Weighing 3.67 ounces, the steak is made from real fat and muscle cells taken from tissue samples of a living cow and produces astatically pleasing grill marks when cooked. Living bovine stem cells were added to the 'bio-inks,' along with stem cells, which were then placed in a 3D printer to produce the steak. The printed slab of 'meat' was then matured in an incubator, allowing the stems cells were differentiated into fat and muscle cells that develop into fat and muscle tissues. Lab-grown meat is gaining traction into the food industry and in August, scientists revealed the world's first 3D-printed Wagyu beef has been revealed by scientists, who say it has marbling 'just like the real thing' and is grown from stem cells in the lab.
