Development of endolymph during maturation of the mammalian inner ear

Abstract
The development of the elemental composition in the endolymphatic space was investigated during embryologic and early post natal maturation of the CBA/CBA mouse. At birth the elemental distribution was similar in the endo- and perilymphatic spaces. Mature composition of endolymph was reached 6–8 days post partum. The maturation of endolymph corresponded well in time with the morphological maturation of the stria vascularis.
