概括

在前交叉带 (ACL) 移植中施加支架诱导的压缩,以ACL衍生细胞播种,可以提高细胞存活率并促进I型原蛋白的产生,改善移植的愈合. 这表明机械传导在带重建中起着关键作用.

科学领域:

生物医学工程生物医学工程
整形外科手术整形外科手术
再生医学是一种再生医学.

背景情况:

前十字带 (ACL) 重建通常使用肌移植,它用较弱的纤维性痕组织 (III型原蛋白) 而不是本地ACL组织来愈合.
这导致机械强度降低,与健康的ACL相比.

研究的目的:

调查脚手架诱导的压缩是否可以提高ACL衍生的细胞在肌移植中的生存和集成.
为了确定机械力量是否可以促进一个更像本地ACL移植的愈合环境.

主要方法:

从ACL衍生的细胞被重新播种到肌移植上.
一个纳米纤维聚烯酸乙烯 (PCL) 支架被用于对细胞移植结构施加压缩.
分析了原类型的基因表达和YAP转位in vitro.

主要成果:

与非压缩对照组相比,压缩细胞移植结构显著改善了细胞存活和融合.
在压缩组中观察到更高的I型原蛋白基因表达水平.
对YES相关蛋白 (YAP) 转移到核中与I型原蛋白表达增加相关.

结论:

脚手架诱导的压缩是一种有前途的方法,可以提高ACL肌移植的愈合.
由YAP介导的机械传导似乎在促进I型原蛋白合成和改善移植质量方面发挥着至关重要的作用.
这种方法可以导致更强大,更持久的ACL重建.

Clinical Applications of Epidermal Stem Cells

Clinical Applications of Epidermal Stem Cells

Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own EpiSCs...
