Extracellular matrices have drawn attention in tissue engineering as potential biomaterials for scaffold fabrication because of their bioactive components. Noninvasive techniques of scaffold fabrication and cross-linking treatments are believed to maintain the integrity of bioactive molecules while providing proper architectural and mechanical properties. Cartilage matrix derived scaffolds are designed to support the maintenance of chondrocytes and provide proper signals for differentiation of chondroinducible cells. Chondroinductive potential of bovine articular cartilage matrix derived porous scaffolds on human dermal fibroblasts and the effect of scaffold shrinkage on chondrogenesis were investigated. An increase in sulfated glycosaminoglycans production along with upregulation of chondrogenic genes confirmed that physically treated cartilage matrix derived scaffolds have chondrogenic potential on human dermal fibroblasts.
由于细胞外基质具有生物活性成分,因此在组织工程中作为用于制造支架的潜在生物材料受到了关注。支架制造和交联处理的非侵入性技术被认为在提供适当的结构和机械性能的同时,能够维持生物活性分子的完整性。源自软骨基质的支架旨在支持软骨细胞的维持,并为软骨诱导细胞的分化提供适当的信号。研究了源自牛关节软骨基质的多孔支架对人皮肤成纤维细胞的软骨诱导潜力以及支架收缩对软骨形成的影响。硫酸化糖胺聚糖产量的增加以及软骨生成基因的上调证实,经物理处理的源自软骨基质的支架对人皮肤成纤维细胞具有软骨生成潜力。
