Seminiferous Tubule Each seminiferous tubule has a basement membrane that separates it from the surrounding Leydig cells, the peritu- bular cells (myoid cells) and the connective tissue. There are two diva chamber types in seminiferous tubules: somatic cells (Sertoli cells) and rudiment cells (Fig. Sertoli Cells Sertoli cells are the sustentacular cells in seminiferous tubules, which variety the outstanding stall mass in them. Construct of Sertoli cells They are irregularly shaped cells that are extended from the basement membrane into the lumen of seminiferous Fig. Sperms are married to the apical membrane of (1) and spermatoginia (2) lie in the bound of the tubules, and sperms in disparate stages of development in the middle of the tubule (3 to 6).
