The mesonephric tubular structure (epoophoron) in the human mesosalpix in the 40s has been investigated with the electron microscope. The tubule with 0.5 mm in diameter is lined by a simple columnar epithelium 10-12μm in height, and surrounded by a basal lamina and smooth muscle cells. The epithelial cell has an ellipsoidal nucleus, poorly developed rough endoplasmic reticulum, small Golgi apparatus, rod-shaped mitochondria with lamellar cristae, vacuoles, lipid droplets and lysosomes. In addition, abundant glycogen particles and numerous free polysomes are characteristic in the cytoplasm, and there are many microvilli and typical kinocilia (9+2 type) with rootlets and basal bodies in the apical part of the cell. No secretory granules are seen. There are cellular debris or degenerated cells with pyknotic nuclei in the lumen as well as in the epithelium. Therefore, it is considered that this mesonephric tubular structure is only an embryonal vestige without any functional significance.
