...using tons of FBS (fetal bovine serum) in the process.

FBS is essentially a magic mix of animal growth factors, and no good serum replacement exists for cell culture.

That is the issue. Not only is it essentially a magic mix made of meat, but it's also extraordinarily (and irreducibly) expensive compared to every other component/process. Whoever fixes the 'FBS Problem' will do well - but until then, these unfortunately seem to be fancy, expensive experiments.
