Pluripotent Stem Cells from Testis
1.1 Importance of Spermatogonial Stem Cells (SSCs) Spermatogonial stem cells (SSCs) are undifferentiated germ cells that balance self-renewing and differentiating divisions to maintain spermatogenesis throughout adult life. This is a productive stem cell system that produces millions of spermatozoa each day while also maintaining rigorous quality control to safeguard germline integrity. SSCs ar...
متن کاملO-3: Identification and Characterization of Repopulating Spermatogonial Stem Cells from The Adult Human Testis
Background: This study was conducted to identify and characterize repopulating spermatogonial stem cells (SSCs) in the adult human testes. Materials and Methods: Testes biopsies from obstructive azoospermic patients and normal segments of human testicular tissue were used. Flow cytometry, real time PCR and immunohistochemical analysis were performed. Purified human spermatogonia were transplant...
متن کاملStem cells in the testis
The origin and development of the spermatogenic cell lineage is reviewed, as well as spermatogonial kinetics in adult nonprimate mammals in relation to the cycle of the seminiferous epithelium, the emphasis being on spermatogonial stem cells. A hypothesis is presented for the transition from foetal germ cells, gonocytes, to adult type spermatogonia at the start of spermatogenesis. An overview i...
متن کاملGeneration of Pluripotent Stem Cells from Neonatal Mouse Testis
Although germline cells can form multipotential embryonic stem (ES)/embryonic germ (EG) cells, these cells can be derived only from embryonic tissues, and such multipotent cells have not been available from neonatal gonads. Here we report the successful establishment of ES-like cells from neonatal mouse testis. These ES-like cells were phenotypically similar to ES/EG cells except in their genom...
متن کاملEmbryonic stem cell-like cells derived from adult human testis.
BACKGROUND Given the significant drawbacks of using human embryonic stem (hES) cells for regenerative medicine, the search for alternative sources of multipotent cells is ongoing. Studies in mice have shown that multipotent ES-like cells can be derived from neonatal and adult testis. Here we report the derivation of ES-like cells from adult human testis. METHODS Testis material was donated fo...
