Jones and Corwin have proposed that a subpopulation of cells localized in the supporting cell layer in mammals may be progenitor cells responsible for limited hair cell regeneration in vestibular organs such as the utricle.

Etymology
The word utricle comes from the Latin utriculus, meaning 'small bag' or 'pouch', and is the same root as uterus ('womb'). So the utricle in the inner ear is a tiny pouch, which explains its name and its role in helping with balance.
