Skeletal muscles in vertebrates are highly specialised tissues. Their development involves cell cycle withdrawal, cellular fusion, and differentiation into multinucleated muscle fibres. Most insights into trunk muscle development have been derived from studies on both anamniotic and amniotic model species, revealing numerous similarities across species. However, valuable perspectives on the evolutionary aspects of myogenesis have been obtained from research on non-model vertebrates. Despite variations in spatiotemporal gene expression and morphology, the goal is to develop multinucleated, fully functional trunk muscles.
