Abstract
Saini et al . recently reported in Cell Stem Cell that nicotinamide can suppress the expression of a broad set of genes in induced pluripotent stem cell-derived retinal pigment epithelium (iPS-RPE) cells that may contribute to age-related macular degeneration (AMD) (1). There are ample reasons to be excited about their findings, and many opportunities for future work. In this commentary, I will begin by providing background about the etiology of AMD before outlining some of the challenges of studying AMD using iPS-RPE. With that context in place, I will describe which elements of the Saini et al . study I find most exciting, and discuss potential future directions.
