6. METHODS: Four collagen scaffolds were investigated in-situ in an ovine model after 8 weeks of omental implantation to assess their suitability with regards to integration and cellular infiltration for esophagus organ tissue engineering: (a) Acellular bovine pericardial collagen (BPC), (b) Acellular cross-linked (HDMI hexamethylene diisocyanate) porcine dermal collagen (PDC), (c) Porcine porous collagen (PPC) and (d) Bovine tendon dual-layered (type-1) collagen (DLC).
