Tissue regeneration is thought to have considerable promise with the use of scaffolds designed for tissue engineering. Although polymer-based scaffolds for tissue engineering have been used extensively and developed quickly, their ability to mimic the in-vivo milieu, overcome immunogenicity, and have comparable mechanical or biochemical properties has limited their capability for repair. Fortunately, there is a compelling method to get around these challenges thanks to the development of extracellular matrix (ECM) scaffolds made from decellularized tissues. We used ECM decellularized sheep kidney capsule tissue in our research. Using detergents such as Triton-X100 and sodium dodecyl sulfate (SDS), these scaffolds were decellularized. DNA content, histology, mechanical properties analysis, attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR), biocompatibility, hemocompatibility and scanning electron microscope (SEM) imaging were measured. The results showed that the three-dimensional (3D) structure of the ECM remained largely intact. The scaffolds mentioned above had several hydrophilic properties. The best biocompatibility and blood compatibility properties were reported in the SDS method of 0.5%. The best decellularization scaffold was introduced with 0.5% SDS. Therefore, it can be proposed as a scaffold that has ECM like natural tissue, for tissue engineering applications.
组织再生被认为具有很大的潜力,可以使用专门设计用于组织工程的支架。尽管聚合物基支架已被广泛用于组织工程,并得到了快速发展,但它们在模拟体内环境、克服免疫原性以及具有相当的机械或生化性能方面的能力,限制了它们的修复能力。幸运的是,由于从去细胞化组织中开发出细胞外基质 (ECM) 支架,有一个非常有吸引力的方法可以克服这些挑战。我们在研究中使用了 ECM 去细胞化的绵羊肾囊组织。使用 Triton-X100 和十二烷基硫酸钠 (SDS) 等去污剂对这些支架进行去细胞化处理。测量了 DNA 含量、组织学、力学性能分析、衰减全反射傅里叶变换红外光谱 (ATR-FTIR)、生物相容性、血液相容性和扫描电子显微镜 (SEM) 成像。结果表明,ECM 的三维 (3D) 结构基本保持完整。上述支架具有几种亲水性能。在 0.5% SDS 方法中报告了最佳的生物相容性和血液相容性。最佳的去细胞化支架是在 0.5% SDS 下引入的。因此,可以提出 ECM 类似于天然组织的支架,用于组织工程应用。
