This article seems to say that it's possible to create the complex structure of a steak today. Is there any more of a reliable source that discusses the actual implementation of lab grown steak? Ground or minced beef exists.
Toubia said each of the thinly-sliced steaks they made as part of this prototype took 2-3 weeks to produce and cost $50.
It just seems unlikely that an actual steak, other than the one quoted, has been synthetically designed. The article is supplementary to show that some form of steak already exists. What about steak that is of complex enough structure to emulate sirloin, T-bone, etc?
Should this question be moved to the biology SE?
