Biomimetic hydrogels with immobilized ephrinA1 for therapeutic angiogenesis.

abstract：:New aspects concerning the mechanism of formation of chitosan physical hydrogels without any cross-linking agent were studied. The gelation took place during the evaporation of a hydroalcoholic solution of chitosan. We first demonstrated that it was possible to form a physical hydrogel from a hydrochloride form of chi...
