Scientists created human egg cells from skin cells — then used them to make embryos

A scientist works on cells in a laboratory.

Scientists have created human eggs in the lab using a similar process to the one used to clone the famous Dolly the sheep, then used in vitro fertilization (IVF) to turn them into embryos.

Although this method is far from being used in a clinical setting, the hope is that it could eventually pave the way to new fertility treatments.
