Advanced Healthcare Materials, EarlyView.ABSTRACT In vitro arterial models offer ethical and robust alternatives for vascular research but require cytocompatible materials that replicate physiological mechanics. Poly(vinyl alcohol) (PVA) hydrogels produced by directional freezing and salting‐out (PVA DFSO) are anisotropic yet lack stability for cell culture. Herein, methacrylated PVA (PVA‐MA)
