Retinal pigment epithelium (RPE) degradation is central to the onset and progression of age-related macular degeneration (AMD), a growing and currently incurable form of blindness.Due to its key role in maintaining the retinal structure and homeostasis, cell replacement of the RPE monolayer has emerged as a promising therapy to rescue visual acuity in AMD patients.Thanks to the tremendous progress of pluripotent stem cell technologies over the last decade, a potentially unlimited new source for RPE transplantation has reached clinical trials. This review summarizes the methods by which pluripotent stem cell-based RPE cells are produced for transplantation, the delivery methods currently being adopted and the latest clinical outcomes with regard to the treatment of AMD.
视网膜色素上皮(RPE)的退化是年龄相关性黄斑变性(AMD)发病和进展的核心,AMD 是一种日益严重且目前无法治愈的失明形式。由于 RPE 单层在维持视网膜结构和动态平衡方面的关键作用,RPE 细胞的替代已成为一种有前途的治疗方法,可以挽救 AMD 患者的视力。得益于过去十年多来多能干细胞技术的巨大进步,一种潜在的无限新的 RPE 移植来源已进入临床试验。本综述总结了用于移植的基于多能干细胞的 RPE 细胞的生产方法、目前采用的输送方法以及关于 AMD 治疗的最新临床结果。
