Photodegradable Hydrogels for On‐Demand Modeling of Age‐Related Spatiotemporal ECM Deformation

open access: yesSmall, EarlyView.
A light‐tunable PEG hydrogel enables on‐demand, spatiotemporal modeling of drusen‐like ECM bulges in the aging outer retina. By precisely controlling bulge size, the platform reveals how retinal pigment epithelium morphology adapts to topographical changes without disrupting actin cytoskeleton or polarity, effectively mimicking early ageing before ...
