The use of human embryo stem cells in an attempt to treat age-related macular degeneration: scientists at Hadassah Hospital in Jerusalem embarked on a clinical trial at the end of 2015 (seeAuthorisation for a new clinical trial based on human embryo stem cells). Since then, five patients have received an injection of retinal pigment cells derived from human embryo stem cells. According to Professor Benjamin Reubinoff who is leading the trial, “the elderly persons’ vision remained stable and did not deteriorate as it would have done without transplantation”. The aim is to offer early treatment for ARMD. However, the “efficacy of the treatment has yet to be established”.
