Decellularized ECM-Derived Hydrogels: Modification and Properties

Extracellular matrix (ECM) hydrogels are water-swollen fibrillary three-dimensional (3D) networks where collagen type I is the major component. The hierarchical network formed by the polymerization of tropocollagen molecules with enhanced properties is an attractive template for generating biomaterials. The mammalian tissue source from which collagen is extracted and its consequent modification are variables that impact the physicochemical and biological properties of the collagen network. This chapter has the purpose to provide a review of the research of different strategies to modify and characterize the properties of decellularized ECM-derived hydrogels in the context of safe biomaterials with immunomodulatory properties.
