The receptors 1 and 2 of fibroblast growth factor (FGFR1 and FGFR2, respectively) have been observed in all types of testicular cells. Culture on extracellular matrix (ECM) has been observed to lead to initiation of differentiation in spermatogonial stem cells (SSCs). The present study was carried out to investigate whether FGFR1 and FGFR2 play a role in SSCs differentiation. Following isolatio...
Background: Varicocele is a dilated vein of the pampiniform plexus that cause to det-rimental time-dependent effects so this study describes the effect of varicocele on the level of IL-6 and interferon gamma in serum and testis tissue, number of sertoli and spermatogonia cells, seminiferous tubules diameter and sperm activity in immature rats. Methods: Thirty six immature rats, 5-6 weeks aged ...
Observations in patients with an activating mutation of fibroblast growth factor receptor 3 (FGFR3) suggest a role for FGFR3 signalling in promoting proliferation or survival of germ cells. In this study, we aimed to identify the FGFR3 subtype and the ontogeny of expression during human testis development and to ascertain whether FGFR3 signalling is linked to germ cell proliferation and the pat...
