Cells from patients suffering from various pathologies are being studied. The aim of the different laboratories is to understand the mechanisms of certain conditions, to identify new therapeutic avenues.
«The eye is an organ well suited to cell therapy by stem cells. It is easily accessible and shared with the brain an immunoprivileged property, that is to say a lower risk of rejection in the event of a transplant”, indicates Olivier Goureau, team leader at the Vision Institute and Inserm research director. Very powerful imaging techniques make it possible to see the different retinal layers, and surgical approaches to transplant cells under the retina.
Finally, the human eye shares with the great apes a specific anatomy: the presence of a macula inside which the majority of cone-type photoreceptors are concentrated, which are used to see in everyday life.
“Millions of cells are concentrated on these few square millimeters of surface. As we only become blind when all these cells no longer function, if we manage to replace at least part of them, it is possible to regain vision…
