Ready-To-Use 3D Human Retinal Pigment Epithelial Spheroids - 24 plates

Age-related macular degeneration (AMD) is characterized in its early stages by the presence of extracellular deposits known as drusen that accumulate between the basal surface of the retinal pigmented epithelium and Bruch's membrane an extracellular matrix complex that separates the neural retina from the capillary network in the choroid [1]. Several studies have shown that drusen contains a variety of protein and lipid components [2]. Although liver is the primary biosynthetic site for most of these molecules retinal pigment epithelial (RPE) cells locally synthesize a number of drusen components [2]. The respective contributions of RPE-derived and plasma-derived molecules to the biogenesis of drusen and the relevant molecular interactions leading to drusen depositions however have not been fully identified. One of the major limitations is that RPE cells once isolated from the eye tend to dedifferentiate into myofibroblasts in conventional 2D cell culture. Recent studies have shown that 3D retinal pigment epithelial cell spheroids form and maintain a well-differentiated epithelium in 3D cell culture [3]. ScienCell Research Laboratories as a result has developed ready-to-use 3D human retinal pigment epithelial spheroids (SP3D-HRPEpiS). 3D RPE spheroids exhibit the differentiated epithelial cell marker cytokeratin-18 and deposit apolipoprotein ApoE a prominent drusen constituent. The 3D RPE spheroid model is an ideal way to model drusen in vitro and study the pathogenesis of related diseases such as AMD.
