In the lateral of inner and outer HCs rows, inner and outer phalangeal cells (also called the Deiters' cells) reside, respectively.
In the neonatal cochleae of mammals, the Wnt target gene Lgr5 is expressed in a subset of SCs (the pillar cells, inner phalangeal cells, and Deiters' cells) [54], and these endogenous Lgr5+ cells maintain mitotic quiescence.
