Injectable hydrogels have been paid much attention as an injectable matrix for therapeutic applications due to easy applications based on minimally invasive technique. Such a system makes cells, drugs and bioactive molecules easily incorporated in situ by a simply syringe injection of their aqueous solutions at target sites. Various types of hydrogels formed in situ through physical or chemical cross-linking reaction were reported. Among these reactions, enzymatic reaction using peroxidase has received much attention to fabricate in situ cross-linkable hydrogels due to biocompatibility and good controllability of the reaction rate. This cross-linking system enable hydrogels not only to be formed under mild conditions for short time period but also to be strengthened due to chemical cross-link, which are major issue in the development of in situ forming hydrogels. In addition, their physico-chemical properties can be controlled easily by varying the concentrations of catalysts. In this study, various kinds of in situ forming hydrogels via a peroxidase-mediated cross-linking reaction were developed as injectable matrices. To investigate the usefulness of the hydrogels as injectable materials for therapeutic applications, in vitro and in vivo studies have been performed using various bioactive molecules, cells and animal models. Obtained results demonstrated that our enzyme-mediated injectable hydrogels are promising materials for therapeutic applications including tissue regeneration and drug delivery.
