It is also, rather expensive:
The only problem was that no one was interested in eating his fish nuggets, perhaps because his tiny goldfish filets matured in something called fetal calf serum.
Matheny estimates that a kilogram of laboratory meat would cost about half a million dollars if it were grown in calf serum.
In order to make faux meat a reality, then, one of the first tasks is to develop an inexpensive ersatz nutrient solution from plants or mushrooms. Maitake mushrooms, for example, have already proved to be a possible alternative.
