The discovery of a potent photosensitizer with desirable immunogenic cell death (ICD) ability can prominently enhance antitumor immunity in photodynamic therapy (PDT). However, majority commercially-available photosensitizers suffer from serious aggregation and fail to elicit sufficient ICD. Pyroptosis as newly identified pattern for ICD generation is rarely disclosed reported photosensitizers. In addition, the excellent mitochondria-anchored evokes prominent mitochondria oxidative stress,...

摘要: 甲基丙烯酸酐明胶(Methacrylated gelatin,GelMA)是具有光敏官能团的改性明胶,有良好的生物相容性,广泛用于构建皮肤、神经等软组织支架。然而,光照交联单一成分的GelMA,其力学性能和结构维持性较差,难以通过挤出3D打印成形生物支架。提出一种适用于挤出式打印且力学性能增强的GelMA复合凝胶,其主要成分为GelMA、明胶和海藻酸钠。黏度测试试验筛选出适合挤出3D打印的复合材料配比,3D打印工艺试验研究和分析了打印气压、喷头移动速度、喷头高度、光照条件对挤出连续性和微丝直径的影响。当喷头内径为200 μm时,GelMA复合凝胶实现顺畅出丝(φ293~1 211 μm)的条件为气压在0.05~0.25 MPa,打印速度为1~15 mm/s,喷头高度为200~600 μm,光照强度为70~272.56 mW/cm2。拉伸试验表明光照交联后,复合凝胶较之同浓度GelMA(5%,w/v)的弹性模量提高近1倍,伸长率保持一致。细胞培养试验显示GelMA复合凝胶具有良好的生物相容性,包埋在其内部的人真皮成纤维细胞培养至第7天时存活率达85%。
