[Light and electron microscopy studies of the development of Reissner's membrane in the cochlear duct of guinea pig fetuses].

Differentiation of the Reissner's membrane (membrana vestibularis) is described in precisely dated guinea pig fetuses. In newborn and adult animals, the Reissner's membrane consists of two layers of flat cells, an epithelial one and a mesenchymal one, separated by a basement membrane. The epithelial part develops from the initially simple columnar… CONTINUE READING
