Attracting stem cells and facilitating bone regeneration by adhesive protein

From Pohang University, South Korea: “Here, a cell recognitive osteogenic barrier coating was proposed using a bioengineered mussel adhesive protein (MAP) fused with Alg–Gly–Asp (RGD) peptide to achieve highly accelerated bone regeneration. The fusion bioadhesive MAP-RGD exhibited outstanding performance as a bioactive physical barrier that enabled effective cell occlusion and a prolonged, localized delivery of bone morphogenetic protein-2 (BMP-2). The MAP-RGD@BMP-2 coating promoted in vitro cellular behaviors and osteogenic commitments of mesenchymal stem cells (MSCs) via the synergistic crosstalk effects of the RGD peptide and BMP-2 in a surface-bound manner.”     MORE
