Differentiation of the müllerian (paramesonephric) duct epithelium in the rat
1Department of Embryology, Faculty of Medicine, Charles University, Prague.
Differentiation of the Müllerian duct epithelium was studied in 15- to 21-day female rat foetuses. The proximal segment of the Müllerian duct is formed by the 15th day; it runs parallel to the Wolffian duct and the two are wrapped in a common basement membrane. On the 16th day the genital ducts are clearly separate; the Müllerian duct has a slit-like lumen and is lined with simple columnar epithelium. Throughout the whole of the given period the epithelium retains a relatively indifferent appearance. Characteristic findings from the 18th day include the apical migration of centrioles and the formation of solitary cilia.
