Single-cell transcriptomic analysis defines hair cell and supporting cell types in the zebrafish inner ear, and reveals homologies with cells in the mammalian ear.
Direct reprogramming of somatic cells to an inner ear sensory hair cell-like state provides an experimental platform to identify causes and treatments for hair cell loss and hearing deficits.

The pressure of fluid in the inner ear is controlled by opening of cellular valves in the endolymphatic sac to allow for regulated transepithelial fluid flow.
Genome-wide RNA-seq analysis of single cells of the developing mouse endolymphatic sac reveals its molecular-cellular architecture and a model for salt and fluid absorption required for acquisition of normal inner ear structure and function.
Manipulations of Wnt signalling in the chicken embryo reveal how it controls in a dose-dependent manner the formation of the neurosensory territories of the early developing inner ear.
A dynamic confrontation between Notch signalling and the transcription factor Lmx1a at the borders of the developing inner ear sensory patches regulates their segregation and the positioning of their boundaries.

Size regulation of the otic vesicle, the progenitor of the inner ear, is mediated by mechanical feedback involving fluid influx, hydraulic pressure, and tissue mechanics.
RNA-Seq analysis and in vivo validation via genetic approach uncover that Scrt2 and Celf4 are expressed in inner ear auditory neurons throughout development.
