Regulation of Sertoli cell and germ cell differentation.
Unwanted childlessness affects approximately one in six couples worldwide. According to the World Health Organization, in nearly 40% of cases the cause can be attributed to the female, in 20% to the male, in 25% to both, and in 15% the cause remains unknown. The incidence of male factor infertility in the general population is approximately 7%. The majority of these men experience irreversible ...
متن کاملSertoli-Sertoli and Sertoli-germ cell interactions and their significance in germ cell movement in the seminiferous epithelium during spermatogenesis.
Spermatogenesis is the process by which a single spermatogonium develops into 256 spermatozoa, one of which will fertilize the ovum. Since the 1950s when the stages of the epithelial cycle were first described, reproductive biologists have been in pursuit of one question: How can a spermatogonium traverse the epithelium, while at the same time differentiating into elongate spermatids that remai...
متن کاملEffect of germ cell depletion on levels of specific mRNA transcripts in mouse Sertoli cells and Leydig cells
It has been shown that testicular germ cell development is critically dependent upon somatic cell activity but, conversely, the extent to which germ cells normally regulate somatic cell function is less clear. This study was designed, therefore, to examine the effect of germ cell depletion on Sertoli cell and Leydig cell transcript levels. Mice were treated with busulphan to deplete the germ ce...
متن کاملSertoli cell condition medium can induce germ like cells from bone marrow derived mesenchymal stem cells
Objective(s): Although many researchers have confirmed induction of germ cells from bone marrow mesenchymal stem cells (BMMSCs), there are no reports that confirm spontaneous differentiation of germ cells from BMMSCs. In this study, we have evaluated the effect of adult Sertoli cell condition medium (SCCM) as a mutative factor in the induction of germ cells from BMMSCs. Materials and Methods: ...
متن کاملParacrine regulation of Sertoli cell proliferation
The Sertoli cell is a highly differentiated somatic cell in the seminiferous epithelium of the testis. This cell is of prime importance for both testicular development and spermatogenesis. Sertoli cells proliferate up to the start of puberty and, due to their nursing functions, the final Sertoli cell number is well correlated to the amount of germ cells produced by the adult testis. The physiol...
