London: Scientists have claimed they would serve the world`s first testtube hamburger this October.A team, led by Prof Mark Post of Maastricht University in the Netherlands, says it has already grown artificial meat in the laboratory, and now aims to create a hamburger, identical to a real stuff, by generating strips of meat from stem cells.The finished product is expected to cost nearly 220,000 pounds, `The Daily Telegraph` reported. Prof Post said his team has successfully replicated the process with cow cells and calf serum, bringing the first artificial burger a step closer. "In October we are going to provide a proof of concept showing out of stem cells, we can make a product that looks, feels and hopefully tastes like meat," he was quoted by theBritish newspaper as saying. Although it is possible to extract a limited number of stem cells from cows without killing them, the scientists say the most efficient way of taking the process forward wouldstill involve slaughter. He said: "Eventually my vision is that you have a limited herd of donor animals in the world that you keep in stock and that you get your cells form there. Each animal will be able to produce about a million times more meat through the lab- based technique than through traditional method of butchery."According to the scientists, making a complete burger will require 3,000 strips of muscle tissue, each of which measures about three cm long by 1.5 cm wide, with a thicknessof half-a-millimetre and takes six weeks to produce. The meat will then be ground up with 200 strips of fat tissue, produced in the same way, to make a hamburger. To produce the meat, stem cells are placed in a broth containingvital nutrients and serum from a cow foetus which allow them to grow into muscle cells and multiply up to 30 times.
