(A) Dextran-allyl isocyanate-ethylamine (Dex-AE)/polyethylene glycol diacrylate (PEGDA) hydrogel promotes neovascularization: Precise structure manipulation results in rapid, efficient, and functional neovascularization (Sun et al., 2011).

(C) Chemokine sequestration by the starPEG-heparin hydrogel networks (depicted in A) through strong electrostatic interactions of heparin derivatives and chemokines (depicted in B) results in a reduced immune cell invasion, which in turn, lowers the concentrations of inflammatory chemokines and ultimately allows the inflammation to subside (Lohmann et al., 2017).
