title: [Researches on Mullerian duct morphogenesis in birds : II. Experimental study].
abstract: Certain points in the Mullerian duct morphogenesis, and the role played by the Wolffian duct in oviduct formation, were studied with some experimental methods (by stopping the mullerian anlage with a mechanical obstacle, or by a localized irradiation with X-rays).The results emphasize the independent formation and evolution of the two tissues, the inner epithelium and the mesenchyme which compose the young mullerian anlage.The inner epithelium is formed by the cranio-caudad outgrowth of a primitive anlage, formed at the level of the ostium, and induced by the Wolffian duct.The peripheric mesenchyme is formed "in situ", from the mullerian strip, which itself is induced by the Wolffian duct.In Birds, oviduct development depends upon the primary ureter, by means of the double inductive action exerted by the Wolffian duct upon both tissues constituting the Mullerian duct anlage.
