Rapid expansion of the spermatogonial stem cell tool box.
R ecently, great technological progress has been achieved in spermatogonial stem cell (SSC) research. In this issue of PNAS, Kanatsu-Shinohara et al. (1) describe yet another important novel use for SSCs. Based on a successful long-term culture protocol for mouse SSCs, this group has designed a way to produce knockout mice from SSCs with an efficiency that is at least comparable with that of em...
متن کامل“Opening” The Mesenchymal Stem Cell Tool Box
Adult mesenchymal stem cells (MSCs) are adherent stromal cells able to self-renew and differentiate into a wide variety of cells and tissues. MSCs can be obtained from distinct tissue sources and have turned out to be successfully manipulated in vitro. As adult stem cells, MSCs are less tumorigenic than their embryonic correlatives and posses another unique characteristic which is their almost ...
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 کاملThe Effect of Caffeic Acid on Spermatogonial Stem Cell-type A Cryopreservation
Background: Cancer treatment methods can lead to male infertility .in this regard, cryopreservation of spermatogonial stem cells (SSC) and cell-to-person transplantation after the course of treatment to resolve the problem of infertility is a good one. The cryopreservation of SSC is an important process as it can help on the return of spermatogenesis. However, during this process, the stem cell...
