Cell-mediated delivery and targeted erosion of growth factor-crosslinked hydrogels. Non-covalently assembled hydrogels were formed by the crosslinking of polysaccharide-derivatized star copolymers by dimeric HEP-binding growth factors. The receptor-mediated erosion of the hydrogels enabled the cell-responsive targeted delivery of VEGF. Reproduced with permission from Ref.[171b], copyright (2010) John Wiley & Sons.
