“…), and capable of changing shape throughout the cycle of the seminiferous epithelium, often exhibiting deep invaginations (Figure S2) of the nuclear membrane that is surrounded by vimentin intermediate filaments. The nucleolus is very large and stains intensely (Schulze et al ., ), with three distinct parts (tripartite), with most nucleoli have two satellite chromocenters in rodent species, although three satellite structures are found occasionally in a small percentage of mice (Kushida et al ., ; Guttenbach et al ., ) and rat Sertoli cells (Hess & Vogl, ). In some species, the satellite chromocenters form donut shapes, but these structures often are out of the plane of section.…”

SUMMARY It has been one and a half centuries since Enrico Sertoli published the seminal discovery of the testicular ‘nurse cell’, not only a key cell in the testis, but indeed one of the most amazing cells in the vertebrate body. In this review, we begin by examining the three phases of morphological research that have occurred in the study of Sertoli cells, because microscopic anatomy was essentially the only scientific discipline available for about the first 75 years after the discovery. Biochemistry and molecular biology then changed all of biological sciences, including our understanding of the functions of Sertoli cells. Immunology and stem cell biology were not even topics of science in 1865, but they have now become major issues in our appreciation of Sertoli cell’s role in spermatogenesis. We end with the universal importance and plasticity of function by comparing Sertoli cells in fish, amphibians, and mammals. In these various classes of vertebrates, Sertoli cells have quite different modes of proliferation and epithelial maintenance, cystic vs. tubular formation, yet accomplish essentially the same function but in strikingly different ways.
