Human SMCs are cultured on the PGA scaffolds (A) to produce the vascular grafts (B), which are then decellularized (C) and stored until the time of patient need. The acellular human-based vascular grafts may be directly implanted without ECs if the diameters are greater than 6 mm (D), or may be seeded with ECs from the patient for small-diameter (3 to 4 mm) applications.
