  The bulb region of tubulobulbar complexes lacks a surrounding cuff of actin filaments. In this region, the Sertoli cell plasma membrane becomes intimately related to a cistern of endoplasmic reticulum (Figure A). The bulbs eventually separate or “bud” from the complexes and are degraded by the Sertoli by: 6. Sertoli cell nucleus showing typical indentations (arrows) and prominent nucleolus, lying near the basal lamina (Bl). Lateral Sertoli cell-Sertoli cell junctions (Jct) are seen on both sides of the.   The Sertoli cell, which is the supporting cell of spermatogenesis, has an important role in the endocrine and paracrine control of by:   During postnatal life, Sertoli cells undergo extensive proliferative activity, which is essential for the expansion of the testis cords and to produce the final number of Sertoli cells in adulthood (Figure A and B) (reviewed in).Because each Sertoli cell supports a fixed number of germ cells, the number of adult Sertoli cells quantitatively determines sperm output, with decreases .

  In the preparation of Sertoli cell plasma membranes, obtained on sucrose discontinuous gradient, 5′-nucleotidase was increased fold in specific activity relative to the initial homogenate (± IU/mg protein vs. ± IU/mg protein, n=3) and acid phosphatase was increased fold (± IU/mg protein vs. ± Sertoli cells are the only type of somatic cells in the seminiferous epithelium and play critical roles in regulating spermatogenesis by building a niche for germ cell development, providing nutrition to germ cells, and removing AGC and RB by phagocytosis. Sertoli cell phagocytosis is the most noticeable. Book. Sertoli Cell Toxicants induced the formation of cytoplasmic vacuoles close to the plasma membrane in the SerW3 Sertoli cell line.

ABSTRACT: Membrane rafts from Sertoli cell cultures were isolated as detergent‐insoluble glycosphingolipid‐enriched (DIG) fractions on the basis of their enriched content of glycosphingolipids and cholesterol and the resulting insolubility in 1% Triton X‐ and their low buoyant density. Because lipid rafts have been implicated in numerous cell functions, including cell signaling and.   The general organization of the seminiferous epithelium is the same for all male mammals. This epithelium is organized into tubules whose general structures are dictated by two somatic cells, the stromal peritubular myoid cells that reside on the exterior of the tubule and the Sertoli cells, which are highly branched cells that extend from the basement membrane to the lumen of the tubule . Sertoli cell marker serotonin receptor mRNA is expressed in Sertoli cells from day, 6-mo, and mo normal testes but not in those from mo regressed testes. PMID: , PMID: SCF (stem cell factor) a substance produced by isolated rat Sertoli cells in culture, is a Sertoli cell . The seminiferous epithelium is composed of two populations of cell types, supportive epithelial elements, the highly polarized Sertoli cells and differentiating elements, the germ cells. The Sertoli cell is a tall, narrow, columnar cell that extends from the basal lamina .
