Comparative evaluation of decellularized porcine liver matrices crosslinked with different chemical and natural crosslinking agents

The objective of this study was to compare the scaffold properties of porcine liver ECM crosslinked with different agents (glutaraldehyde, genipin, and quercetin) to find the best strategy for producing a decellularized matrix with optimal and stable characteristics for transplantation and regeneration. The properties examined include mechanical properties, material stability, immunogenicity, and angiogenic capacity. Scaffolds were implanted into the greater omentum of rats, and their abilities to induce immune cell subpopulation invasion and neovascularization were evaluated. The results show that genipin crosslinking of decellularized liver matrices increased the mechanical and proangiogenic properties and reduced the inflammatory response in vivo.
