Summary

本手稿描述了一个两步方案,通过游离体重编程为人诱导的多能干细胞 (hiPSC) 并随后分化为足细胞 ,从 真皮成纤维细胞生成患者特异性足细胞。

Transcript

我们描述了一种通过将游离体真皮成纤维细胞重编程为人诱导的多能干细胞来产生人类足细胞的方案。这些细胞在足细胞食物过程和足细胞特异性标志物的表达方面比永生化的足细胞更类似于体内足细胞。足细胞是终末分化的细胞。

因此,这些细胞不再增殖,细胞培养中的原代足细胞分析受到限制。尽管通过使用有条件永生化的足细胞克服了细胞数量有限的问题,但这些足细胞呈现出去分化的表型和行为,这质疑它们在基础研究中的使用。在诱导多能干细胞的帮助下,足细胞可以在体外产生几乎无限的细胞数量,具有典型的足细胞形态,包括不同的食物过程和足细胞特异性标志物的表达。

当使用患者特异性干细胞分化成足细胞时,可以离体研究细胞的疾病特异性改变。如果,最初的皮肤活检是从患有遗传性足细胞疾病的患者身上进行的。用我们的方案生成的足细胞是携带患者突变的个性化病变细胞。

因此,这些细胞代表了一种改进的离体模型,以个体化的方法研究足细胞疾病和潜在的治疗物质。
