Cell migration and activated PI3K/AKT-directed elongation in the developing rat Mullerian duct.

ABSTRACT: In vertebrates, the Müllerian duct elongates along the Wolffian duct, a mesonephric structure that is required for Müllerian duct formation. Recently, several genes required for initial Müllerian duct formation have been identified. However, the precise mechanism of Müllerian duct elongation remains to be elucidated. In this study, we investigated dynamic morphological changes in the elongating Müllerian duct in rat urogenital ridges in organ culture manipulated by microincision and/or chemical inhibitors. Mechanical division of the developing Müllerian duct showed that epithelial cells of the Müllerian duct actively migrate along the anterior-posterior axis independent of the proliferative expansion of the anterior portion of the duct. We found that the PI3K/AKT signaling pathway is activ
