Pluripotency of male germline stem cells.
The ethical issues and public concerns regarding the use of embryonic stem (ES) cells in human therapy have motivated considerable research into the generation of pluripotent stem cell lines from non-embryonic sources. Numerous reports have shown that pluripotent cells can be generated and derived from germline stem cells (GSCs) in mouse and human testes during in vitro cultivation. The gene ex...
متن کاملGenetic and Epigenetic landscape of Germline Stem Cells
Elucidating the critical epigenetics events involved in differentiation and reprogramming of cells to primordial germ cells (PGCs) is among the interesting issues in stem cell research. Here, I will talk about critical transcription factors and global hypomethylation in development of germ cells. Evidence strongly suggests that the earliest PGCs emerging in the E7.25 mouse embryo epiblast have...
متن کاملMaintaining the male germline: regulation of spermatogonial stem cells.
Spermatogonial stem cells (SSCs) are a self-renewing population of adult stem cells capable of producing progeny cells for sperm production throughout the life of the male. Regulation of the SSC population includes establishment and maintenance of a niche microenvironment in the seminiferous tubules of the testis. Signaling from somatic cells within the niche determines the fate of SSCs by eith...
متن کاملRegulation of pluripotency in male germline stem cells by Dmrt1.
Spermatogonial stem cells (SSCs) present the potential to acquire pluripotency under specific culture conditions. However, the frequency of pluripotent cell derivation is low, and the mechanism of SSC reprogramming remains unknown. In this study, we report that induction of global DNA hypomethylation in germline stem (GS) cells (cultured SSCs) induces pluripotent cell derivation. When DNA demet...
متن کاملRestoration of fertility in infertile mice by transplantation of cryopreserved male germline stem cells.
BACKGROUND The development of a spermatogonial transplantation technique has provided new possibilities for the treatment of male infertility. Previous studies have shown that spermatogonial stem cells could reinitiate spermatogenesis after cryopreservation and reintroduction into the seminiferous tubules of infertile recipient males, and this raised the possibility of banking frozen stem cells...
