Schematic depiction of the fabrication of micropatterned hydrogels where (a) a volume of GelMA precursor is placed on a silanized substrate and then (b) covered with a photomask before being (c) exposed to UV light for photopolymerization. (d) Uncrosslinked hydrogel is then rinsed with PBS before (e) removal of the photomask (f) to retrieve the micropatterned hydrogel.
