Hear This 2017: Scientists Are Creating New Ears with 3D-Printing and Human Stem Cells
January 3, 2017
(Smithsonian) – Now, a team of researchers from the U.S. and U.K. are aiming to change that. Inspired by the earmouse, doctors at the University of California at Los Angeles and the University of Edinburgh’s Centre for Regenerative Medicine have perfected a new technique to grow a fully formed human ear, using patients’ own stem cells. They begin with a 3D-printed polymer mold of an ear, which is then implanted with stem cells drawn from fat. As these stem cells differentiate into cartilage, the polymer scaffold degrades, leaving a full “ear” made of mature cartilage cells.
