Expression of Ocn-95 at early embryonic stages. At E9.5–E10.5, the growing endolymphatic duct (arrowhead) and the dorsal part of the otic vesicle are strongly labeled. At E12, the endolymphatic duct, the forming semicircular canals (sc), and the cochlea (c) are stained. Magnification: ×25 (E9.5), ×17 (E10.5), and ×6 (E12).
