The Sertoli cell in vivo and in vitro
Cell Biology and Toxicology, 1992The Sertoli cell extends from the basement membrane of the seminiferous tubule towards its lumen; it sends cytoplasmic processes which envelop different generations of germ cells. The use of Sertoli cell culture began to develop in 1975. To reduce germ cell contamination immature animals are generally used as Sertoli cell donors.

Sertoli cells of lizards are characterized by variable size, abundant smooth and rough endoplasmic reticulum, multivesicular bodies, lipid vacuoles probably related to the spermatogenic cycle, and mitochondria of normal size. The cytoskeleton contains actin, particularly abundant in the cell periphery, vimentin all around the nucleus and throughout the

Histopathology, 1990
Histological study of testicular biopsies from infertile men showing Sertoli‐cell‐only tubules due to hypogonadotropic hypogonadism, cryptorchidism, oestrogen treatment, chemotherapy or Del Castillo's syndrome, revealed four types of Sertoli cells: (1) normal adult mature cells showing an indented nucleus, grossly triangular in shape with a prominent ...

SummaryA Sertoli cell tumour occurred in a cryptorchid testis of a 1‐year‐old cat with no signs of feminization. The tumour showed intratubular growth without interstitial infiltration and the neoplastic cells appeared polymorphous and vacuolated. Mitotic figures were rare.

The cytoskeleton of terminally differentiated mammalian Sertoli cells is one of the most elaborate of those that have been described for cells in tissues. Actin filaments, intermediate filaments and microtubules have distinct patterns of distribution that change during the cyclic process of spermatogenesis. Each of the three major cytoskeletal elements

Spermatogenesis and the Sertoli Cell
1983The pioneering studies by Greep and co-workers (Greep et al. 1936) established that two gonadotrophic hormones FSH and LH could be extracted from mammalian pituitary glands. From these observations and the studies of Smith on hypophysectomised animals (Smith 1930) the concept was developed that FSH acted on the seminiferous tubules and LH on the ...

There is more than a century and a half that the polarized Sertoli cell which extends from the base of the seminiferous tubule to its lumen has been identified as being a “nurse cell” for germ cells. This Sertoli cell nursing function relies on a cytosqueleton displaying all possible properties of plasticity to adapt to the cyclicity of spermatogenesis,
