Effect of bovine pericardial extracellular matrix scaffold niche on seeded human mesenchymal stem cell function.

ABSTRACT: Numerous studies have focused on generation of unfixed bovine pericardium (BP) extracellular matrix (ECM) for clinical application. However, the extent to which maintenance of native ECM niche is capable of directing behavior of repopulating cells remains relatively unexplored. By exploiting the sidedness of BP scaffolds (i.e., serous or fibrous surface), this study aims to determine the effect of ECM niche preservation on cellular repopulation using different scaffold generation methods. BP underwent either sodium dodecyl sulfate (SDS) decellularization or stepwise, solubilization-based antigen removal using amidosulfobetaine-14 (ASB-14). SDS scaffolds were toxic to repopulating human mesenchymal stem cells (hMSC). Scanning electron microscopy revealed distinct surface ultrastructure of A
