    Studysummary This study found that applying both dehydrothermal treatment and carbodiimide crosslinking improved the mechanical properties of porcine acellular dermal matrix scaffolds without added cytotoxicity, suggesting potential applications in tissue engineering. Our plain-language summary of this paper — not a Tressless recommendation.
    The study demonstrated that combining dehydrothermal (DHT) and carbodiimide (EDC) crosslinking significantly enhanced the physicochemical properties and biostability of porcine acellular dermal matrix (PADM) scaffolds. This combined treatment improved tensile strength and crosslink density without compromising the three-dimensional architecture or introducing cytotoxicity. The DHT+EDC crosslinked scaffolds showed increased resistance to degradation and thermal treatment compared to scaffolds treated with either method alone, indicating a synergistic effect beneficial for tissue engineering applications.
