Figure 2. Synthesis methods of engineered synthetic hydrogels. From: Synthetic Hydrogels Mimicking Basement Membrane Matrices to Promote Cell-Matrix Interactions.

Photo-polymerization of two water-soluble polymers (A) and copolymerization of one monomer and one multi-functional monomer (B) via covalent reaction after UV irradiation. (C) Direct chemical reaction of a branched polymer with a di-functional crosslinking agent. (D) Electrostatic interactions of an anionic polymer with divalent cations yields an “ionotropic” hydrogel. (E) Encapsulated cells in an engineered biofunctionalized hydrogel exhibiting adhesive ligand, growth factor-binding domain and MMP-degradable crosslinks.
