Esophageal tissue engineering is a promising approach to create an esophageal substitute after surgical resection of a part of the organ. Regeneration of esophageal tissue may be achieved using some synthetic or biological scaffolds. In the present study, scaffolds are obtained through the decellularization of porcine esophagi. In view of future implantation, it is important to test the mechanical properties of the decellularized matrices and to compare them with the data obtained for native pig esophagi. Results of longitudinal and circumferential traction experiments as well as inflation and burst tests are presented. The results obtained for the compliance of porcine decellularized matrices are novel. It is concluded that the decellularized matrices are suitable for use as esophageal substitutes.
食管组织工程是一种在部分器官手术切除后创建食管替代物的有前景的方法。使用一些合成或生物支架可以实现食管组织的再生。在本研究中,通过对猪食管进行去细胞处理获得支架。考虑到未来的植入,测试去细胞化基质的力学性能并将其与天然猪食管获得的数据进行比较很重要。本文展示了纵向和周向牵引实验以及膨胀和爆破试验的结果。猪去细胞化基质顺应性的研究结果是新颖的。得出的结论是,去细胞化基质适合用作食管替代物。
