Biomedical applications of gelatin methacryloyl hydrogels

Abstract Gelatin methacryloyl (GelMA) has attracted the widespread interest of researchers because its excellent biocompatibility, biodegradability, and moldability. Various structures have been constructed from GelMA hydrogel, including 3D scaffold, injectable gel, bio-printed electrospun fibrous membrane via precise fabrication methods such as light-induced crosslinking, extrusion printing, electrospinning, or microfluidics. Due to unique characteristics simple preparation, hydrogel demonstrates superior performance promising potential in a broad range biomedical applications involving wound healing, drug delivery, biosensing, tissue regeneration. This review integrates sufficient research works on hydrogels regeneration tissues skin, tendon, bone, cartilage, blood vessel, cardiovascular system, addition organ-on-a-chip, providing critical present work offering future implications.
