Mechanosensitive hair cells vary widely in morphology and regenerative capacity across vertebrate organs and species. To investigate their underlying transcriptomic diversity, we integrated human, mouse, chicken, and zebrafish single-cell and single-nucleus RNA sequencing datasets and assembled a cross-species atlas of hair cells spanning organs, developmental stages, and species....

No actionable change; this is foundational basic science with no immediate clinical application.
Understanding the genetic blueprint of hair cell diversity and regeneration across species could accelerate the search for strategies to restore hearing in humans.
- 01Single-cell transcriptomic atlas maps gene activity in hair cells across multiple vertebrate species and organs.
- 02Compares hair cells from hearing and balance organs to uncover shared and unique genetic features.
- 03Aims to explain why some species can regenerate hair cells while mammals, including humans, cannot.
- 04Purely basic science; no therapeutic interventions tested.
- 05Provides a reference dataset for future hair cell regeneration and hearing restoration research.
Hair cells across diverse vertebrate species and organs show transcriptomic diversity related to regenerative capacity.
