The day when human sperm and eggs can be grown in the laboratory has inched a step closer, with the discovery of a way to recreate a crucial developmental step in a dish 1. “Epigenetic reprogramming ...

Scientists have created human eggs containing genes from adult skin cells, a step that someday could help women who are infertile or gay couples have babies with their own genes but would also raise ...

In our cells, our DNA carries chemical or 'epigenetic' marks that decide how genes will be used in different tissues. Yet in the group of specialised ...
