Gene Expression and Epigenetic Signatures of Germ Cell-Derived Pluripotent Stem Cells and Embryonic Stem Cells
2012
Germ cell-derived Pluripotent Stem Cells (gPSCs) are pluripotent stem cells that originate from Spermatogonial Stem Cells (SSCs) of the testis. Several reports in the last few years have shown that it is possible to isolate and enrich the SSC population by different approaches and even reprogram these in vivo multipotent cells to gPSCs in vitro. As these cells could be an alternative to circumvent the ethical objections regarding the use of Embryonic Stem Cells (ESCs) for therapeutic approaches, these SSC-derived gPSCs were characterized in several studies comparatively to the gold standard of pluripotency, the ESCs. The results provide great promise that gPSCs can be of importance for pra…
Germ Cell Differentiation from Pluripotent Cells
2013
Infertility is a medical condition with an increasing impact in Western societies with causes linked to toxins, genetics, and aging (primarily delay of motherhood). Within the different pathologies that can lead to infertility, poor quality or reduced quantity of gametes plays an important role. Gamete donation and therefore demand on donated sperm and eggs in fertility clinics is increasing. It is hoped that a better understanding of the conditions related to poor gamete quality may allow scientists to design rational treatments. However, to date, relatively little is known about human germ cell development in large part due to the inaccessibility of human development to molecular genetic …
