Dutch researchers grow world's first test tube hamburger

  • 9 years ago
Vascular biologist Mark Post and his team have created the world's first lab-grown hamburger at a cost of $345,000 at the University of Maastricht in the Netherlands, according to a Reuters report.

The assembly of the hamburger begins with stem cells harvested from the necks of cows obtained from slaughterhouses.

The cells are then put in a container along with a growth medium and allowed to grow and divide, repeatedly doubling over a period of around three weeks.

Next, they're placed in a plastic dish along with a dab of gel and starved of nutrients, forcing them to differentiate and merge into primitive muscle fibers and in turn tiny strips of tissue.

A few thousand of these strips are packed together, along with a few strips of lab-grown fat, to create a five-ounce hamburger.

Dr. Post, plans to cook and serve the burgers at an event in London in a few weeks' time.

In an interview with the New York Times Post spoke of his hope that the technology would eventually greatly reduce the number of cattle around the world.
