, leading to hearing recovery.
