Electrospun scaffold characterization. Scanning electron microscope (SEM) imaging of the graft wall at (A) 100×, (B) 500×, and (C) 4000× demonstrating the microstructural characteristics of the electrospun scaffold. Sub-1 μm diameter polymeric fibers (average 882 ± 226 nm) overlap to form a porous tubular conduit. SEM images of the scaffold in cross-section at (D) 100× and (E) 400× highlight the wall thickness (average 234.8 ± 20.3 μm), three-dimensional porosity, and luminal diameter (average 526.4 ± 22.6 μm) of the graft. A gross image (F) of the TEVG prior to implantation demonstrates the scale of the murine graft. (G) Pore size distribution based on measurements of maximum and minimum Feret diameters.
