Deferoxamine immobilized poly(D,L-lactide) membrane via polydopamine adhesive coating: The influence on mouse embryo osteoblast precursor cells and human umbilical vein endothelial cells

Osteogenesis and angiogenesis play the prominent role in the bone regeneration. In this study, deferoxamine (DFO), an induced agent for osteogenesis and angiogenesis, was modified onto the surface of poly(D,L-lactide) (PDLLA) membrane via a facile and convenient approach based on the self-polymerization of dopamine (DOPA). The surface composition, morphology, hydrophilicity and surface energy of the original and modified PDLLA membranes were...
