To date, a completely in vitro repopulated tissue-engineered heart valve has not been developed. This study focused on sequentially seeding 2 cell populations onto porcine decellularized heart valve leaflets (HVL) and pericardia (PER) to obtain fully

To date an optimal decellularization protocol of heart valve leaflets (HVL) and pericardia (PER) with an adequate preservation of the extracellular matrix (ECM) is still lacking. This study compares a 4 day Triton X-100-based protocol with faster SDC

Freshly excised porcine aortic heart valve cusps were subjected to a uni-axial flexural indentation test, from which the rupture characteristics and a functional stiffness parameter were determined. It was found that the flexural mechanical propertie

OBJECTIVES: Xenogenic extracellular heart valve matrices have been suggested as scaffolds for tissue engineering. However, these matrices are immunogenic and stimulate an intense cell-mediated immune response and calcification. Mitigating the immunog
