Researchers grew a fully mature human egg in a lab
Researchers in the UK and the US have taken human eggs in their most early stage and developed them to maturity in a lab for the first time. It's a big achievement that could open up new avenues for infertility treatment and give scientists a better understanding of how the egg development process works and how it can go wrong. While this has been done before in mice, experiments of which have resulted in live offspring, this is the first time it has been done with human eggs.
