In either case, as far as I can tell, the process occurs in three main phases: proliferation, fusion, and polishing.  The proliferation phase aims to produce as many dividing satellite cells as possible, using the methods previously described and likely in a specialized medium containing morphogens that will allow for self-renewal of the satellite cells but not lineage commitment, possibly through the use of Wnt proteins such as Wnt7a [76]. Once enough cells are produced, the cells will be transferred to a separate apparatus in a new medium that will promote the production of myocytes and myocyte fusion into myotubes. Classically, this is done via serum starvation, however as I discuss below the use of serum-free components will be essential and thus alternative yet similar methods likely exist. The process of fusion may additionally be aided by nano-patterned plastics or other scaffolding materials, substrates, or biomaterials which will promote myotube maturation as well as provide tensile points of attachment.  Once mature myotubes are produced, they can be harvested and "polished" into a final product, likely through some method of compaction of the cells into a final shape and form. This entire process could likely take place within a month with a final product consisting of up to dozens of billions of cells starting from a few thousand.
