Cytotechnology:Wharton果冻间充质基质细胞的醛脱氢酶活性

2019-01-26 MedSci MedSci原创

间充质基质细胞(MSCs)是再生医学和靶向治疗中有前途的工具。尽管已经描述了不同的来源,但是仍然需要找到具有精确治疗功能的具有特定MSC亚群的有价值的来源。在这里,我们通过荧光激活细胞分选技术,两个沃顿的果冻(WJ)-MSCs群体基于其醛脱氢酶(ALDH)活性分离。因此观察到两种不同的ALDH活性(低与高)。然后我们分析了它们的基因表达谱,包括干性,表型,对缺氧的反应,血管生成,造血支持,免疫调节

间充质基质细胞(MSCs)是再生医学和靶向治疗中有前途的工具。尽管已经描述了不同的来源,但是仍然需要找到具有精确治疗功能的具有特定MSC亚群的有价值的来源。

在这里,我们通过荧光激活细胞分选技术,两个沃顿的果冻(WJ)-MSCs群体基于其醛脱氢酶(ALDH)活性分离。因此观察到两种不同的ALDH活性(低与高)。然后我们分析了它们的基因表达谱,包括干性,表型,对缺氧的反应,血管生成,造血支持,免疫调节和多向分化能力(成骨,脂肪生成和软骨形成)。根据ALDH活性,注意到这些群体的mRNA表达的许多差异。

总之,我们提供证据表明WJ具有两个不同的具有不同ALDH活性的MSC群。这些人群似乎显示出特定的功能能力,这对于简化治疗应用可能是有意义的。
