– Hyaluronic Acid Methacryloyl (HAMA) with a molecular weight of 150 kDa is a biocompatible methacrylated derivative of hyaluronic acid. HAMA is utilized as an ink for 3D printing hydrogels, exhibiting rapid photoreactive responses, quick gelation speeds, and stable hydrogel properties. Under ultraviolet light exposure, HAMA efficiently induces gelation in conjunction with phenyl-2,4,6-trimethylbenzoylphosphinate (LAP). The integration of HAMA with tissue-specific extracellular matrix (ECM) materials, such as pancreatic ECM (pECM), is poised to become a vital source material for organ-like tissue cultivation.
