From its striking colors, beautiful striations, and amazing layers of marbling and fat, meat is truly an wondrous thing. That’s why figuring out how to culture it without animals is such an exciting challenge! For cultured meat researchers, meat’s complex structure of muscle fibers and intricate network of blood vessels and fat cells are like a massive puzzle to be carefully studied, understood and painstakingly reproduced. Thankfully, this crucial investigational work has already begun, and we can look forward to a day when large cuts of meat, like the steaks, filets, and roasts above, are grown directly from cultured tissue, no animals necessary!
