The association of these cells with developing cells, and Sertoli cells
tumours of the ovary: a clinicopathologic and immunohistochemical study of 54 cases.
Other duties of sertoli cell
are phagocytosis of extra proteins of germ cells and preventing the release of sperm (4).
Nucleus of Sertoli cells
and germ cells (spermatogonia type A, pachytene primary spermatocyte and round spermatid) were counted in 20 seminiferous tubules per rat (n = 10 animals [group.
747 [micro]m), due to the activity of the spermatogonia that are grouped in cysts delimited by Sertoli cells
, of acidophilic coloration; they have round large nucleus and nucleoli, (103.
Specifically, cholesterol is involved in the plasticity of Sertoli cell
membranes (Papadopoulos, 2005) and acts in particular as a membrane strengthener.
Testicular juvenile granulosa cell and Sertoli cell
tumours: a clinicopathological study of 29 cases from the Kiel Paediatric Tumour Registry.
Spermatogenesis is a complex and tightly-regulated process of cell proliferation and differentiation leading to production of mature spermatozoa from Spermatogonial Stem Cells (SSCs) The coordination of SSCs self-renewal and differentiation is regulated by growth factors produced by somatic cells surrounding SSCs, particularly Sertoli cells
When Examination the transverse -sections of testicular tissue of male mice treatment dose(T1A) observed disintegration and spacing Seminiferous tubules from each other within the testis sector(Figs 3a,b), alienation in epithelial germ cells for Some of these tubules(Figs 3b,c,d), inflammatory infiltration(Figs 3a,e), sertoli cells

PYOMETRA AND SERTOLI CELL
TUMOR IN A DOG WITH PERSISTENT MULLER DUCT
Elongation of the spermatids continues until the flagellum is fully formed, which is concomitant with extrusion of most of the cell cytoplasm, the so-called residual body, which is phagocytosed by the Sertoli cell
(Weinbauer et al.
tumors are characterized by elongate cells with basal nuclei and moderate to abundant basophilic cytoplasm, arranged in a palisading manner around the central lumina of tubules.
204) SF-1 is another promising nuclear stain with reported positivity in all adult and juvenile granulosa cell tumors (194,202) and most fibromas, thecomas, Sertoli cell
tumors, and steroid cell tumors (202,206) and reported negativity in yolk sac tumors, (194) carcinoid tumors, and primary and metastatic ovarian carcinomas.
