Which of the following would be a function of the cells of sertoli (nurse cells)
a. secretion of inhibin
b. these cells secrete the androgen binding protein
c. divide by meiosis to provide a constant source of spermatogonia
d. provides nourishment for developing sperm
e. these cells from the blood-testes barrier

All are the function of sertoli cells except option c.

Explanation:

Please note the correct question should be "Which of the following would "not" be a function of the cells of Sertoli".

Sertoli cells, also termed as nurse cells, are somatic cells present in seminiferous tubule.

These cells play important role in the process of spermatogenesis, that is, production of sperm and formation of testes.

They also form hemato-testes barrier or blood-testes barrier or sertoli cell barrier.

They release various types of proteins such as inhibin, androgen-binding protein, and antimullerian hormone.

Sertoli cells being somatic in nature divide by mitotic division and not by meiotic division.

Germ cells, not sertolic cells, provide constant supply of spermatogonia.

Thus, option c is not a function of sertoli cells
