Possible biofabrication methods to develop hollow, tubular scaffolds to replace/repair tubular organs.
(1) Solvent evaporation of polycaprolactone; (2) magnified cross section of (1);74 (3) magnified cross section of solvent exchanged polycaprolactone-based scaffold;74 (4) decellularised tracheal segment;75 (5) 3D-printed tubular tissue;76 (6) hybrid scaffold (polyurethane outer coat on a decellularised oesophagus); (7) electrospun tubular tissue.77 Figure of structures of natural tubular organs is adapted from Basu and Ludlow.78
