Regenerated hair cells in the neonatal cochlea are innervated and the majority co-express markers of both inner and outer hair cells

Frontiers in Cellular Neuroscience, 2022
After a damaging insult, hair cells can spontaneously regenerate from cochlear supporting cells within the first week of life. While the regenerated cells express several markers of immature hair cells and have stereocilia bundles, their capacity to ...

Human hair follicles operate an internal Cori cycle and modulate their growth via glycogen phosphorylase

Scientific Reports, 2021
Hair follicles (HFs) are unique, multi-compartment, mini-organs that cycle through phases of active hair growth and pigmentation (anagen), apoptosis-driven regression (catagen) and relative quiescence (telogen).

Olfactory receptor OR2AT4 regulates human hair growth

Nature Communications, 2018
Increasing evidence suggest that olfactory receptors can carry additional functions besides olfaction. Here, Chéret et al. show that stimulation of the olfactory receptor ORT2A4 by the odorant Sandalore® stimulates growth of human scalp hair follicles ex

GFI1 regulates hair cell differentiation by acting as an off-DNA transcriptional co-activator of ATOH1, and a DNA-binding repressor

Scientific Reports, 2022
GFI1 is a zinc finger transcription factor that is necessary for the differentiation and survival of hair cells in the cochlea. Deletion of Gfi1 in mice significantly reduces the expression of hundreds of hair cell genes: this is a surprising result, as ...

Transcriptomic Profiling of Zebrafish Hair Cells Using RiboTag

Frontiers in Cell and Developmental Biology, 2018
The zebrafish inner ear organs and lateral line neuromasts are comprised of a variety of cell types, including mechanosensitive hair cells. Zebrafish hair cells are evolutionarily homologous to mammalian hair cells, and have been particularly useful for ...

Activated notch causes deafness by promoting a supporting cell phenotype in developing auditory hair cells. [PDF]

PLoS ONE, 2014
To determine whether activated Notch can promote a supporting cell fate during sensory cell differentiation in the inner ear.An activated form of the Notch1 receptor (NICD) was expressed in early differentiating hair cells using a Gfi1-Cre mouse allele ...

Transcription Factor Reprogramming in the Inner Ear: Turning on Cell Fate Switches to Regenerate Sensory Hair Cells

Frontiers in Cellular Neuroscience, 2021
Non-mammalian vertebrates can restore their auditory and vestibular hair cells naturally by triggering the regeneration of adjacent supporting cells. The transcription factor ATOH1 is a key regulator of hair cell development and regeneration in the inner

Stepwise fate conversion of supporting cells to sensory hair cells in the chick auditory epithelium

iScience, 2023
Summary: In contrast to mammals, the avian cochlea, specifically the basilar papilla, can regenerate sensory hair cells, which involves fate conversion of supporting cells to hair cells. To determine the mechanisms for converting supporting cells to hair

Keratin-mediated hair growth and its underlying biological mechanism

Communications Biology, 2022
Injecting human hair-derived keratin into mice skin accelerates hair growth & formation, as TGFβ2 secretion during hair destruction stimulates epithelial cell death and keratin release, leading to dermal cell condensation & hair growth.

Transmission Disrupted: Modeling Auditory Synaptopathy in Zebrafish

Frontiers in Cell and Developmental Biology, 2018
Sensorineural hearing loss is the most common form of hearing loss in humans, and results from either dysfunction in hair cells, the sensory receptors of sound, or the neurons that innervate hair cells.
