Mullerian duct

The Müllerian (paramesonephric) duct is formed from a finger-shaped invagination of the coelomic epithelium at the upper pole of the mesonephros. The Mullerian duct is comprised of three cell types: the epithelial cells, which form the inner tube (Mullerian duct epithelium), the mesenchymal cells, which surround the tube (Mullerian duct mesenchyme) and the coelomic epithelial cells, which define the external borders of the duct (Mullerian coelomic epithelium). The Müllerian duct differentiates into the female reproductive tract.
