Electron microscopy research on Leydig cells in breeding boards

摘要

Leydig Cells or interstitial endocrinocytes are very numerous at an adult boar, where they occupy 20-30% of the testicular tissue(1). Aims : The electron microscopy research approach studies of the Cytoplasm , Cell Organelles and the type of junctional complexes which they realize between the adjacent cells. The electron microscopy reveals the two types of interstitial endocrinocytes : small and spindle cells, with few organelles , and big cells with a cytoplasm rich in vesicles, lipid inclusions and pigments. These studies have influence over the quality of the seminal material.
