Dextran Methacryloyl (DexMA) (MW 500000) is a methacrylated dextran that can transform into a cell matrix gel. The gel formed by Dextran Methacryloyl (MW 500000) is non-cytotoxic to fibroblasts; however, cell adhesion in long-term experiments is only marginally effective. Under the influence of the photoinitiator LAP, Dextran Methacryloyl (MW 500000) self-assembles into fibrous hydrogels that target bioactive adhesion sites, providing inherent support and biodegradation activity for tissue cells. Application areas include cell culture, bio 3D printing, and tissue engineering.
