IT IS a world first for stem cells. Twelve people with Stargardt’s macular dystrophy will be treated with retinal cells made from human embryonic stem cells (hESCs) in the hope of improving, or at least halting loss of sight. In Stargardt’s, retinal pigment epithelial cells start to die off in childhood, probably due to a defective gene. As RPEs help to maintain and support adjacent photoreceptor cells which capture light, their loss leads to blindness. People in the trial will be those whose vision has deteriorated to the point where they can see the movement of their own hands,
