 And then, of course, we have to feed the cells something. So we put them in a liquid medium that provides all the nutrients that these cells need to grow and divide. Lastly, the cells on the scaffold, in the medium, all grow within a bioreactor, which is kind of like a large stainless steel tank, looks a lot like brewing equipment and can be just as big as well. And the bioreactor really just provides that constant, stable environment that those cells need to flourish in. And after those cells get a chance to mature into muscle fibers, we might harvest the cells,
