[The multitasking Sertoli cell]

Area of Science:

• Reproductive Biology
• Cell Biology
• Endocrinology

Background:

• Sertoli cells are essential for male reproductive organ development and adult spermatogenesis.
• They establish the blood-testis barrier, segregating testicular compartments.
• Sertoli cells produce over 60 proteins, including critical hormones and growth factors.

Purpose of the Study:

• To elucidate the multifaceted roles of Sertoli cells in male reproductive physiology.
• To describe the protein production and functional significance of Sertoli cells.
• To outline the phagocytic capabilities and tumor diversity of Sertoli cells.

Main Methods:

• Literature review and synthesis of existing research on Sertoli cell function.
• Analysis of protein expression and hormonal functions.
• Examination of phagocytosis and cellular interactions.
• Review of pathological characteristics of Sertoli cell tumors.

Main Results:

• Sertoli cells produce anti-Müllerian hormone, inhibin, activin, androgen-binding protein, and ferritin.
• They maintain spermatogenesis by regulating the microenvironment and hormone levels.
• Sertoli cells exhibit phagocytic activity against apoptotic germ cells and bacteria.
• Sertoli cell tumors present a wide range of histological appearances.

Conclusions:

• Sertoli cells are indispensable for male fertility, regulating both development and ongoing sperm production.
• Their diverse protein repertoire and phagocytic functions highlight their central role in testicular homeostasis.
• Understanding Sertoli cell biology is crucial for diagnosing and treating related pathologies, including tumors.
