British surgeons are to take part in the first trial in patients of a human embryonic stem cell therapy to gain approval from regulators in Europe. 

Surgeons at Moorfields Eye Hospital in London will inject cells into the eyes of 12 patients with an incurable eye disease called Stargardt's macular dystrophy, one of the main causes of blindness in young people. 

The clinical trial, designed to investigate the safety and tolerance of the groundbreaking therapy, is due to begin in December having received approval from the UK's Medicines and Healthcare products Regulatory Agency on Thursday. It is the first trial in people of a stem cell therapy to receive the go ahead from regulators in any European country.
