Question

What cells are responsible for the blood-testis barrier?

Answer 1

Sertoli cells:

1. Sertoli cells are responsible for the blood-testis barrier which divides the seminiferous epithelium into two compartments, basal and adluminal.
2. The presence of the blood-testis barrier allows Sertoli cells to control the environment in which germ cells (i.e., spermatocytes, spermatids, and sperm) develop.
