Retinal organoids: A breakthrough in the therapy of dry age-related macular degeneration
Age-related macular degeneration (AMD), which is divided into dry and wet forms, poses a significant threat to the vision of older people worldwide. Despite its prevalence, the exact molecular mechanisms underlying the damage to retinal pigment epithelial (RPE) cells and photoreceptor cells (PCs) in dry AMD are still poorly understood. Therefore, there is an urgent need to develop human retinal models that can mimic dry AMD. This research, published in the journal Genes & Diseases by a team from the Third Medical Center of the Chinese PLA General Hospital, the Medical School of the Chinese PLA General Hospital, and the Chinese Academy of Medical Sciences & Peking Union Medical College, used sodium iodate-stimulated human retinal organoids (ROs) to create a model of dry AMD. Building on their previous work, which demonstrated the presence of abundant RPEs and PCs in ROs after 186 days of differentiation,…
