The engineering of skeletal muscle tissue has gained considerable attention in recent years because of its clinical applications, which include muscle replacement and treatment of muscle-related disease. Magnetic nanoparticle internalization by skeletal muscle cells has been proposed as a means of improving cell density. In this study, by embedding magnetic nanoparticles in mouse C2C12 myoblast cells to engineer a muscle tissue sheet, we evaluated the cellular uptake of magnetic nanoparticles and their effects on cell proliferation and differentiation. Our results show a tendency for decreased muscle fiber thickness in C2C12 cells with internalized magnetite nanoparticles. However, no change was found in the number of cells or differentiation.
