Creating realistic 3D structure for laboratory-grown meat has been a technical challenge, partly because of the difficulty in getting oxygen to the cells in the middle of a piece of cultured tissue. However, Israeli startup Aleph Farms says it may have the solution.
CEO Didier Toubia claims that Aleph Farms grow together four different types of cell - muscle, fat, blood vessels and connective tissue - to create a more realistic 3D texture. It’s not clear whether the blood vessel tissue actually contributes to oxygen transport. Aleph Farms also claimed to have found an alternative to foetal bovine serum in the growth medium, but did not give details.
