During this process, the germ line stem cells embedded in the supporting Sertoli cells of the seminiferous tubules divide mitotically to expand the pool of spermatogonia; after two meiotic divisions, these actions will give rise to spermatocytes and haploid spermatids.
Morphofunction features two compartments: (i) interstitial or intertubular, containing cells and fibers of connective tissue, blood and lymphatic vessels and Leydig cells, the main source of androgen in the body, (ii) tubular, formed by seminiferous tubules, which are structured with its outer portion to the internal: tunica propria, the seminiferous epithelium and lumen (ROOIJ, 1998).
Basically, germ cell transplants consist in gathering germ cells from a donor and injecting them into the seminiferous tubules of a receptor; PGC's colonize the basal membrane of receptor's seminiferous tubules in search of a nich where they can develop into stem cells.

Animal models lacking GRs showed morphological changes, including low number of Sertoli cells, low number of spermatocytes and spermatids, and decreased seminiferous tubule formation.
Structural characteristics and seminiferous tubule development of the testes
The developing germ cells of different stages of spermatogenesis are also observed in the central seminiferous tubule and adjacent tubules (Fig.
Taking into account the fact that the weight of the testis was reduced, it can be deduced that the seminiferous tubule diminished as a consequence of Cd exposure, thus reducing the carrying capacity of the testis.

Subsequently, gonocytes are located in the basement membrane of seminiferous tubule and differentiate into spermatogonial stem cells (SSCs) (de Rooij and Grootegoed, 1998; Brinster, 2002).
Points corresponding to the seminiferous tubule, intertubule, blood and lymph vessels were counted in twenty random fields for each animal.
