Aging is accompanied by the functional decline of cells, tissues, and organs, as well as a striking increase in a wide range of diseases. The reprogramming of somatic cells to induced pluripotent stem cells (iPSCs) opens new avenues for the aging field and has important applications for therapeutic treatments of age-related diseases. Here we review emerging studies on how aging and age-related pathways influence iPSC generation and property. We discuss the exciting possibility that reverting to a pluripotent stem cell stage erases several deficits associated with aging and offers new strategies for rejuvenation. Finally, we argue that reprogramming provides a unique opportunity to model aging and perhaps exceptional longevity.
衰老是伴随着细胞、组织和器官功能的下降,以及广泛的疾病显著增加的。体细胞重编程为诱导多能干细胞(iPSCs)为衰老领域开辟了新的途径,并为治疗与年龄相关的疾病提供了重要的应用。在这里,我们回顾了关于衰老和与年龄相关的途径如何影响 iPSC 生成和特性的新兴研究。我们讨论了这样一种令人兴奋的可能性,即回到多能干细胞阶段可以消除与衰老相关的几个缺陷,并为 rejuvenation 提供新的策略。最后,我们认为重编程为模型提供了一个独特的机会衰老,也许是异常的长寿。
