Seminiferous Tubule and Interstitial Cells
This simplified cartoon shows a cross-section region of the seminiferous tubule and the interstitial cells within the male testis. Outside wall at the top and lumen at the bottom. Compare the cartoon to the image of seminiferous tubule histology.
- Interstitial cells (Leydig cell) lie outside of the tubule and produce androgens that are released into the blood stream.
- Peritubular and myoid cells surround the wall of the seminiferous tubule and can generate contractile activity within the wall.
- spermatogonia lie within the periphery of the tubule wall. These are the diploid stem cells that initially proliferate by mitosis and then divide by meiosis to produce the spermatozoa (spermocyte).
- sertoli cells determine the architecture of germ cell differentiation, as they progress from the tubule-enclosing basement membrane to the place of mature spermatozoa release in the tubule lumen.
Schematic diagram to illustrate the essential structure of the spermatogenic epithelium, its relation to the Leydig cells and interstitial space, and the manner in which the Sertoli cells determine the architecture of germ cell differentiation, as they progress from the tubule-enclosing basement membrane to the place of mature spermatozoa release in the tubule lumen (below).
