Comparison of the mechanical properties of: native bovine (b), GA-b, decell b pericardium; native porcine (p), GA-p, decell p pericardium. (A) Elastic modulus (MPa); (B) UTS (MPa); (C) strain at fracture (percent). GA-b: GA-treated bovine; decell b: decellularized bovine; GA-p: GA-treated porcine; decell p: decellularized porcine; UTS: ultimate tensile strength.
