Until recently, the only way to make eggs or sperm was the old-fashioned way: in the ovaries and testes. In the not-too-distant future, it may be possible to use cells from almost any part of the body ...

(Reuters) -Human skin cells may one day be used to create functional human eggs in a step toward helping women have their own genetic children when their natural eggs are dysfunctional, according to ...

Researchers at Oregon Health & Science University (OHSU) have developed a remarkable new way for making human body cells behave like egg cells—a technique that could change the course of the future of ...

A team led by University of Osaka researchers has developed a technique to generate testes from mouse embryonic stem cells ...

WOODS HOLE, Mass. -- While humans can’t renew their reproductive cells and organs if damaged, many invertebrates can as part of whole-body regeneration. Understanding how and why could have major ...

A team of scientists at the University of Seville has identified an essential process that protects DNA integrity in reproductive cells, providing new clues about how organisms avoid genetic defects ...

The fruit fly Drosophila is powerful for studying development and disease and there are many tools to genetically modify its cells. One tool, the Gal4/UAS system, has been a mainstay of Drosophila ...

It’s not just about chromosomes. Or reproductive cells. Or any other binary metric. Many genetic, environmental and developmental variations can produce what are thought of as masculine and feminine ...
