From: Incidence and severity of myofiber branching with regeneration and aging
Illustration of the myofiber branching model. After muscle injury, satellite cells proliferate, differentiate and fuse either directly to the damaged myofiber or with each other to form myotubes. Subsequently, these myotubes may also fuse with the damaged area to repair the myofiber. A defect in adhesion or fusion during muscle regeneration may lead to branched myofibers.
