Synergistic effect of bimodal pore distribution and artificial extracellular matrices in polymeric scaffolds on osteogenic differentiation of human mesenchymal stem cells.

The main objective of this study was to enhance the biological performance of resorbable polymeric scaffolds for bone tissue engineering. Specifically, we focused on both microstructure and surface modification of the scaffolds to augment adhesion, proliferation and osteogenic differentiation of human mesenchymal stem cells (hMSC). Moreover, a new cell seeding method assuring 90% seeding efficiency on the scaffolds was developed.
