PCP and Wnt pathway components act in parallel during zebrafish mechanosensory hair cell orientation [PDF]

Nature Communications, 2019
Planar cell polarity (PCP) regulates hair cell orientation in the zebrafish lateral line. Here, the authors show that mutating Wnt pathway genes (wnt11f1, fzd7a/b, and gpc4) causes concentric hair cell patterns not regulated by PCP, thus showing PCP/Wnt ...

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.

The role of epigenetic modifications in sensory hair cell development, survival, and regulation

Frontiers in Cellular Neuroscience, 2023
The cochlea is the sensory organ in the periphery, and hair cells are its main sensory cells. The development and survival of hair cells are highly controlled processes.

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 ...

Single-cell transcriptomic profiling of the zebrafish inner ear reveals molecularly distinct hair cell and supporting cell subtypes

eLife, 2023
A major cause of human deafness and vestibular dysfunction is permanent loss of the mechanosensory hair cells of the inner ear. In non-mammalian vertebrates such as zebrafish, regeneration of missing hair cells can occur throughout life.

Tmc Reliance Is Biased by the Hair Cell Subtype and Position Within the Ear

Frontiers in Cell and Developmental Biology, 2021
Hair cells are heterogenous, enabling varied roles in sensory systems. An emerging hypothesis is that the transmembrane channel-like (Tmc) proteins of the hair cell’s mechanotransduction apparatus vary within and between organs to permit encoding of ...

Ontogenetic development of inner ear hair cell organization in the New Zealand carpet shark Cephaloscyllium isabellum

Frontiers in Ecology and Evolution, 2022
IntroductionThe inner ear hair cells of fishes can provide insight into the early evolution of vertebrate inner ear structure. Fishes represent some of the first vertebrates to evolve auditory capacity, and the same basic structure, the sensory hair cell,

Initiation of Supporting Cell Activation for Hair Cell Regeneration in the Avian Auditory Epithelium: An Explant Culture Model

Frontiers in Cellular Neuroscience, 2020
Sensorineural hearing loss is a common disability often caused by the loss of sensory hair cells in the cochlea. Hair cell (HCs) regeneration has long been the main target for the development of novel therapeutics for sensorineural hearing loss.
