Research in creating 3D structures mirroring the extracellular matrix (ECM) with accurate environmental cues holds paramount significance in biological applications.Biomaterials that replicate ECM properties-mechanical, physicochemical, and biological-emerge as pivotal tools in mimicking ECM behavior.Incorporating synthetic and natural biomaterials is widely used to produce scaffolds suitable for the intended organs.Polycaprolactone (PCL), a synthetic biomaterial, boasts commendable mechanical properties, albeit with relatively modest biological attributes due to its hydrophobic nature.Chitosan (CTS) exhibits strong biological traits but lacks mechanical resilience for complex tissue regeneration.Notably, both PCL and CTS have demonstrated their application in tissue engineering for diverse types of tissues.Their combination across varying PCL:CTS ratios has increased the likelihood of fabricating scaffolds to address defects in sturdy and pliable tissues.This comprehensive analysis aspires to accentuate their distinct attributes within tissue engineering across different organs.The central focus resides in the role of PCL:CTS-based scaffolds, elucidating their contribution to the evolution of advanced functional 3D frameworks tailored for tissue engineering across diverse organs.Moreover, this discourse delves into the considerations pertinent to each organ.
在生物应用中,用具有准确环境线索的 3D 结构来模拟细胞外基质(ECM)的研究具有至关重要的意义。复制 ECM 特性(机械、物理化学和生物学)的生物材料成为模拟 ECM 行为的重要工具。合成和天然生物材料的结合广泛用于生产适合预期器官的支架。聚己内酯(PCL)是一种合成生物材料,具有令人称道的机械性能,但由于其疏水性,生物属性相对较低。壳聚糖(CTS)具有很强的生物学特性,但缺乏用于复杂组织再生的机械弹性。值得注意的是,PCL 和 CTS 都已在不同类型组织的组织工程中得到了应用。它们在不同的 PCL:CTS 比例下的结合增加了制造支架以解决坚固和柔韧组织缺陷的可能性。这项全面分析旨在强调它们在不同器官的组织工程中的独特属性。中心重点在于基于 PCL:CTS 的支架的作用,阐明它们对为不同器官的组织工程定制的先进功能 3D 框架的发展的贡献。此外,本文还探讨了与每个器官相关的注意事项。
