How can the SkMC be differentiated? Can you send me a protocol?
To differentiate the SkMC into myotubes, we recommend to use cells that have undergone a maximum of 4-5 population doublings. For this, the cells (ideally in P2 or P3) are cultured to 60-80% confluency in Skeletal Muscle Cell Growth Medium (C-23060). Then, a change to (serum-free) Differentiation Medium (C-23061) is performed to induce the differentiation process (formation of multinucleated syncytia). After 5 days, switch back to the Skeletal Muscle Cell Growth Medium for another 8 days to complete the differentiation. This protocol leads to stable myotubes and some of the myotubes show spontaneous contractions.
