- Abstract
Musculoskeletal ageing and its associated diseases are major contributors to the loss of independence and reduced quality of life in older people. Several recent studies indicate that cellular senescence is a contributor to age-related loss of function in various organs including muscle, bones and joints. Importantly, these studies indicate that therapies targeting specifically senescent cells have great therapeutic potential in improving musculoskeletal health during ageing. Senescent cells are characterised by dramatic changes in mitochondrial function, metabolism and homeostasis. Mitochondrial dysfunction has been shown to contribute to senescence and the SASP. Here we review the role of cellular senescence in musculoskeletal ageing as well as the potential mechanisms by which mitochondrial dysfunction may impact on the induction and development of the senescent phenotype., (Copyright © 2018 Elsevier Inc.
