Using 3-D printing, scientists have created tiny, intricate tubes that work like key components of real kidneys.
Many more steps are needed before they can make artificial kidney replacement parts, but the result is important because it means that for the first time researchers have used 3-D printing to make kidney tissue that functions like the real thing. The inventors say that in the near term the artificial tissue could be used outside the body to assist in people who have lost renal function, and for testing the toxicity of new drugs…
