Ser·to·li cells

(sĕr-tō'lē),
elongated cells in the seminiferous tubules that ensheathe spermatogenic cells, providing a microenvironment that supports spermiogenesis and spermatocytogenesis; they secrete androgen-binding protein and establish the blood-testis barrier by forming tight junctions with adjacent Sertoli cells.
Synonym(s): nurse cells

Ser·to·li cells

(ser-tō'lē selz)
Elongated cells in the seminiferous tubules that ensheathe spermatids, providing a microenvironment that supports spermiogenesis; they secrete androgen-binding protein and establish the blood-testis barrier by forming tight junctions with adjacent Sertoli cells.

Sertoli cells

Elongated cells in the walls of the seminiferous tubules that closely surround (‘nurse’) the spermatids, encouraging spermatogenesis. Together, they provide a blood-testis barrier and secrete an androgen-binding protein. (Enrico Sertoli, Italian histologist, 1842–1910).

Sertoli cells

or

nurse cells

large nutritive cells occurring in the wall of SEMINIFEROUS TUBULES that serve to nourish the developing sperm. They are named after the Italian histologist, E. Sertoli.
