New Bioink for Printing Muscle Tissue
November 7, 2023 | Terry Sharrer
“Now, researchers from the Terasaki Institute for Biomedical Innovation (TIBI) in Los Angeles have come up with a novel, improved bioink to enhance 3D-printed skeletal muscle constructs and overcome the limitations of autologous transfer. . . . The bioink is composed of a biocompatible gelatin-based hydrogel called gelatin methacryloyl (GeIMA), myoblast cells, and PLGA microparticles coated with IGF-1 designed to slowly release the hormone as the particles degraded. Poly(lactic-co-glycolic acid) or PLGA is one of the most effective biodegradable polymeric nanoparticles due to its sustained-release properties, low toxicity and biocompatibility. A control version of the bioink was created without IGF-1. MORE
