在这项研究中,我们详细介绍了植物基生物材料的脱细胞、物理表征、成像和 体内 植入方法,以及支架中细胞接种和分化的方法。所描述的方法允许评估用于骨组织工程应用的植物基生物材料。

研究范围的重点是评估苹果衍生的纤维素支架在骨组织工程中的潜力,并评估其在体外和体内的机械性能。所讨论的问题包括支架的成骨潜力、它们支持细胞侵袭、矿化的能力以及它们的机械性能。该研究领域的最新进展涉及利用来自各种植物的纤维素基支架进行组织重建。

这些支架可以被塑造和修改,以实现所需的特性,并且已经采用了功能化技术来增强其有效性。该协议解决的研究差距是对用于骨组织工程的苹果衍生纤维素的机械性能的有限研究。虽然以前的研究已经探索了支架的潜在应用,但其机械特性尚未得到广泛研究。

本研究通过评估支架的机械性能来填补这一空白,强调它们与健康骨组织相比的局限性,并强调需要进一步开发以优化其性能。这项研究的结果证实了来自苹果的纤维素支架具有促进成骨细胞前细胞粘附、成骨细胞分化和增殖的潜力,从而促进了该领域的研究进展。在研究之后,人们可以提出一些问题,例如,如何优化来自植物的纤维素支架的机械性能,以密切匹配或模仿天然骨组织的机械性能?

可以采用化学改性或复合策略来增强植物来源的纤维素支架的刚度和承载能力,用于骨组织工程应用。
