This protocol describes a cell culture model to study the differentiation of fetal rat skeletal muscle cells. The model uses serum-free medium, a nonbiological substrate N-1[3(trimethoxysilyl)propyl] diethylenetriamine (DETA) and fabricated microcantilevers to promote the differentiation of dissociated rat myocytes into robust myotubes. In this protocol, we also describe how to characterize the myotubes on the basis of morphology, immunocytochemistry and electrophysiology. Here, four major techniques are employed: fabrication of cantilevers, surface modification of the glass and cantilever substrates with a DETA SAM, a serum-free medium and refined culture techniques. This culture system has potential applications in biocompatibility studies, bioartificial muscle engineering, skeletal muscle differentiation studies and for better understanding of myopathies and neuromuscular disorders. The model can be established in 26-33 d.
