Muscle fibers are cylindrical cells that can contain hundreds of nuclei called myonuclei. On the periphery of these muscle fibers, stem cells, known as satellite cells, lay dormant in a quiescent state during resting conditions. With exercise, these cells can activate, often proliferate and may fuse to muscle fibers. Historically, this fusion of satellite cells has been thought to be to mediate the repair of focal damage to the muscle fiber. Additionally, it has been suggested that a myonucleus, which serves as a control center, can oversee only a finite jurisdiction – called the myonuclear domain. Therefore some researchers have speculated that satellite cells could supply additional nuclei to the muscle fiber during hypertrophy to keep up with the increasing domain. Interestingly, there is a recently growing body of evidence suggesting several non-fusion-related roles satellite cells can play. – Today, Dr. Kevin Murach is here to give us some insight into the interplay of satellite cells and muscle growth! . . . _______________________ Dr. Murach received a Ph.D. in Human Bioenergetics from Ball State University in 2015 and post-doctoral training in muscle stem cell biology at the University of Kentucky Center for Muscle Biology. His research broadly pertains to adult skeletal muscle mass regulation in the context of exercise, aging, and beyond. Currently, he is positioned as an Assistant Professor at the University of Arkansas and serves as the principal investigator/project leader in the Molecular Muscle Mass Regulation Laboratory.  Kevin's Google Scholar: https://scholar.google.com/citations?user=45UuplEAAAAJ&hl=en Kevin’s ResearchGate: https://www.researchgate.net/profile/Kevin-Murach Kevin's Twitter: https://twitter.com/KevinMurachPhD Kevin's Instagram: https://www.instagram.com/kevinmurachphd/ . . . . .
