The functional mechanism of stria vascularis


, : The functional mechanism of stria vascularis. Otologia Fukuoka 30(SUPPL 2): 771-780

The intracellular potentials of the cells in the stria vascularis were recorded using cell marking technique. The intracellular potentials of marginal cell, intermediate cell and border cell are +79.8 .+-. 5.2 mV, +32.1 .+-. 9.7 mV and +9.7 .+-. 5.8 mV, respectively. The spacial distributions of DC potential and K+ in the stria vascularis were also surveyed with double barrel K sensitive electrode. One large and 1 relatively small electrochemical gradients were found on the intermediate cell-side and the endolymph-side of cell membranes of marginal cell, respectively; this implies the locations of K pumps in the stria vascularis.

The positive endocochlear potential (EP+) and high K+ concentration of the endolymph in the scala media of the mammalian cochlea are unusual. They have long been assumed to be due to a putative K-pump in the luminal membrane of the marginal cells...
