Genetic Effects of Acute Spermatogonial
The genetic effects of one generation of spermatogonial X-irradiation in rats, by a single dose of 6Wr in one experiment and by a fractionated dose of 450r in another, were measured in three generations of their descendants. Estimates of dominant lethal mutation rates-(2 to 3 ) x 1@-4/gamete/r-from litter size differences between irradiated and nonirradiated stock were consistent with previous ...
متن کاملPlasticity of spermatogonial stem cells
There have been significant breakthroughs over the past decade in the development and use of pluripotent stem cells as a potential source of cells for applications in regenerative medicine. It is likely that this methodology will begin to play an important role in human clinical medicine in the years to come. This review describes the plasticity of one type of pluripotent cell, spermatogonial s...
متن کاملDefining the spermatogonial stem cell.
Through the use of donor cells from transgenic rats expressing GFP exclusively in the germline, we have defined culture conditions where male germ cells lose (on STO cells) or maintain (on MSC-1 cells) stem cell activity. A cadre of germ cell transcripts strikingly decrease in relative abundance as a function of testis age or culture time on STO cells, but only a subset of these transcripts (ap...
متن کاملSpermatogonial Stem Cell Niche and Spermatogonial Stem Cell Transplantation in Zebrafish
BACKGROUND Spermatogonial stem cells (SSCs) are the foundation of spermatogenesis, and reside within a specific microenvironment in the testes called "niche" which regulates stem cell properties, such as, self-renewal, pluripotency, quiescence and their ability to differentiate. METHODOLOGY/PRINCIPAL FINDINGS Here, we introduce zebrafish as a new model for the study of SSCs in vertebrates. Us...
متن کاملSpermatogonial culture medium: an effective and efficient nutrient mixture for culturing rat spermatogonial stem cells.
An economical and simplified procedure to derive and propagate fully functional lines of undifferentiated rat spermatogonia in vitro is presented. The procedure is based on the formulation of a new spermatogonial culture medium termed SG medium. The SG medium is composed of a 1:1 mixture of Dulbecco modified Eagle medium:Ham F12 nutrient, 20 ng/ml of GDNF, 25 ng/ml of FGF2, 100 microM 2-mercapt...
