Chuck Bednar for redOrbit.com - Your Universe Online For the first time, researchers from the University of Cambridge and the Weizmann Institute in Chiacago have created the precursors to egg and sperm using human stem cells. While these...
Latest Germ cell Stories
A new study, from the Stanford University School of Medicine and Montana State University, demonstrates that, when implanted into the reproductive system of a mouse model, stem cells created from adult, infertile men will yield primordial germ cells.
Shawn Ahmed, PhD, shows that tweaking specific cellular mechanisms helps tiny worms overcome infertility through a pathway of cellular interactions that result in long life.
Johns Hopkins researchers have discovered an unexpected phenomenon in the organs that produce sperm in fruit flies: When a certain kind of stem cell is killed off experimentally, another group of non-stem cells can come out of retirement to replace them.
A new generation of high yield plants could be created following a fundamental change in our understanding of how plants develop.
The Y chromosome is a symbol of maleness, present only in males and encoding genes important for male reproduction. But live mouse offspring can be generated with assisted reproduction using germ cells from males with the Y chromosome contribution limited to only two genes: the testis determinant factor Sry and the spermatogonial proliferation factor Eif2s3y.
Mammalian females ovulate periodically over their reproductive lifetimes, placing significant demands on their ovaries for egg production.
Scientists recently completed a study that shows the possibility that stem cells work towards maturity at an earlier stage than originally thought.
Regenerative-medicine researchers have moved a promising step closer to helping infertile, premenopausal women produce enough eggs to become pregnant.
Researchers reporting in the April 27 issue of the journal Cell , a Cell Press publication, have devised a new and improved method for producing genetically modified animals for use in scientific research.
Ordinarily, embryonic stem cells exist only a day or two as they begin the formation of the embryo itself.
