Co-electrospun blends of PU and PEG as potential biocompatible scaffolds for small-diameter vascular tissue engineering

► We develop small-diameter vascular grafts made of PU and PEG by electrospinning. ► The hybrid scaffolds could suppress the platelet adhesion. ► The hybrid scaffolds could support HUVECs attachment and proliferation. ► The hybrid scaffold was potential candidates for tissue engineering blood vessel.
