Seeding of SIS scaffolds with autologous USCs. a Collagen-based scaffolds derived from porcine SIS were mechanically and chemically treated to remove cells. H&E (b) and DAPI (c) staining showed that there were two to four layers of USCs attached to both sides of the 5% PAA-treated SIS scaffold after seeding. Scale bar = 200 μm
