MeaTech 3D created the 4oz steak using 3D printing with real bovine cells that mature into muscle and fat
The largest lab-grown steak yet produced has been unveiled by the Israeli company MeaTech 3D, weighing in at nearly 4oz (110 grams).
The steak is composed of real muscle and fat cells, derived from tissue samples taken from a cow. Living bovine stem cells were incorporated into “bio-inks” that were then placed in the company’s 3D printer to produce the steak. It was then matured in an incubator, in which the stem cells differentiated into fat and muscle cells.
