IBEC researchers have laid the groundwork for faster advances in 3D bioprinting for regenerative medicine by creating a system of ink and matrices that offers a solid basis for tissue regeneration.

Due to their high water content, hydrogels are highly attractive biomaterials for 3D printing as efficient ‘surrogates’ for the extracellular matrix, onto which cells can be cultured. However, while they are relatively easy to produce using a method called extrusion printing, their stability and structural integrity can weaken when they’re in contact with biological fluids or extracellular matrices.
