Getty Images Lab Wagyu Scientists at Osaka University in Japan have managed to print lab-grown steak that they say greatly resembles products made from the world-renowned breeds of Wagyu beef cattle — an environmentally conscious and sustainable alternative to a genuine delicacy. The team harvested two types of stem cells from Wagyu cows, incubated them, and then converted them into muscle, fat, and blood vessel cells, as detailed in a new paper published in the journal Nature Communications . The end product is a three-dimensional stack, five by 10 millimeters in size, of high fat content steak that features the intricate marbling of Wagyu beef. “Using the histological structure of Wagyu beef as a blueprint, we have developed a 3D-printing method that can produce tailor-made complex structures, like muscle fibers, fat, and blood vessels,” said lead author Dong-Hee Kang in a statement . Custom Steaks The scientists say that the process could even be used to create fully customized pieces of Wagyu steak, a dream for any meat lover willing to give lab-grown beef a try. “By improving this technology, it will be possible to not only reproduce complex meat structures, such as the beautiful sashi of Wagyu beef, […]
