Abstract

Skeletal muscle may be injured upon physical activity, or due to myofiber frailty caused by degenerative disorders. As a metabolic tissue, skeletal muscle has the innate ability of regeneration. Skeletal muscle regeneration may be endowed to the action of quiescent satellite cells, the resident muscle stem cells, and other interstitial and inflammatory cells that directly and indirectly contribute to adult myogenesis. However, the process of muscle regeneration greatly relies on intercellular communication through signaling factors such as proteins, microRNAs (miRNAs), inflammatory cytokines, and membrane lipids that must be tightly coordinated. It is becoming more evident that the release and transmission of these factors involve extracellular vesicles (EVs) liberated by myofibers and other cells in the milieu of the injured muscle. The cargo of EVs is responsible for altering the state of their target cells by delivering purposeful molecules such as messenger RNAs, miRNAs, lipids, and proteins or by aiming at the alteration of gene expression. These changes activate downstream pathways involved in tissue repair. Due to the heterogeneity of EVs with regard to their cargo, location, size, as well as timing of formation and release, the repair and regeneration of skeletal muscle may subsequently be impacted. This chapter focuses on the impact of EVs as biological cues directing stem cell differentiation and modulating the overall process of skeletal muscle regeneration.
