For people going through , the journey begins long before a pregnancy test turns positive.
Cambridge researchers have identified a key genetic switch that helps human embryos develop in the days immediately after fertilisation.
Using a highly precise gene-editing technique, scientists showed that a gene called NANOG plays a crucial role in helping an embryo form the cells that eventually become the human body.
The findings offer new insights into fertility, IVF and early pregnancy loss, reminding us just how much of pregnancy's earliest development happens before many people even know they're expecting.
Scientists have, for the first time, used an extremely precise genome editing technique called base editing to study gene function in human embryos. They found that a gene called NANOG is essential for forming the future body from an embryo.
