Spermatogonial

Earlier studies showed promise using so-called spermatogonial cells from the testes of mice. ❋ Unknown (2008)

"Nevertheless, it appears that these unique specialized spermatogonial cells could be an easily obtained and manipulated source of stem cells with exactly the same capability to form new tissues that we see in embryonic stem cells." ❋ Unknown (2007)

The researchers used spermatogonial cells, extracted from the testicles of deceased human organ donors. ❋ Unknown (2010)

Several key regulators of spermatogonial stem cell self-renewal have been identified, but knowledge of molecules that control spermatogonial stem cell differentiation is lacking, ❋ Unknown (2010)

After removing the spermatogonial cells from the testes, the researchers put them into a special media. ❋ Unknown (2010)

Here we used transposon-mediated mutagenesis to knock out genes in rat spermatogonial stem cells. ❋ Zsuzsanna Izsvák (2010)

Ian Gallicano and colleagues used germ-derived pluripotent stem cells, which are made from the spermatogonial stem cells. ❋ Unknown (2010)

By manipulating STAT3, researchers identified a key regulator of spermatogonial stem cell self-renewal. ❋ Unknown (2010)

Male factor infertility: Milestone in autotransplantation of human spermatogonial stem cells ❋ Rebecca Drake (2010)

We discussed spermatogenesis -- how we got from a diploid spermatogonial stem cell to a haploid spermatid -- and then spermiogenesis -- the process by which the spermatids acquire the features of spermatozoa: tails, acrosomes and the like. ❋ Scicurious [email protected] (2010)

The current breakthrough represents the culmination of many years of work by Dr. Rafii and his lab, including their research in converting adult mouse spermatogonial stem cells to endothelial cells (Nature, September 2007) and in deriving stable, copious endothelial cells from human embryonic stem cells (Nature Biotechnology, Jan. 17, 2010). ❋ Unknown (2010)

By the time they get here they have traveled through about 6-7 meters of male reproductive tract in a journey (most of which is not under their own power) that takes roughly 20 days from the first division of the spermatogonial stem cell until they arrive in the cauda. ❋ Scicurious [email protected] (2010)
