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.

Sertoli cells - elongated cells in the seminiferous tubules to which spermatids are attached during spermiogenesis. Synonym(s): nurse cells
Sertoli columns

The large amount of nucleolar-like material in nuclei of the nurse cells is due to the fact that the nuclei of these cells are polyploid, and very active in the production of RNA.
Although RNP is one of the main products transferred by the nurse cells into the oocyte, the AgN[O.
It is worth noting that, while bacteria and cyanobacteria are often enclosed in vacuoles of both nurse cells and oocytes, yeasts are consistently in direct contact with the cell's cytoplasm.
The nurse cells engulfed by the developing oocyte during oogenesis remain in the egg throughout embryogenesis as spherical, refractile cells with pycnotic nuclei (Zihler, 1972; Honegger et al.
