Medical researchers and scientists have created all kinds of medical marvels, from brain tissue and cartilage to a heart and a pancreas, by 3D printing stem cells. In Australia, Swinburne University of Technology PhD candidate Lilith Caballero Aguilar is currently collaborating on a project with surgeons and researchers at BioFab3D@ACMD, the country's first bioengineering facility based in a hospital, about how stem cells are fed once they're inside the body. She is working to develop methods to control the rate of release for growth factors, which stem cells need for development once they've been implanted, and the research could help doctors use biological 3D printing techniques to regenerate damaged or missing tissue.
