Description
Summary:The spheroid culture system has gained significant attention as an effective in vitro model to mimic the in vivo microenvironment. Even though numerous studies were focused on developing spheroids, the structural organization of encapsulated cells within hydrogels remains a challenge. Allylated gelatin or GelAGE is used as a bioink due to its excellent physicochemical properties. In this study, GelAGE was evaluated for its capacity to induce spontaneous spheroid formation in encapsulated HepG2 cells. GelAGE was synthesized and characterized using 1HNMR spectroscopy and ninhydrin assay. Then the physicochemical and biological attributes of GelAGE hydrogel was examined. The results demonstrate that GelAGE has remarkable ability to induce the encapsulated cells to self-organize into spheroids.
