Biomaterials derived from extracellular matrices (ECMs) were extensively used for skin tissue engineering and wound healing. ECM is a complex network of biomolecules (e.g., proteins), which provide organizational support to cells for growth. Thus, ECM could be an ideal biomaterial for fabricating the scaffold. However, oxidative stress and biofilm formation at the wound site remains a major challenge that could be neutralized using herbal ingredients (e.g., curcumin). In this study, ECM was extracted from the biowaste of the goat abattoir by using decellularization. The goat small intestine submucosa (G-SIS) is decellularized to obtain the decellularized G-SIS (DG-SIS) and curcumin (in different concentrations) was incorporated in the DG-SIS to fabricate curcumin-embedded DG-SIS scaffolds. Changes brought by increasing the concentrations of the curcumin in DG-SIS were observed in various properties, including free radical scavenging and antibacterial properties. Results depicted that the scaffolds are porous, biodegradable, biocompatible, antibacterial, and hydrophilic and showed sustained release of curcumin. Besides, it showed free radicals scavenging property. The porosity and hydrophilicity of the scaffolds were decreased with an increase in the curcumin content. However, biodegradability, free radical scavenging, biocompatibility, and antibacterial properties of the scaffolds increased with an increase in the curcumin content. The DG-SIS scaffold containing 1 wt % of curcumin may be a potential biomaterial for wound-healing and skin tissue engineering.

脱细胞山羊小肠黏膜下层姜黄素用于伤口愈合和皮肤组织工程

源自细胞外基质 (ECM) 的生物材料被广泛用于皮肤组织工程和伤口愈合。ECM 是一个复杂的生物分子(例如蛋白质)网络,为细胞的生长提供组织支持。因此,ECM 可能是制造支架的理想生物材料。然而,伤口部位的氧化应激和生物膜形成仍然是可以使用草药成分(例如姜黄素)中和的主要挑战。在这项研究中,通过去细胞化从山羊屠宰场的生物废物中提取了 ECM。将山羊小肠黏膜下层 (G-SIS) 脱细胞以获得脱细胞 G-SIS (DG-SIS) 并将姜黄素 (不同浓度) 掺入 DG-SIS 以制造姜黄素包埋的 DG-SIS 支架。增加 DG-SIS 中姜黄素浓度带来的变化在各种特性中都可以观察到,包括自由基清除和抗菌特性。结果表明,支架是多孔的、可生物降解的、生物相容的、抗菌的和亲水的,并显示出姜黄素的持续释放。此外,它还表现出清除自由基的特性。支架的孔隙率和亲水性随着姜黄素含量的增加而降低。然而,随着姜黄素含量的增加,支架的生物降解性、自由基清除性、生物相容性和抗菌性能也随之提高。含有 1 wt% 姜黄素的 DG-SIS 支架可能是用于伤口愈合和皮肤组织工程的潜在生物材料。包括清除自由基和抗菌性能。结果表明,支架是多孔的、可生物降解的、生物相容的、抗菌的和亲水的,并显示出姜黄素的持续释放。此外,它还表现出清除自由基的特性。支架的孔隙率和亲水性随着姜黄素含量的增加而降低。然而,随着姜黄素含量的增加,支架的生物降解性、自由基清除性、生物相容性和抗菌性能也随之提高。含有 1 wt% 姜黄素的 DG-SIS 支架可能是用于伤口愈合和皮肤组织工程的潜在生物材料。包括清除自由基和抗菌性能。结果表明,支架是多孔的、可生物降解的、生物相容的、抗菌的和亲水的,并显示出姜黄素的持续释放。此外,它还表现出清除自由基的特性。支架的孔隙率和亲水性随着姜黄素含量的增加而降低。然而,随着姜黄素含量的增加,支架的生物降解性、自由基清除性、生物相容性和抗菌性能也随之提高。含有 1 wt% 姜黄素的 DG-SIS 支架可能是用于伤口愈合和皮肤组织工程的潜在生物材料。并且亲水并且显示姜黄素的持续释放。此外,它还表现出清除自由基的特性。支架的孔隙率和亲水性随着姜黄素含量的增加而降低。然而,随着姜黄素含量的增加,支架的生物降解性、自由基清除性、生物相容性和抗菌性能也随之提高。含有 1 wt% 姜黄素的 DG-SIS 支架可能是用于伤口愈合和皮肤组织工程的潜在生物材料。并且亲水并且显示姜黄素的持续释放。此外,它还表现出清除自由基的特性。支架的孔隙率和亲水性随着姜黄素含量的增加而降低。然而,随着姜黄素含量的增加,支架的生物降解性、自由基清除性、生物相容性和抗菌性能也随之提高。含有 1 wt% 姜黄素的 DG-SIS 支架可能是用于伤口愈合和皮肤组织工程的潜在生物材料。
