Abstract
Bone aging,a major global health concern,is the natural decline in bone mass and strength.Concurrently,extracellular vesicles(EVs),tiny membrane-bound particles produced by cells,have gained recognition for their roles in various physiological processes and age-related diseases.The interaction between EVs and bone aging is of growing interest,particularly their effects on bone metabolism,which become increasingly critical with advancing age.In this review,we explored the biology,types,and functions of EVs and emphasized their regulatory roles in bone aging.We examined the effects of EVs on bone metabolism and highlighted their potential as biomarkers for monitoring bone aging progression.Furthermore,we discussed the therapeutic applications of EVs,including targeted drug delivery and bone regeneration,and addressed the challenges associated with EV-based therapies,including the technical complexities and regulatory issues.We summarized the current research and clinical trials investigating the role of EVs in bone aging and suggested future research directions.These include the potential for personalized medicine using EVs and the integration of EV research with advanced technologies to enhance the management of age-related bone health.This analysis emphasized the transformative potential of EVs in understanding and managing bone aging,thereby marking a significant advancement in skeletal health research.
