In the nascent lab-grown-meat space, the products come in tiny pieces—shredded, diced, or melded together. Larger pieces of meat would require a constant feed of nutrients and oxygen to every cell in order to grow. In April, researchers at the University of Tokyo revealed they had done just that, creating what is likely the largest piece of lab-grown meat to date: a nugget-sized chunk of chicken. The scientists engineered a faux circulatory system out of tiny permeable (and inedible) tubes threaded through the meat. Still experimental, the nugget marks a major step toward real slabs sans animal.
