This study is significant because it demonstrates an attempt to design a scaffold specifically for small intestine using a novel fabrication method, resulting in an architecture that resembles intestinal villi. In addition, we use the versatile polymer poly(glycerol sebacate) (PGS) for artificial intestine, which has tunable mechanical and degradation properties that can be harnessed for further fine-tuning of scaffold design. Moreover, the utilization of PGS allows for future development of growth factor and drug delivery from the scaffolds to promote artificial intestine formation.
这项研究意义重大,因为它展示了一种尝试,即使用新颖的制造方法专门为小肠设计支架,从而产生类似于肠绒毛的结构。此外,我们使用多功能聚合物聚(癸二酸甘油酯)(PGS)来制造人工肠,它具有可调节的机械和降解性能,可以进一步精细调整支架设计。此外,PGS 的利用允许从支架中释放生长因子和药物以促进人工肠形成,从而实现未来的发展。
