[[Auditory hair cell]]s are the mechanical [[sensor]]s of sound waves in the [[inner ear]], and the [[stereocilia]], which are [[actin]]-rich protrusions of different heights on the apical surfaces of hair cells, are responsible for the [[transduction]] of [[sound]] [[wave]]s into electrical signals. As a crucial [[actin]]-binding and bundling protein, [[espin]] is able to cross-link actin filaments and is therefore necessary for [[stereocilia]] morphogenesis. Using advanced super-resolution stimulated emission depletion microscopy, we imaged espin expression at the sub-diffraction limit along the whole length of the stereocilia in outer hair cells and inner hair cells in order to better understand espin's function in the development of stereocilia
