Scientists move step closer to making IVF eggs from skin cells

Procedure could overcome common forms of infertility and help people have children who share their DNA

Scientists are a step closer to making IVF eggs from patients' skin cells after adapting the procedure that created Dolly the sheep, the first cloned mammal, more than two decades ago.

The work raises the prospect of older women being able to have children who share their DNA, and to overcome common forms of infertility caused by a woman's eggs becoming damaged by disease or cancer treatment.
