Dr. Mark Post hopes to bring the dream of cultured meat one step closer to reality when he unveils his high tech hamburger in London. The five ounce burger is composed of 20,000 strips of beef muscle tissue grown in a laboratory at a cost of $325,000 (provided by an anonymous donor.) From the article: "The hamburger, assembled from tiny bits of beef muscle tissue grown in a laboratory and to be cooked and eaten at an event in London, perhaps in a few weeks, is meant to show the world — including potential sources of research funds — that so-called in-Vitro meat, or cultured meat, is a reality."
