(RNS) — Scientists have created a human embryo without the use of sperm or an egg — a true test-tube baby. Such embryos cannot (yet) develop into full-grown human beings. Even if transplanted into a ...

The new method offers researchers a powerful new platform to investigate the molecular mechanisms that control oogenesis, the process by which egg cells develop, and lays important groundwork for ...

The ability to create egg cells from human skin represents one of the most extraordinary frontiers in reproductive science. Researchers are exploring how to reprogramme ordinary body cells into viable ...

Researchers have developed a new stem cell model of the mature human amniotic sac, which replicates development of the tissues supporting the embryo from two to four weeks after fertilization. This is ...

Katsuhiko Hayashi, a developmental geneticist at Osaka University, is working on ways to make what he calls "artificial" eggs and sperm from any cell in the human body. (Kosuke Okahara for NPR) ...

Off a quiet hallway on the top floor of a building at the University of Osaka in Japan, Katsuhiko Hayashi is hatching a revolution. Human embryo science: can the world’s regulators keep pace? He is on ...

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 ...

The press release ‘Ovo Labs announces the first-ever rejuvenation of the human egg, aiming to address the high failure rate of IVF’ was under embargo until 00:01 Friday 9th January 2025. Prof Richard ...
