Researchers from Japan with the help of stem cells received from cows printed on a 3D printer marble beef wagu. The work of scientists was published in the magazine Nature Communications.
Beef Wagu is considered to be the most expensive in the world – contains a large amount of intramuscular fat, giving meat characteristic taste and marble pattern. Researchers from Osak University with the help of 3D printing tried to recreate its texture as accurately as possible. “Using the histological structure of beef Wagi as a layout, we have developed a 3D printing method that allows you to reproduce complex structures with specified characteristics – such as muscle fibers, fat and blood vessels,” said one of the authors of research Kan Don Hee.
scientists used two types of multipotent stem cells – miosatellite (muscle tissue cells) and mesenchymal stem cells of adipose tissue. From them, 72 fibers (42 muscular fabrics, 28 fat and two capillaries) were obtained by biopinger on the gel of collagen tendons, which then transformed into a three-dimensional structure.
According to researchers, their technology will allow consumers to personalize the necessary meat under itself on the basis of taste and dietary preferences in the future.
