摘要:

文题释义:
数字光处理3D打印:是生物3D打印系统之一,通过光聚合以逐层方式制造水凝胶支架,具有高分辨率和打印速度快速等优点。
透明质酸:是一种酸性黏多糖,以独特的分子结构和理化性质在机体内显示出多种重要的生理功能,如润滑关节、调节血管壁通透性、调节蛋白质、水电解质扩散及运转、促进创伤愈合等。

背景:组织工程技术在组织与器官的修复治疗中展现出广阔的应用前景,也为处理大面积皮肤损伤提供了一种创新解决方案。然而,鉴于皮肤结构的复杂性,创建具备功能性的三维皮肤组织工程模型以模拟或替代自然皮肤仍然面临诸多挑战。
目的:开发一种成分仿生的甲基丙烯酰化透明质酸/脱细胞皮肤水凝胶支架,评估该支架对人脐静脉内皮细胞增殖、活性、迁移与成管的影响。
方法:利用数字光处理3D打印技术分别制备甲基丙烯酰化透明质酸水凝胶支架和甲基丙烯酰化透明质酸/脱细胞皮肤基质水凝胶支架,扫描电镜下观察两种支架的微观形貌,通过Tranwell小室、划痕实验检测两种支架对人脐静脉内皮细胞迁移的影响,小管形成实验检测两种支架对人脐静脉内皮细胞成管的影响。使用两种支架的前驱液分别重悬人脐静脉内皮细胞,利用数字光处理3D打印技术分别制备含人脐静脉内皮细胞的甲基丙烯酰化透明质酸水凝胶支架和甲基丙烯酰化透明质酸/脱细胞皮肤基质水凝胶支架,通过CCK-8实验、死活染色、鬼笔环肽染色检测两种支架内人脐静脉内皮细胞的增殖、活性与状态。
结果与结论:①扫描电镜下可见两种支架均呈现三维立体的多孔结构,孔与孔之间相互贯通;两种支架均可促进人脐静脉内皮细胞的迁移与成管,并且甲基丙烯酰化透明质酸/脱细胞皮肤基质水凝胶支架的促进作用强于甲基丙烯酰化透明质酸水凝胶支架;②CCK-8实验结果显示,两种支架均可促进人脐静脉内皮细胞的增殖,并且甲基丙烯酰化透明质酸/脱细胞皮肤基质水凝胶支架内的细胞增殖更快;死活染色显示,两种水凝胶支架内的人脐静脉内皮细胞均呈均匀且立体分布状态,并且均具有较高的存活率;鬼笔环肽染色显示,人脐静脉内皮细胞在两种支架内均呈现良好的伸展状态,并且甲基丙烯酰化透明质酸/脱细胞皮肤基质水凝胶支架内的细胞伸展更加充分;③结果表明,甲基丙烯酰化透明质酸/脱细胞皮肤水凝胶支架可促进人脐静脉内皮细胞的增殖、迁移与成管,具有良好的细胞相容性。

Abstract: BACKGROUND: Tissue engineering technology holds broad application prospects in the repair and treatment of tissues and organs, offering a novel solution for the treatment of large-scale skin defects. However, due to the complexity of skin structure, constructing functional three-dimensional skin tissue engineering models to mimic or replace natural skin remains challenging.
OBJECTIVE: To develop a bio-mimetic methyl acrylated hyaluronic acid/decellularized skin hydrogel scaffold and evaluate its effects on the proliferation, activity, migration and tube formation of human umbilical vein endothelial cells. 
METHODS: Digital light processing 3D printing technology was utilized to produce methyl acrylated hyaluronic acid hydrogel scaffolds and methyl acrylated hyaluronic acid/decellularized skin matrix hydrogel scaffolds. The microscopic morphology of the two scaffolds was observed under a scanning electron microscope. The effects of the two scaffolds on the migration of human umbilical vein endothelial cells were detected by Tranwell chamber and scratch test. The effect of the two scaffolds on the tube formation of human umbilical vein endothelial cells was detected by the tube formation experiment. The human umbilical vein endothelial cells were resuspended in the precursor solution of the two scaffolds. The methyl acrylated hyaluronic acid hydrogel scaffold containing human umbilical vein endothelial cells and the methyl acrylated hyaluronic acid/decellularized skin matrix hydrogel scaffold were prepared by digital light processing 3D printing technology. The proliferation, activity, and state of human umbilical vein endothelial cells in the two scaffolds were detected by CCK-8 assay, live/dead staining, and phalloidin staining.
RESULTS AND CONCLUSION: (1) Scanning electron microscopy showed that both scaffolds presented a three-dimensional porous structure with interconnected pores; both scaffolds could promote the migration and tube formation of human umbilical vein endothelial cells, and the promoting effect of methyl acrylated hyaluronic acid/decellularized skin matrix hydrogel scaffold was stronger than that of methyl acrylated hyaluronic acid hydrogel scaffold. (2) CCK-8 assay results showed that both scaffolds could promote the proliferation of human umbilical vein endothelial cells, and the proliferation of cells in methyl acrylated hyaluronic acid/decellularized skin matrix hydrogel scaffold was faster. Live/dead staining showed that the human umbilical vein endothelial cells in both hydrogel scaffolds were uniformly and three-dimensionally distributed, and both had a high survival rate. Phalloidin staining showed that the human umbilical vein endothelial cells in both scaffolds showed a good extension state and the cells in the methyl acrylated hyaluronic acid/decellularized skin matrix hydrogel scaffold were more fully extended. (3) The results showed that the methyl acrylated hyaluronic acid/decellularized skin hydrogel scaffold could promote the proliferation, migration, and tube formation of human umbilical vein endothelial cells and had good cell compatibility.
