prdm1a drives a fate switch between hair cells of different mechanosensory organs [PDF]

Nature Communications
Vertebrate inner ear mechanosensory hair cells detect sound and gravitational forces. Additionally, fishes have homologous lateral line hair cells in the skin that detect water vibrations for orientation and predator avoidance.

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 ...

Transcriptomic characterization of dying hair cells in the avian cochlea

Cell Reports, 2021
Summary: Sensory hair cells are prone to apoptosis caused by various drugs including aminoglycoside antibiotics. In mammals, this vulnerability results in permanent hearing loss because lost hair cells are not regenerated.

Apicosome: Newly identified cell-type-specific organelle in mouse cochlear and vestibular hair cells

iScience, 2023
Summary: Cochlear and vestibular hair cells are highly specialized sensory receptors for hearing and balance. Here, we report a serendipitous identification of a hair-cell-specific organelle in neonatal mouse inner ear, which we name “apicosome.” The ...

Hair cell regeneration [PDF]

Current Opinion in Neurobiology, 2008
The mammalian inner ear largely lacks the capacity to regenerate hair cells, the sensory cells required for hearing and balance. Recent studies in both lower vertebrates and mammals have uncovered genes and pathways important in hair cell development and have suggested ways that the sensory epithelia could be manipulated to achieve hair cell ...

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 ...

Signaling pathways in hair aging

Frontiers in Cell and Developmental Biology, 2023
Hair follicle (HF) homeostasis is regulated by various signaling pathways. Disruption of such homeostasis leads to HF disorders, such as alopecia, pigment loss, and hair aging, which is causing severe health problems and aesthetic concerns.

Efferent control of the electrical and mechanical properties of hair cells in the bullfrog's sacculus. [PDF]

PLoS ONE, 2010
Hair cells in the auditory, vestibular, and lateral-line systems respond to mechanical stimulation and transmit information to afferent nerve fibers. The sensitivity of mechanoelectrical transduction is modulated by the efferent pathway, whose activity ...

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.

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
