To accelerate the vascularization of engineered tissue, an endothelial-specific fusion protein (VEGF-Fc), which consists of a human vascular endothelial growth factor (VEGF) and an immunoglobulin G Fc region, was fabricated and used to construct a bioactive interface in a porous scaffold. In this study, VEGF-Fc was immobilized on polycarprolactone (PCL) porous scaffolds by steeping, which is mediated by the hydrophobic binding of the Fc domain. The VEGF-Fc proteins were distributed stably and uniformly throughout the PCL porous scaffolds without affecting their surface morphology and mechanical properties. The immobilized VEGF-Fc activated the phosphorylation of VEGF2 receptor continuously, and further promoted... More
