In order to improve the safety, durability, elasticity, biocompatibility, and clinical efficacy of tissue-engineered skin, several powerful seed cells have already found their application in wound repair, and a variety of bioactive scaffolds have been discovered to influence cell fate in epidermogenesis. These exuberant interests provide insights into advanced construction strategies for complex skin mimics. Based on these exciting developments, a complete full-thickness tissue-engineered skin is likely to be generated.展开更多
目的研究不同类型及不同浓度胶原蛋白构建的组织工程皮肤随着培养时间的增加皮肤收缩的情况。方法分别采用不同浓度牛肌腱胶原蛋白和鼠尾胶原蛋白构建组织工程皮肤,测量组织工程皮肤的收缩度,采用Wilcoxon Signed Ranks Test和Friedman ...目的研究不同类型及不同浓度胶原蛋白构建的组织工程皮肤随着培养时间的增加皮肤收缩的情况。方法分别采用不同浓度牛肌腱胶原蛋白和鼠尾胶原蛋白构建组织工程皮肤,测量组织工程皮肤的收缩度,采用Wilcoxon Signed Ranks Test和Friedman Test对结果进行分析。结果牛肌腱胶原蛋白构建的组织工程皮肤收缩度要小于鼠尾胶原蛋白构建的组织工程皮肤(P<0.01);不同浓度胶原蛋白构建的组织工程皮肤其收缩度也不相同(P<0.01)。组间比较差异有显著性(P<0.01)。结论牛肌腱胶原蛋白构建的组织工程皮肤在保持其形态稳定性上显著优于鼠尾胶原蛋白构建的组织工程皮肤。牛肌腱胶原构建的组织工程皮肤,胶原浓度越高其形态稳定性越好。展开更多
