Molecular mechanisms controlling Sertoli cell proliferation and differentiation.
Whereas spermatogonia stem cells continually divide to populate the testis with developing germ cells, the major supporter of this process, the Sertoli cell, ceases to proliferate shortly after birth in rodents and during puberty in higher primates including men. Because Sertoli cells are capable of supporting only a fixed number of germ cells, the timing of Sertoli cell exit from the cell cycl...
متن کاملMolecular Mechanisms Involved in Sertoli Cell
26 27 Sertoli cells provide the physical support and the necessary environment to germ 28 cell development. Among the products secreted by Sertoli cells, lactate —the preferred 29 energy substrate for spermatocytes and spermatids— is present. Considering the essential 30 role of lactate on germ cell metabolism, it is supposed that Sertoli cells must ensure its 31 production even in adverse cond...
متن کاملRelaxin and Sertoli cell proliferation.
Immature Sertoli cells proliferate and several factors affect their number, including the follicle stimulating hormone (FSH), testosterone, estradiol and several paracrine growth factors. Using a primary culture of Sertoli cells isolated from 15-day old Wistar rats we have shown that relaxin stimulates Sertoli cell proliferation through the activation of MEK/ERK1/2 and PI3K/AKT pathways. In con...

Sertoli cells provide the physical support and the necessary environment for germ cell development. Among the products secreted by Sertoli cells, lactate, the preferred energy substrate for spermatocytes and spermatids, is present. Considering the essential role of lactate on germ cell metabolism, it is supposed that Sertoli cells must ensure its production even in adverse conditions, such as t...
متن کاملSystems Modeling of Molecular Mechanisms Controlling Cytokine-driven CD4+ T Cell Differentiation and Phenotype Plasticity
Differentiation of CD4+ T cells into effector or regulatory phenotypes is tightly controlled by the cytokine milieu, complex intracellular signaling networks and numerous transcriptional regulators. We combined experimental approaches and computational modeling to investigate the mechanisms controlling differentiation and plasticity of CD4+ T cells in the gut of mice. Our computational model en...
