block14_09.jpg - Fig. 3 & 4, Q-1-b, Testis, h&e; 93W7206, Testis, ihExamination of the tubule epithelium reveals two kinds of cells: a proliferating population of spermatogenic cells and a non-proliferating population, the Sertoli cells (S). The Sertoli cells are considerably fewer and can be recognized by their elongate, trangular, pale-staining nuclei and conspicuous nucleolus. The Sertoli cell extends from the periphery of the tubule to the lumen. The spermatogenic cells consist of successive generations arranged in concentric layers. The spermatogonia (Sg) are found at the periphery. The spermatocytes (Sc), most of them have large round nuclei with a distinctive chromatin pattern, come to lie above the spermatogonia. The spermatid (Sp) consists of one or two generations and occupies the site closest to the lumen.In high magnification, it reveals a population of Leydig cells (LC) that occur in small clusters and lie in the interstitial space between adjacent tubules. They are readily identified by their location, small round nucleus and eosinophilic cytoplasm.
