title: Postnatal transformation and location of mitoses in the epithelium lining the mouse vomeronasal organ.
abstract: The structure and the postnatal transformation of the epithelium lining the vomeronasal organ of the mouse was observed. The medial wall of the middle segment of the organ was lined with the sensory epithelium similar to the olfactory epithelium, and was not undergone any transformation in the postnatal life. The lateral wall of the middle segment and the entire lumen of the rostral segment were covered with the stratified cuboidal epithelium in the newborn mouse. The stratified cuboidal epithelium transformed into the ciliated columnar epithelium with advancing ages, excepting in the vomeronasal duct where the epithelium changed into the stratified squamous one. In the mouse aged between 4 and 10 days, mitotic figures were observed not only in the boundary between the sensory epithelium and the ciliated columnar one in the middle segment, but also in the rostral segment of which the entire lumen was covered with the ciliated columnar epithelium.
