The numbers in the germline vary dramatically throughout embryo, foetal and offspring development 21. About 100,000 mitochondria are estimated to be present in the mouse oocyte at the time of ...

Over half of our genomes consists of thousands of remnants of ancient viral DNA, known as transposable elements, which are widespread across the tree of life. Once dismissed as the 'dark side' of the ...

For the first time, a team of stem cell researchers in Israel have created mouse embryos in the lab without using any eggs or sperm and watched them grow outside the womb. The successful ...
