WebJan 4, 2024 · The germinal epithelium was continuous with unrestricted spermatogonia, and the proliferative, meiotic and spermiogenic phases were defined in all species. In the spermiogenic phase, spermatids were classified as initial, intermediate and final. Only in B. xanthellus in the final phase was there nuclear rotation. Sertoli cells are specifically located in the convolutions of the seminiferous tubules, since this is the only place in the testes where spermatozoa are produced. As the primary support cell of the tubules, they are generally very large and amorphous, with individual cells stretching from the basal lamina to the lumen; their cytoplasm often completely surrounds the germline cells which they are responsible for nursing. Sertoli cells are easily confused with the other cells of the germ…
