Cytologic structures unique to deiters cells of the cochlea

Abstract: Deiters cells in the gerbil cochlea disclosed unusual ultrastructural features. A sharp transition zone separated the cell body underlying outer hair cells into an upper compartment with numerous organelles and a lower part devoid of structures other than the microtubule stalk. Deiters cells exhibited a unique structure, the rosette complex, which consisted of a core of densely fibrillar trabeculae, enclosed in a filamentous meshwork and surrounded by tubulocisternal endoplasmic reticulum. The dense trabeculae… Show more

“…A similar association of CR with Golgi elements has been encountered in other sites including human eccrine sweat glands (Baron et al, 1984) and cochlear Deiters cells (Spicer and Schulte, 1993). Moreover, a striking development of Golgi cisternae takes place in Deiters cells and pillar cells of neonatal gerbils 14-15 days after birth, at the precise time when CR appears in these cells (Ito et al, 1995).…”

“…However, there is presently no knowledge that CR contains an ATPase or a protein kinase, either of which would utilize high energy phosphate for ion transport, and it is accordingly uncertain as to whether this system demands energy for its presumed function in facilitating ion flow. Moreover, the elaborate display of CR in other sites such as Deiters cells of gerbil cochlea and the human eccrine sweat gland lack an abundance of closely associated mitochondria (Spicer and Schulte, 1993;Baron et al, 1984). If mitochondria associated with CR energize ion movement in type II fibrocytes, the transport mechanism involved in this site must differ from that in Deiters cells and sweat glands.…”

“…R-OTO. perilymphatic K + , including ions effluxing from outer hair cells in the course of auditory transduction (Spicer and Schulte, 1993, 1994a,b, 1996, a silent current (Zidanic and Brownell, 1994) and a nonacoustic parallel current (Spicer et al, 2003). The morphologic data testified further that type II, IV and V fibrocytes relayed these currents to type I fibrocytes in spiral ligament on their way to basal cells of the stria (Spicer and Schulte, 1996;Spicer et al, 2003).…”

“…An arrangement of two structurally and therefore functionally distinct strata in a single cell is shared in the cochlea with inner and outer hair cells and Dieters cells (Spicer and Schulte, 1993;Spicer et al, 2003). Although apparently not encountered often outside the cochlea, a two-tier system offers the advantage of housing in the crowded cochlear epithelium two biologic specializations in the space of one and an uninterrupted secretory surface.…”
