Researchers at the University of Maastricht in the Netherlands say they expect to serve
the first burger grown from bovine stem cells later this year.
Professor Mark Post, who reported growing small strips of meat from a pig’s stem cells last year, says his team has been able to repeat the process using stem cells from a cow and a serum taken from a calf fetus.
“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,” Post said at the annual meeting of the American Academy for the Advancement of Science.
Unfortunately, the most efficient way to extract stem cells from cows still involves killing them, but Post says his process could produce a million times more meat per cow than the current method of butchery.
Each lab-grown burger requires 3,000 strips of muscle tissue and 200 strips of fat tissue. The strips currently take about six weeks to produce.
Post says the $350,000 burger is being financed by a wealthy and famous benefactor who chooses to remain anonymous, and celebrity chef Heston Blumenthal has been invited to cook the first specimen.
