type III spiral ligament fibrocyte 2011-07-11T03:40:50Z tension fibroblast type 3 spiral ligament fibrocyte A spiral ligament fibrocyte that is located in the deepest part of the inferior spiral ligament, directly lining the bony otic capsule. Distinguished from ion-transporting Type I and II fibrocytes, it utilises actin-myosin stress fibres and anchoring interactions to regulate basilar membrane tension. It has an elongated morphology, is most numerous in the basal, high-frequency cochlea, and expresses contractile and cytoskeletal proteins in mice, including α‑smooth muscle actin, non‑muscle myosin II, caldesmon, and the water channel Aquaporin‑1(Mahendrasingam et al., 2011; Kelly et al., 2012). type 3 otic fibrocyte spiral ligament fibrocyte
