Researchers from institutions, including the University of Tokyo, released a single photo of the 1.5-centimetre-thick steak that they had grown in a lab at a research reporting conference on Aug. 29. The red meat looked tender and was complete with white sinews of fat. It was reported to weigh about 30 grams and measure 5.5 cm by 4 cm across. Shoji Takeuchi, a tissue engineering expert and professor at the Tokyo institution's Graduate School of Information Science and Technology, announced the announcement. Since 2017, he has been working on cultured meat with the support of Nissin Foods Holdings Co. and others. The team used muscle cells taken from cows. After finely chopping them to pieces, it took the cells about a week of culturing to grow to around 100 million. Ground meat made from cultured cells mixed with binding agents already exists, but the researchers aim to cultivate steak meat in a form that feels close to real meat when eaten.
