Researchers at Boston College have grown meat cells on spinach leaves, potentially providing a cost-effective and environmentally friendly solution for the production of cultured beef. The study, led by engineer Glenn Godette, involved removing plant cells from the spinach leaf, leaving the vascular base to support growing meat precursor cells. These cells successfully differentiated into muscle mass and remained viable for up to two weeks. The team is now exploring other vegetables, animal and fish cells for this cultivation method.
