Sertoli cell

An elongated cell in the seminiferous tubules of the testis which secretes sex hormone-binding globulin and provides a micro-environment for developing sperm.

Sertoli cells secretions
• Anti-Müllerian hormone—Early foetal life.
• Inhibin and activins—Post-pubertal; regulate FSH secretion.
• Androgen binding protein—Concentrates testosterone in the seminiferous tubules, stimulating spermiogenesis.
• Oestradiol aromatase—Converts testosterone to 17 beta oestradiol for spermatogenesis.
• Glial cell-derived neurotrophic factor—Drives spermatogonial stem cell renewal during perinatal period.
• ERM transcription factor—Maintains spermatogonial stem cell in the adult testis.
• Transferrin—Iron ion delivery.
