Claudius cells are considered as supporting cells within theorgan of Corti in thecochlea. These cells extend fromHensen's cells to the spiral prominence epithelium, forming the outer sulcus. They are in direct contact with theendolymph of thecochlear duct. These cells are sealed viatight junctions that prevent flow of endolymph between them.Boettcher cells are located immediately under Claudius cells[1] in the lower turn of the cochlea.[2]
Claudius cells are named after German anatomist,Friedrich Matthias Claudius (1822–1869).
