Mammalian spermatogenesis is a complex process in which male germ-line stem cells develop to ultimately form spermatozoa. Spermatogonial stem cells, or SSCs, are found in the basal compartment of the seminiferous epithelium. They self-renew to maintain the pool of stem cells throughout life, or they differentiate to generate a large number of germ cells. A balance between SSC self-renewal and d...
Spermatogenesis is a complex process that involves many elements. However, until now, little is known at the molecular level about spermatogenesis in poultry. Here we investigated microRNAs and their target genes that may be involved in germ cell development and spermatogonial in chicken. We used next-generation sequencing to analyze miRNA expression profiles in three types of germline cells: p...
Background: The basis of spermatogenesis is the spermatogonial stem cells (SSCs). The concentration of SSCs is very small. However, a system that supports the proliferation and maintenance of SSCs in vitro could be used to preserve and expand SSCs numbers as well as increase success in transplantation. It is a new avenue to restore spermatogenesis in azoospermia subjects. Objective: Proliferati...
conclusions large amounts of preclinical studies have been made of stem cells and there is an increasing interest to perform these studies within the human population but preclinical studies are insufficient; therefore, much more and efficient studies should be conducted to evaluate the efficacy and safety of stem cells. context musculoskeletal injuries may be painful, troublesome, life limitin...
Purpose: To compare the effect of laminin and gelatin on short-term culture of spermatogonial stem cells (SSCs) from neonatal mouse testes.Materials and Methods: Cell suspension containing SSCs were isolated from testes of 6 day-old mice and cultured in the presence of Glial-derived neuroterophic factor (GDNF), Epidermal Growth Factor (EGF) and Basic Fibroblastic Growth Factor (bFGF) on laminin...
