  "summary": "Throughout life, somatic cells must preserve their identity while retaining the capacity to adapt. How this balance shifts with ageing and rejuvenation remains unclear. Here we identify miR-29 as a central point of convergence between the transcriptional programmes of physiological ageing and two routes to rejuvenation: induced reprogramming and the natural reset of early development. miR-29…",
