In this review, we seek a novel strategy for establishing a rejuvenating microenvironment through senescent cells specific reprogramming. We suggest that partial reprogramming can produce a secretory phenotype that facilitates cellular rejuvenation. This strategy is desired for specific partial reprogramming under control to avoid tumour risk and organ failure due to loss of cellular identity. It also alleviates the chronic inflammatory state associated with ageing and secondary senescence in adjacent cells by improving the senescence-associated secretory phenotype. This manuscript also hopes to explore whether intervening in cellular senescence can improve ageing and promote damage repair, in general, to increase people's healthy lifespan and reduce frailty. Feasible and safe clinical translational protocols are critical in rejuvenation by controlled reprogramming advances. This review discusses the limitations and controversies of these advances' application (while organizing the manuscript according to potential clinical translation schemes) to explore directions and hypotheses that have translational value for subsequent research.
在这篇综述中,我们寻求通过衰老细胞特异性重编程建立一种新颖的年轻化微环境的策略。我们认为部分重编程可以产生一种有利于细胞年轻化的分泌表型。这种策略需要在控制下进行特定的部分重编程,以避免因细胞身份丧失而导致肿瘤风险和器官衰竭。它还通过改善与衰老相关的分泌表型,减轻与年龄相关的慢性炎症状态和邻近细胞的继发性衰老。本文还希望探讨干预细胞衰老是否可以改善衰老并促进损伤修复,从而总体上增加人们的健康寿命并减少虚弱。通过控制重编程进展来实现年轻化,可行且安全的临床转化方案至关重要。本综述讨论了这些进展应用的局限性和争议(同时根据潜在的临床转化方案组织手稿),以探索具有后续研究转化价值的方向和假设。
