Sertoli cells are found inEach seminiferous tubule of the testis is lined on its inside by two types of cells: male germ cells (spermatogonia) and Sertoli cells.
Sertoli cells provide nutrition to the germ cells; the sperm heads become embedded in them after spermiogenesis, and they also secrete factors that help in spermiogenesis under the influence of FSH.
The regions outside the tubules contain the interstitial (Leydig) cells, which secrete androgens.
Cholecystokinin is secreted by the duodenal mucosa, progesterone by the corpus luteum and adrenaline by the adrenal medulla.
Hence Sertoli cells are found in seminiferous tubules and provide nutrition to germ cells.
