Food colouring paves the way for 3D-printed organs
Tatrazine could overcome biocompatibility problems of printed tissues
US researchers have found that a yellow food colouring can be used to make complex bioprinted tubular structures akin to the vascular networks that transport blood, air and other vital fluids in our bodies. The work overcomes a major biocompatibility hurdle in tissue engineering and could lead to 3D-printed organs for transplant made from a patient’s own cells.
