In recent years, plant based scaffold due to its inherent properties such as mechanical stability, renewability, easy mass production, inexpensiveness, biocompatibility and biodegradability with low toxic effects have received much attention in the field of bone tissue engineering. Design of good tissue compatible plant based polymer scaffold plays a vital role in biomedicine, nanomedicine and in various tissue engineering applications. The present study focused on the fabrication of a novel herbal scaffold using the medicinal plants Spinacia oleracea (SO) and Cissus quadrangularis (CQ) extracts incorporated with Alginate (Alg), Carboxy Methyl Cellulose (CMC) by lyophilization method. The structural nature and the properties of prepared scaffold were analyzed by XRD, FE-SEM, FTIR, EDAX, TGA, swelling ratio, porosity, in-vitro degradation and cell viability studies. The biocompatible nature of the plant based polymer scaffold was assessed using MG-63 Human Osteosarcoma cell line. The investigation of biocompatibility study showed that Alg/CMC/SO scaffold expressed higher cell viability than Alg/CMC/SO-CQ scaffold, which possess better cellular biocompatibility. The results of the present study suggested that plant based Alg/CMC/SO scaffold serve as a potential biopolymer scaffold which could be further exploited for bone tissue applications.
近年来,植物基支架由于其固有的机械稳定性、可再生性、易于大规模生产、廉价、生物相容性和可生物降解性以及低毒性等特性,在骨组织工程领域受到了广泛关注。设计良好的组织相容性植物基聚合物支架在生物医学、纳米医学和各种组织工程应用中起着至关重要的作用。本研究集中于使用药用植物菠菜(SO)和四方葡萄藤(CQ)提取物与藻酸盐(Alg)、羧甲基纤维素(CMC)通过冻干法制备新型草药支架。通过 XRD、FE-SEM、FTIR、EDAX、TGA、溶胀比、孔隙率、体外降解和细胞活力研究分析了制备支架的结构性质和性能。使用 MG-63 人骨肉瘤细胞系评估了植物基聚合物支架的生物相容性。生物相容性研究的结果表明,Alg/CMC/SO 支架的细胞活力高于 Alg/CMC/SO-CQ 支架,表明其具有更好的细胞生物相容性。本研究结果表明,植物基 Alg/CMC/SO 支架可作为一种有潜力的生物聚合物支架,可进一步用于骨组织应用。
