Researchers have motivated a step closer to creating an artificial liver, following a US team fashioned a template for blood vessels to grow into, using sugar. The technology, in which a 3D printer uses sugar as its construction material, could one day be used for transplants. Sugar is a very nice material that can be dissolved away in the presence of living tissue very responsive to organic tissue.
According to Dr Miller's colleague Prof Sangeeta Bhatia, from MIT, the technique was comparable to creating the shape of a vase in wax, neighboring it with molten metal and then melting the wax away. Sugar is a very good material that can be dissolved away in the presence of living tissue very forthcoming to organic tissue. The body's cardiovascular system blood vessels resolve this problem with natural cells and tissues.
